New to forum and got a Problem already

[craig mac]

Hi there, i bought a Speedboat last year with a Johnson 150 VRO V6 outboard on it, now i have had a number of problems with the boat, including water seperator, new steering kit, new fuel line, full service, new tilt and trim, and rewired the two main leads fom the battery.

Now, on Sunday when we thought everything was all ok, we had the boat started about 3 times on land and everything was fine, however when we got it into the water and took of after about 5 Miniutes the engine just conked out.

We tried the cold start and it was just dying, say after a few seconds, we kept on trying it and no matter how many times we tried to start it, it just kept on dying, the only way we could keep it going, was if the cold start leaver was all the way up and we pushed the key into the ignition, which in essence was no good to us as we could not go go anywhere.

So we dropped the anchor, the fuel ball was rock solid so we were confused as to what on earth is wrong with the engine now!

Seen as we have thrown so much money at it all ready, my self and my mate want to investigate the problems ourselves with all the help we can get off forums, and out of manuals, so we would appreciate your help so we can fix this problem,

Also in order for us to purchase the correct manuals, we are unsure on what ones to buy as we are not sure on the year

However my mate has got these following details:

Johnson 150 VRO V6

Model No T150T1C118

Serial No B7495975

So all he help would be appreciated both in guidence on here and on what manuals to buy

Thanks Craig

Re: New to forum and got a Problem already

If you have to keep the key pushed in (opens the primer) to keep it running, it's starving for fuel. I'd suggest a good carb bath to start with. It'll run on land because there is no backpressure in the exhaust.

Also make sure there is no restriction in the line from the bulb to the motor. (Make sure the bulb is pointing the right direction too) No kinked line, the "in" and "out' on the water seperator are right etc.

Re: New to forum and got a Problem already

Please recheck your model number. That one doesn't make sense. A 150TLCIx would be a 1981 (x meaning an unknown)

Re: New to forum and got a Problem already

Right i have some updates since i last posted

Model Number is J150TLCUR
Serial No: R7495975

I have undone and retightend every connection from the fuel tank to the engine, no kinks, and fuel is getting through

We have taken all 3 Carbs off, however you mention i "bath" them, (now i am new to this so what exactly do you "bath" them in? also, when i took them off, the three seals had all cracked or gone hard, so i am going to replace them, (would these seals be the cause as to why why the engine is spluttering)

We disconnected the water seprator filter and that is doing its job! so thats has been put back on.

Also would it be an idea when i re connect the hoses onto the carbs, shall i use a jubilee clip as opposed to cable ties?

Re: New to forum and got a Problem already

what he meant was to clean out the carbs with carb cleaner (bath) and how old is your fuel?? and is the tank vented??

Re: New to forum and got a Problem already

By "seals" do you mean the carb gaskets (where they attach to the powerhead). If those are cracked, nasty, or just not sealing up properly you can have all kinds of issues like the ones you describe.

As for the bath. You can get a 1-gal can of carburetor sklorbing chem-o-lisciousness at an auto parts dealer. It's a paint can looking thing. It'll have a little metal basket to put all the goodies in. Remove all the plastic and rubber bits and soak 'em for a couple of hours.

Re: New to forum and got a Problem already

Its an 87. Look on ebay for a manual.

Re: New to forum and got a Problem already

Right the fuel is brand new, and the tank is vented, the vent is near the front, but water may have got down them,

Also the seals are like a "rubbery paper thing" that sat in between the carbs and the main head, there was three of them

Re: New to forum and got a Problem already

From what I see these are the right books for that engine. Am I right?

http://www.outboardbooks.com/index.cfm?fuseaction=models.main&year=1987&ID=123265

That makes it a 1987

Edit: The R at the end of the model number they provide means that it was rebuilt??? Is that correct?

Re: New to forum and got a Problem already

DHadley was right, it sounds like the motor is starving for fuel, I am no expert in outboards, except I have had a couple of kicker motors, but all motors will act the same when starving, there should be a check valve on your tank that might be blogged up, start at tank and work your way up, first clean the carbs, and (maybe water)???? when in doubt change it

Re: New to forum and got a Problem already

If it was running while choked, it was getting fuel to the carbs. And, if those gaskets were as bad off as you say, it was sucking air in through the carb flanges. There's about no way it's going to idle properly if that's the case. You've got your carbs off now. Rebuild them, soak 'em good, clean out the idle jets, put them back on with new gaskets. Dollars to donuts you'll be up and running.

Edit: Gaskets don't get like that all by themselves. You might want to check the faces of the carb flange with a straight edge and make sure they're nice and flat. Make sure you don't over-tighten when you put them back on.

Re: New to forum and got a Problem already

ok we will try and get some gaskets tomorrow, just a quick question?

what are idle jets as i am not sure untill iahve ordered the manuals

 

[iwombat]

Re: New to forum and got a Problem already

Get yourself a carb rebuild kit for each carb. They'll have the gaskets in them. Read the carb rebuild section in your manual when you get it and post any questions you have before doing the teardown here. It's a pretty simple procedure, but sometimes the written steps can be tough to follow without some extra help.

The idle jets are in one of the passages in the carb body. All covered in the manual.

