Wellcraft 202 nova spyder repower

[silver_power]

Hello to everyone and congratulations for this awesome forum.
I am from Greece and i own a 1993 wellcraft nova spyder with 5.7LX 4bbl engine.(260hp@crankshaft). The boat is in GREAT condition and i really love it the way it runs at travels (22deg V). With this engine reaches at speedo 59mph@4600rpm with an 22p enertia (at speedo). All these until last year that my engine was ruined. So i decided to repower it with the new 350mag mpi.Mercury said that this engine is fully compatible with my Alpha one genII drive (gear ratio 1.47:1) and so i bought it and now i am waiting for it . I also got smartcarft gauges (sc1000 speedo-tacho and the link sc100 gauges). The engine instalation will be made by me as the instument installation.
I want to ask you what opinion do you have about the specific engine (350 mag mpi) consernig the power and the fuel consumption and what speed should i expect with the same prop.I believe that the prop will be ok and the new engine will reach 5000+rpms. Second question is about the pitot speedo sensor and also the fuel level sender. Where am i going to connect them, since the new gauges take data from ecu. So, somehow i need to connect the pitot sensor and also the fuel level sender with the engine and not directly to the gauges as it is now with the old gauges. Are there any specific inputs (leads, or anything else) around the engine particular for these sensors? For example, i know that the smartcraft depth sensor (transom mount) that i also bought will be connected at a terminal side to the smartcraft link terminal at the ecu of the engine.
Every answer would help me very much during installation.
Thank you very much in advance.

Re: Wellcraft 202 nova spyder repower

Hi well to start I think your speed o meter might be off a little, I think it should be more arond 53-55 MPH right now as that is normal speeds, But that is just guess, And I would think the new engine will give you about 4-5 more mph as an avarage, And fuel consumption will be about the same as you should be use to now with the old engine. you should be able to run the same prop as long as you can get the rpms as close to the max rpm rating with a light load in the boat. do you know if the new smartcraft system will be coming with the wire harness to make it work from the engine to the helm? and also to make the fuel sending unit and the new style speed o pick up work you will need the new sensors are they coming with the kit or do you need to order them still? You will need a wire harness to go from the sensors to the engine that will just plug in then you just plug in the main harness from the helm to the engine. Now there will be some calibrations you will need to do to make somethings work.Did they say it is coming with a service type manual of any kind so you have something to go by to hook it up? On the trim are you going to leave the old gauge and sending unit in or are you going to install the new style smart craft sending units in B/C you will need to calibrate them to work and there should be a certin way to stop the smart craft gauge from showing it as a fault code. Right now all I remember is there is a master reset you need to do to get it to stop if you do not use the new style system.Well good luck with the install I know I have just touched the basic stuff but a smart craft service manual and time is what you will need to set it all up. Also there is only one way you can run the main wire harness from the engine to the helm If you get the harness reversed it will not work right. I have had to change a few around from the boat factory before

Re: Wellcraft 202 nova spyder repower

You are totaly correct about the speed accurancy.The maximum speed i could see was about 54-56mph while boat's speedo rans between 57-59mph. Regarding the smartcraft gauges, i think that each gauge comes with it's own harness. I believe that the same happens for the sensors too. Together with the engine and the smartcraft gauges i have already bought the followings.
Depth Sensor part #881931A11
Switch Kit Part #897716K01
Boat Hardness Part #896537T15 (harness from engine to helm)
Speedo sensor pitot kit 100psi part # 881879A13
Junction box part # 878492K14
Data harness part # 879982T20
For example the fuel level sender has 2 cables (pink/black). Where am i going to connect these cables so to take a reading from the smartcraft fuel gauge?
And second, my current speedo is connected to the alpha drive with a pressure hose. I believe that this hose now will be connected with the pitot speed sensor. This sensor obviously will have some cables. Where am i going to connect them.
Is there anything else (ex more harnesses) that i have to buy so to make them all work properly. Thank you very much for the trim gauge tip, Do you know something more spesific of what will i need to make the new smartcraft trim gauge work properly?( Which sensors, harnesses etc..)
Thank you very much.

