2003 Evinrude 115hp FICHT RAM oil type please ?

[EDDYSTONE EEL]

Hi ALL

Couple of questions if I may.

First and most important - what type of 2 stroke oil do I need to use. I am used to using quicksilver on the old motor that came off (johnson 90hp v 4 1993 2 stroke) and have been told to keep using that but I am sure I read somewhere that it needs a special type of oil - I have no manual sorry

Also the motor has just been fitted to a 18ft ryds 550GT which is a open sports boat. It gave 35knotts with the 90hp - we mounted the 115 in the same position as that came off and we are having severe handling issues.

It wants to bank right all the time and is quite hard to hold on course at mid-top speed. When it gets up on the plane it tends to dip left and again is difficult to control. When we trow a couple of guys to the bow it seems better. Playing with the tilt (bring it up a bit) seems to help aswell.

Could it be that its too low down, or does it need to be offset from the centre of the boat as I have seen the boat it came off ( 17ft fletcher speed boat) and the bolt holes were slightly to the right of the transom.

Any help would be great please !!!!!!!!!!!!!!!!!!!!!!!!!!!

Use BRP XD50 or XD100 oil. XD100 is an expensive oil, but takes care of any need for decarbonization and is BRP's best oil for DI motors and is used in most E-Tec's.

The turning to port issue ... have you tried adjusting the torque tab just below the AV plate? It should be adjusted in the direction of the helm tendency, in your case to port. Keep adjusting in small increments until the helm is neutral at WOT.

Unless you have one of the new Etech engines, I'd run the XD50. XD50 has a decarbonizing agent already mixed in the oil-a nice feature. As far as the handling issues, a couple of comments. The engine should be mounted vertical-centered on the boat. Insure that the engine is mounted so that the antiventiation plate is just above the water flowing from the transon when on plane and trimmed out. (that plate is the flat one above the prop.) If it is under the water at planing speeds, it causes huge drag and water spray at the back of the boat and will affect performance. You will want to trim the engine out once on plane, as the bow will rise somewhat- improving handling, fuel economy and speed. Running with bow down at planing speeds can also negatively affect handling. Higher hp engines tend to crab to the right due to the rotational effect of the prop. It is normal to have to keep left hand pressure downward on the wheel on higher hp engines with bigger props when at speed. If the steering continues to be objectionable, you can install a no feedback helm or hydraulic steering. I've not had much luck adjusting the tab above the prop, as mine is mostly of the the water when fully trimmed out.

Thanks Guys

I will try that adjustment first and update how it goes

On the oil issue - the tank is 1/4 full of quicksilver I guees. Can I drain that down a little then mix the xd50 with whats left in the bottom. If I drain it fully do I need to bled it etc or just primer it back up

Looking at changing the plugs - again someone told me its not just as simple as normal - are they winding me up or is there something "speical" I need to do ?

Thanks again

Cant wait to get on the water...but I have to until this oil question is sorted

Plugs on BRP DI motors need to be indexed. See here. Needed for proper running.

http://www.boatsetup.com/PlgIndexing.html

One comment about indexing: the plug gap alignment with the injector/pin need NOT be as precise as the article indicates; +/- 90 deg. is OK, but shoot for the best you can get.

No need to get crazy on the oil ... just use most of what's in the tank, then fill with XD50, or whatever you plan to use.

BTW, make sure to adjust the torque tab in small increments and check at WOT for helm balance.

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

Thanks again for the info

My word I never knew what I was letting mysel fin for putting this on the boat. The old motor was a v4 90hp from 1993 and that thing you could do what you wanted with and she still ran all day.

Can I ask what will happen if I get this indexing wrong. Im quite basic in terms of mechanics (I thought a plug change was within my relms of experienc though!)

Anyone want a FICHT 115HP with plug issues.....watch this space

I had a 115 Ficht. Very strong motor. I used XD50 and didn't have to decarb. If the plugs aren't indexed correctly they won't last as long. You can get them at Sparkplugs.com.​

Thanks again guys

I have now put the boat back on the water with the tab as far to the side it wanted to steer and all is well now. Boat shoots along great.

On the plugs issue I have spoken with my local Main dealer who looked in his book and said the plugs dont go in a certain way, he thinks im getting confused with the injectors. He said on the larger ones they do but the 115 is not one which needs it.

He had the service book and showed me it all it said was torque it up to what you guys said but nothing about indexing etc. He reckons I should just be able to insert them as per a normal motor - he should know I guess but you guys seem to know so much more so I am stuck in the middle on that one.

Will leave the plug change for a while anyway boat going into storage for the winter soon.

Thanks again

ALL BRP (Evinrude) DI motors require the plugs to be indexed. The plug opening gap needs to face the injector for that cylinder +/- 90 deg. It won't damage anything if you don't index, but the motor will likely run like crap, your choice.

The way to do this is to take a black Sharpie pen and make a vertical line on the plug porcelain in line with the gap opening, then use the line to get the plug correctly oriented with the pin/injector.

That's a shop that wouldn't get a dime of my service money. It's a pretty well known procedure.

OK, heres my bit, I have a pair of 115HP Fichts that have way over 2,400 hours on them, (each that is) use only XD50 Oil, index the plugs, it is easy to do, find a better marine dealer that knows these engines and you will be more than happy with the motor (once you get it sorted out) they are not all that powerful, and have a very distinct power band, make sure you can get full max RPM, do NOT over prop it! but they are very cheap to run, especially compared to an old carby V4 Evinrude.

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

Thats a good point well made

I will get a new dealer and look at the indexing again.

The prop thats fitted is a 17pitch I think. Gives about 55kmh on a 18ft centre console sports boat which is not much more than the 1993 Johnson 90hp V4 it replaced.

Any suggestings on a replacement prop, should I go for a bigger pitch etc. Normally just used for fast fishing no towing, 3 adults on board most of the time.

What do you mean by make sure I can get full RPM, how can I check it is.

thanks

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

You need a tachometer to check RPM.

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

It came with the rev counter which I guess will give me the rpm when flat out - is that what I need to check. What should the max RPM be on it.

Cheers

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

I think it should be 5250 to 5750 RPM for your motor. I would aim for the high end of the range, i. e. ~ 5700.

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

Thanks Jim I will see what its reading next time im out. If its under that at WOT how can I alter it ?

Re: 2003 Evinrude 115hp FICHT RAM oil type please ?

First
. Make sure the motor is at the proper height. Run at WOT and look at the AV (cav) plate. It should be w/o water on top of it. If it's under water, raise the motor on hole at a time until it's right. Also, experiment with the motor trim for max RPM also. You can pick up a few hundred RPM and greater top speed and fuel economy here. Once this is done, go to

Step Two
. Observe WOT RPM. If still too low, reduce prop pitch (each inch of prop pitch reduction will give ~ 150 to 200 RPM increase). So, i.e. if you read 5300 RPM, reducing pitch 2" would get you close to the 5700 target.