Re: New to forum and got a Problem already

Well everything seemed to go back ok after the carb clean, however some of the throttle cable and the cold start cable were all out, but have since been adjusted, and the engine seems to start ok and run pretty good,

However the tilt and trim has started to play up now.

After some Fault diagnosis, ie changed relays and tested the wiring, the fault is in the actual lift, for example when you lift the engine all the way up, the unit on the left hand side as you look at it face on,

When i hit it with a hammer it comes down, goes up perfectly but tempremental coming down.

Any hints or tips to solve this, and i m struggling to get to it ie the 3 fixing screws are in a triangular formation and a proving difficuilt to access, as it probably needs to come off and looked at.

Also will it need to a new one or could it possibly be repaired???

Re: New to forum and got a Problem already

First off check the manual release valve. If good, check the 20 amp inline fuse at the solenoid, it controls the up function. Rest the motor on the trail lock and check the oil resevoir level. Determine if electric motor is even running. Here is a test for the electrical.

Note to Darrklim:The letter at the end is the model run or suffix, manufacturers wouldnt know ahead of time if the motor is going to be rebuilt,


1. Make sure battery is FULLY charged.

2. With a voltmeter, connect red lead to point E1 in junction box and meter black lead to point G. Meter should indicate battery voltage.

3. If no voltage is indicated, move meter red lead to poiint E2 on solenoid. If battery voltage is indicated check FUSE in junction box. If no voltage, check red and black leads to battery for poor connection or open circuit. Polish them up, no corrosion, dirt, rust, etc...

DOWN CIRCUIT

1. Move red meter lead to point E3 in junction box, push trim switch in the down position. Battery voltage should be indicated. If trim motor does not run, test motor.

2. If no voltage is indicated at point E3, move meter red lead to trim switch at point E4 and meter black lead to point G1. Push trim switch in down position. If meter indicates battery voltage, lead is open between point E3 and E4.

3. If no voltage at point E4, move meter red lead to point E5 in trim switch. If battery voltage is indicated, trim switch may be defective.

4. If no voltage is indicated at point E5, check continuity of ground lead from trim gauge G1 to junction box point G. If ground lead is good, move meter red lead to junction box at point E1 and meter black lead to point G on junction box. If battery voltage is indicated, lead is open between E1 and E5.

UP CIRCUIT

1. Connect voltmeter red lead to junction box at point E6 and meter black lead to ground at point G. Push trim switch up. Battery voltage should be indicated. If trim motor does not run, test motor.

2. If no voltage is indicated at point E6, move meter red lead to point E7 on solenoid. Push trim switch in up position. If voltage is indicated, blue lead is open between E6 and E7.

3. If no voltage is indicated at E7, move meter red lead to point E8. Push trim switch in up position. Battery voltage should be indicated. If trim motor does not run, connect meter red lead to point E2 on solenoid. If battery voltage id indicated, solenoid is DEFECTIVE and must be replaced.

4. If no voltage is indicated at point E8 on solenoid, move meter red lead to point E9 and meter black lead to ground at point G1 on trim gauge. Push trim switch in up position. Battery voltage should be indicated. If battery voltage is indicated, lead is open between E8 and E9.

5. If no voltage is indicated at E9, move meter red lead to point E5 on trim switch. If voltage is indicated, switch is defective and must be replaced.

6. If no voltage is indicated at E5, check continuity of ground lead between trim gauge G1 to G in junction box for open circuit.

7. If ground lead is good and no voltage at E5, move meter red lead to E1 in junction box. If voltage is indicated, lead is open between E5 and E1.

TRIM INDICATOR CIRCUIT

1. Connect voltmeter ted lead to point E10 on indicator gauge and black lead to G1 on indicator gauge. If battery voltage is indicated, proceed to step 4.

2. If no voltage indicated at E10, move meter red lead to horn at point E11. Battery voltage indicated lead is open between horn and trim indicator gauge.

3. If no voltage, move meter red lead to point E12 on key switch. Battery voltage should indicate. If no, check key switch. If key switch good, check engine fuse and lead to key switch for open circuit.

4. Disconnect tan/white lead from "S" terminal of trim gauge. Connect ohmmeter to disconnected lead "ohm1" and to G1.

With the motor in the full trim position, ohmmeter should read 82 to 88 ohms. With the motor in full tilt, ohmmeter should read 0 to 10 ohms. If infinite reading check for open circuit between trim gauge "G" terminal and "G" in junction box. Also check for open circuit in tan/white lead with lead disconnected from "S" gauge terminal. Check between "ohm 1" and point "ohm 2" in junction box. Disconnect both black sending unit leads from "ohm2" and "G" terminals. Check for above resistance readings. If not within specs, replace sending unit.

Re: New to forum and got a Problem already

Now in response to removing the trim motor if you must, you will not be able to get at that 3rd screw with the trim unit on the boat. Unbolt the port stern bracket and slide it to the left. Disconnect the steering, unbolt the trim unit and slide it out. You will then be able to get that 3rd screw. You might want to put a chunk of wood in there to support the motor while you only have 1 stern bracket connected.

Re: New to forum and got a Problem already

i had the same problem with my tilt trim motor its the contact inside thats sticking i took mine apart and cleaned it works fine now!