Re: Wellcraft 202 nova spyder repower

Generally is there anything specific that i must take care off especially for the Smartcraft gauges installation with the harnesses i have bought.? At post #2 i describe exactly what have i bought and what is my possible problem.
Thank you very much!

Hello there,

You can find alot of this info in my "how to install a smaercraft system" thread.....

the tach and speedo will have their own short harnesses, they both will connect to a junction box at the helm. Then you will use a main harness to go from the junction box diesctly to the smartcraft connector on the engine.
to connect the smartcraft system to the fuel tank(s) you will need a separate harness "fuel/ oil/ paddlewheel harness" this will connect one wire to each of your sending units (the other wire on the units must go to ground (most likely it does now)) this harness also connects your depth and paddle wheel and sea temp sensors to the ENGINE (another connector), it does not connect to the other smartcraft harness.

is your engine new?? it should have the digital pitot sensor installed (you can see pics of it on my outboard on that other thread I mentioned) if not you will need to buy it and install it, not a big deal, just hooks up to a little water tube at your engine. I am not super familiar with inboards, this is direct outboard knowledge, but it should be the same or similar!

Re: Wellcraft 202 nova spyder repower

So the only way for me to connect the fuel level sender on to my engine is to connect the "oil/fuel/paddlewheel" harness to the engine and to the sensor. Regarding the speed sensor...well my boat is 1993 and it obviously does not have the digital speed sensor. It has the classic water tube that comes from the alpha drive directly to the speedo at the helm. As you can see at the previous post i have already bought the pitot speed sensor. This is the sensor you are talking about? Does the new engine (350mag mpi) have any particular input for this sensor?I was hoping that this sensor will be connected in the one side with the water tube of the drive and at the other side at the engine but ny question is if the sensor will be connected to the engine with any spesific harness that i have to buy extra or it comes with the sensor?
Thank you very much and i am sorry for my poor english.....i hope you undersand what i mean...

Hi, I believe you might want to see if you can down load and open this link up. http://www.4shared.com/file/116199483/81790cc7/cover36.html. I believe it might give you some info you are looking for.Also you might want to try to PM [Rotor Fixer] Just to let him now you seen his post, Because I believe he does not come in this area that offten, And He wrote some good info for you, And looking at his past post he knows the smart craft varry well, as most outboard guy's do because they get to see and work on more of them then some of the sterndrive guy's do, In general that is. Anyways good luck with it And I hope this link helps you out some.

Hello again.

Your english is great! Yes the fuel oil paddle wheel harness is the only option to connect the fuel sensor to the system. The new engine came with a new leg right? So there should be a water tube that comes to the engine area. This is where I imagine you should see the sensor connected or where you should connect one. Again I am not a marine mechanic, just a guy that had to teach himself about this to be able to install it on my boat. I have helped a lot of people since! Also look at my other thread "how to install a smartcraft system" for info and pictures of the pilot sensor installed.

Re: Wellcraft 202 nova spyder repower

Well, i will not change the drive. I allready have the alpha one genII which is compatible with 350Mag mpi. Yes, now there is a water tube that comes from the drive directly to the speedo meter to the helm. Now, i suppose i will cut this very long tube near to the pitot sensor so to connect with it. And the sensor will be connexted with the engine so to transfer data to the ecu and then to smartcraft speedo. Am i right?
Thank you very much for your help.

 

[Rotorfixer]

Re: Wellcraft 202 nova spyder repower

OK, that makes sense, then yes you will want to look for a connector that is capped off in your engine somewhere (I have pics of it in the other thread, but if yours has no sensor it will have a weather cap on it!) and route the water tube there, attach the water tube to the sensor and the sensor to the connector on your engine. Let me know how you make out!

Re: Wellcraft 202 nova spyder repower

So i think that there will be no problem with pitot sensor installation.Thank you very much for you information and your help. I will post to let you know as soon as i will install it. My engine and the hole freight wit the other accesories will depart from Miami 2 of August and i really looking forward for it to come and feel my boat with the new engine and about +90hp totaly new power!!!

Re: Wellcraft 202 nova spyder repower

Hello again, the repower project of my boat has started. I missed the summer and i did not work at all till now because of my work. The new engine arrived in Greece and it really awesome. Well my old engine has been already put off the boat.I started with the electric staff, before i procceed with the engine installation. I have already put the Smartcraft gauges at the dashboard and i love them. Soon i will post you some photos. Well, i have some questions.
1. The completely new 14pin engine harness, can be used for power supply for boat accesories. But there is an upper limit to 15Amps. My boat has a radio-cd, bilge pump, blower,lights and a plug for a headlight. Do you think that it is necessary to install the power harness with the 40Amp fuse, or i can use the accesory plug of the engine harness with the 15amp fuse?
2. The new engine comes with the drive lube monitor kit. I ordered the Gimball Housing Fitting for this application as my Gimball has a screw now at that place. I am afraid i will need also a drive valve stem which is placed at the transom assembly because now there is a hole with a small ball inside, which if itis pushed, then drive lubricant will leack. Is there anything else i will need to make the drive lube monitor system work in my boat please let me know.
3. The new engine came with new "quick connected" power steering and new "Quick Connected" power trim pump. My previous application was not with quick connectors so as you understand there is an incopatibility. When i ordered the engine, Mercury adviced me to get quick connectos so to connect my old power steering with the new engine and so i ordered them and there is no problem with the power steering. But there is a problem with the power trim pump, since my hoses does not have quick connectors and the pump has. I put the connectors off the pump but the hoses can not be scred. Is there a Mercury part which i must take , like an adapter, so to connect my old hose with the new quick conected power trim pump?
Sorry for the long post but i try to be as specific as i can because my English are not very well.
Thank you very much in advance.!

Re: Wellcraft 202 nova spyder repower

Hi, I'm not 100% sure about Question #1, I would hate to tell you the wrong thing myself.

Question #2 Didn't your old set up already have a drive lube monitor bottle with a rubber hose going down to the Transom/Drive area?
With the drive off the boat does your bell housing have # 33 & 17 In this link? http://www.mercruiserparts.com/Show...91/9.png&inbr=1017&bnbr=50&bdesc=BELL+HOUSING If your set up already has this stuff then you should be fine, You just may need to extend the rubber hose out some on the inside of the boat to get the bottle to sit where the new bracket is mounted on the new engine. If your set up does not have have any of this then it will depend on you if want to install everything to make it work.

Question #3. To make the trim stuff work You will need to make sure you have # 2 & 4 in this link. http://www.mercruiserparts.com/Show...inders+and+Hydraulic+Hoses(Standard+Transoms) .

And also you will need #'s, 5, 6, 7, 8, in this link. http://www.mercruiserparts.com/Show...bnbr=170&bdesc=Trim+Pump+and+Motor+Components

Re: Wellcraft 202 nova spyder repower

Thank you very much, Your post was very helpful.And something last...
I put new fuel sender unit (Royce) compatible with the smartcraft gauges (240-33 Ohm). The fuel sender has 2 cables (red + black). I know that the sender will be connected at the "fuel,oil,paddle wheel" harness. But this harness has only one lead (I think orange coloured). So my question is which wire of the fuel sender will be connected with the harness and also where will i connect the other wire of the fuel sender?
Thank you very much.

Thank you very much.

Becarefull with the orange wire because my book is showing the wire going to the fuel sending unit out of a wire harness style plug is pink with a black strip, But maybe the pink/black wire will plug into a orange wire as for some reason that ring's a bell to me with out looking it up. Also the book is saying to use a normal ground wire that more then likely is already there at the fuel sending unit from the stock unit, The book said to ground it to the battery. Now becarefull if you have a black wire with a orange strip do not hook it up with any other grounds at all or you Could damage the [PCM] or have a high idle or fault codes, Ect. Well the red from the fuel sender should hook up to the pink with black strip. And the black from the fuel sending unit should hook up to the ground wire that is already there i'm sure and noramly that ground is already going to the battery in some way, So you should be fine.

Re: Wellcraft 202 nova spyder repower

Well i just checked the colors. The boat has two cables for fuel sender connection. One pink and one black. So untill now, my old fuel sender was been connected with one pink and one black wire. My new fuel sender has 2 wires. One red and one black.The new "fuel, oil, paddle wheel harness" has one pink wire with a black strip, just as you said. So all i need to do ,if i understood well, is to connect the red wire from the new fuel sender to the pink with black strip wire of the new harness and the black wire of the fuel sender, with the old black cable of the boat? I think that it will be ok because i think that this old black cable is the ground for the fuel sender. Am i right? So, red(fuel sender) with pink+black stripe(new harness), and black(fuel sender) with black (old boat harness).

Well my old set up did not have the drive lube monitor bottle with a rubber hose going down to the transom. I can not see if my bell has the #17. But for sure it does not have the Valve assembly #33. At this position the bell has an empty hole. And there the drive has a hole with a little ball inside which if pushed, drive lubricant will come outside.For sure i can tell you that the gimball inside, at the place where the hose from the drive lube monitor reservoir must be connected, side to the sea watertube, has a nut screwed.
As i will put off the bell because i will replace the transom bellows, can you please tell me ,if you know, if i put the #33 part you told me, which parts of the following schema must i also put? Please check the following:
http://www.perfprotech.com/store/as...NTS-(ROUND-OIL-BOTTLE),1017-180.aspx#assembly
I must tell you that i allready have the parts #5,6,7,9,10,11 and the reservoir as they came set with the new engine (http://www.mercruiserparts.com/Show...0&bnbr=240&bdesc=Gear+Lube+Monitor+Components)
In case i can install the drive lube monitor, and because the set i have from the new engine has hose with quick connect, if i buy the #1 from the second url i gave you previously instead of #1 of the first url i gave you, will it fit at my gimbal. The first url is the drive lube monitor kit for alpha drive genII year 1993 as mine is. The difference from the other part is that it has not quick connect.
I hope i have not started to make you dizzy with my questions.......
Thank you very much.

Re: Wellcraft 202 nova spyder repower

Well you have found all of the parts needed to make this happen, Because you already have #'s 5,6,7,9,10,11,12, You will need #'s 1,2,3,4,6,8, [Side note #1 comes with the orings] So you will need more of #6 & #4, Just lube the orings or you will need to buy more also. So you will need every thing to the left of your #5 in this next link, The hose with out the number to it is #17 in the other link I first showed you. You might need to drill or and tap the hole to fit #8 in the bell housing or i'm not 100% sure but it kind of looks like you may get lucky and you might be able to remove A plug, #4, And then install #8 with out tapping, Also installing the plunger #33 with #34 from the other link.Here is the first link. http://www.mercruiserparts.com/Show...0&bnbr=240&bdesc=Gear+Lube+Monitor+Components


From this next link you will need numbers 33,34,3,18,17, [Side note numbers 3 & 8 are the same fitting but different part number's so it looks like it depends on if you can remove the plug or not to know what fitting you really do need So if you can I would just buy both so you are ready for it or go pull it a part and look before ordering] http://www.mercruiserparts.com/Show...91/9.png&inbr=1017&bnbr=50&bdesc=BELL+HOUSING

Keep in mind they had two style fittings that goes through the transom assy, One was like a brass style that was held on with a nut at the end, And the hose was clamped to the fitting, Now they have a plastic style with orings and it's held on with a C clip for the Quick link system you now have that is new to you. Even though I have not done it myself yet I believe the new style fitting part #22-861150A2 should fit in to the transom assy, You have on your boat now, But before installing the engine you should run some water from the garden hose in that area on the out side of the boat to check for leaks on the inside from that fitting. If it leaks then you will need the old style fitting Part #22-18922 And you will not get to use the Quick link system. Now to install that fitting I believe you are going to need to remove plug #14 from this link from the inside of the boat, [I believe But not 100% sure,] You will half to look it over to see if every thing lines up to be sure.http://www.mercruiserparts.com/Show.../5.png&inbr=1017&bnbr=30&bdesc=GIMBAL+HOUSING

Also you will need the stern drive gasket set to install the drive with the hole in the gasket for the new plunger, See part #2 in one of the links above. Good luck with it. I Hope to see photos some day with all of this new stuff going in.
