84 Evinrude 35hp ?

[EZSteury]

Finally after much work and thanks to this forum knowledgeable members I got the motor back together and drove to the bay for a test. I'm glad the motor now starts and runs, of course, I found a few problems.
1- The engine will cut off randomly for a fraction of a second and then continue as if nothing happened, I traced it back to a weak coil that will fire but not very far, the other one must be fine bc when I pulled it (engine running) it tased Me pretty good so I will be ordering a new coil for the lower cylinder.
2- I don't know if this is related but the forward/reverse will engage and run when the rpm's are low and as soon as I increase them it will let go then if I lower the rpm's again and it will re-engage and run fine until I increase the rpm's, I played with the cable and it really looks like it is moving as far as it should I fine tuned it to make it so and yet it does the same thing. I have taken the gear case apart in the past to re-align the fork that moves the clutch-dog and everything looks really clean and in good shape to I just put all new seals in it and a new lock ring.

What are Your thoughts on this?


Thanks.

Re: 84 Evinrude 35hp ?

Is it actually coming out of gear or is the prop slipping on the hub?

Re: 84 Evinrude 35hp ?

I suspect #1 and #2 are the same thing. It is coming out of gear, rotating half a revolution, and slamming back into gear. Many people mistake it for a miss. Other people think they ran over a gator.

Usually caused by a worn out clutch dog and forward gear.

Re: 84 Evinrude 35hp ?

The lower coil really is weak I think and it showed when I pulled the wire from it, the prop is fine although I thought that was the problem at first. It will engage at low rpm but when I increase the rpms the engine will rev up very fast and Not move then I throttle down and it re-engages. How do I know if it is the dog and gear? It really didn't look bad to Me when I had it apart but then again I can be wrong.

Thanks.

Sorry I misread your post. Deleted my comment.

Really sounds like a spun prop hub; mark the hub and the prop with a straight line, then run motor until it "slips" and revs up. Look at the lines; if not straight still then its re-hub time at a prop shop. Good luck

Re: 84 Evinrude 35hp ?

That is what I thought but it just feels like it is jumping and yet the shifter moves as far as it should, I marked the arm on the side of the outboard with the cable link disconnected and then moved the cable to the forward and reverse position recording where it was sitting and it was aligned with the shifter arm.

I really hope You're right, I will do what You say and mark the hub and prop then rev it up and see what it shows after. In case this is the problem, is there a way to rebuild the prop hub or do I need a new propeller?

Thanks.

Any prop shop can do the job; this is not a DIY job takes equipment most of us do not have. There should be plenty of prop repair shops up in MD. Good luck

I found one on ebay but I can't tell if it is the same as mine, it says "10.5 X 11 Aluminum Prop Johnson - Evinrude 20-35HP", I also found a shop near Me that might repair it, not sure if they do this type of work what is the best approach?

Thanks.

Re: 84 Evinrude 35hp ?

So, have you determined if it is slipping or not? That is #1 approach. #2, after you have determined that is the case, you need to find out what size prop you have. Blindly buying just any ol' size isn't a good idea. Look at yours right around the hub area to see if it is marked.

Now that you have all that information, you can go shopping. Is your prop in otherwise good condition (worth rebuilding)? If so, having it done is generally better than buying a used one that may or may not be good. Remember, a good prop shop can make it like new. If it isn't worth rebuilding, look for a new one. iboats is a good place to start.

Re: 84 Evinrude 35hp ?

I have My boat at the farm right now and I'm at least an hour away, I will do as You described, I'm not going to buy a prop until I'm certain that is the problem. Mine is in good condition overall but it looks like it hit something at some point and it was straightened out, all the blades are at the same angle.
I found a shop near Me I can take the prop to them if I need to, I do remember the inner hub is made out of plastic, are they all like this? Maybe if the teeth were aluminum and it had some sort of rubber/polyurethane insulator between the prop and the hub.

Re: 84 Evinrude 35hp ?

Well I pulled the prop out and looking at it seems fine to Me but I did not test it in the water after the previous episode, the front reads "Michigan Wheel 012056A 10X13" the inside counts 14 teeth. I took it to a local shop and the mech said that by the looks it is spinning but also said what You guys proposed already to mark it with a chisel and test it in the water I asked if He could just install a new hub for Me and the answer was buy a new one, they don't bother with aluminum props only SS bc by the time they put a new one it will be $75 and I can buyb a new one for $90 or less. So, I searched in this web site and found a few options, maybe You guys can help Me choose.

Here is the link " 13” Pitch Evinrude Outboard Boat Propellers 35 HP 1979 - 1983 2-Cyl. - iboats " I was thinking to buy the lowest cost prop for this motor and I see the solas amita 3 blade and 4 blade, mine is a 3 blade what difference would it make if I get the 4 blade prop?

Here are some pics of what I got.
Thanks.

Re: 84 Evinrude 35hp ?

If the engine and boat performed satisfactorily before then I would be inclined to stick with the same prop size and blade number you have. Just my opinion; good luck.

I wouldn't know bc I had to rebuild it almost as soon as I got it, the engine had a lower piston ring broken off and smashed on the head. This first time in the water after the rebuild it did move for a little while with this propeller and it was fast but I don't know what fast is with this boat yet, after that it started to fail as I described above in this thread and I can only go forward or reverse at slow rpm's.

Thanks.

Re: 84 Evinrude 35hp ?

Ok I locked the hub part of the prop and turned it by hand on the prop side and it moves almost easy, when it was still on the motor it would all turn even with the motor in gear but I removed it and tried this now and it appears it was the culprit all along. Should it be this easy or is it that the prop was really just done?

I will order a new prop now, My question now is, I looked it up on this web site and there are props for evinrude 35hp with exhaust through the prop up until 83 and mine is a 84 is that still OK? There is a solas in the link I posted above that appears to work for evinrude up to 83.
Here is a link to it http://boatpropellers.iboats.com/Ev...1-101-13_Propeller/38/6166/?*******=180943884
Thanks.

Re: 84 Evinrude 35hp ?

I don't know why iboats' listing cuts off at 1983. However, I looked up that Solas prop on another website and it says it fits both '83 and '84. But iboats price is better.

Re: 84 Evinrude 35hp ?

Hello again,

I'm the guy that sent you the photos of my 84 35Hp a few weeks ago. I just wanted to get my 2 cents in on this one.

A few years ago I bought a Michigan Wheel Vortex and I like it. The hub and the prop are separate pieces, you can replace one without the other. It costs a bit more up front but you can replace each one cheaper than buying the whole prop. So if you spin the hub you replace it and it's cheaper than getting one replaced elsewhere. If you bang up the prop you can have it fixed if it isn't too bad, or you buy a new prop and keep the hub and again it's cheaper than buying the whole thing. Another advantage is if you ever add weight to your boat you can change just the prop and sell the old one ebay.

Since you>re not sure about the dia. and pitch this might interest you. I assume you know how to tell when you have the right prop. It's by RPM, at WOT and plained out the engine should be running at whatever it max RPM by the book.

Wherever I bought mine I ask them about pitch, they said if I bought the wrong one I could send it back and change it for a different one, and I had send two back before we got it right. If you're interested I'll dig out the receipt tomorrow. Just let me know.

Good luck.

Re: 84 Evinrude 35hp ?

Hello thank You again for the photos they are great guidance still for Me. The prop I have says "Michigan Wheel 012056A 10X13", are You saying I can get a hub for this one separately? Please let Me know. The prop is in good shape but the hub spun and I pulled it out, the brass piece is fine but the rubber insulator is all gone so now I have the prop in good shape and brass hub also in good shape just the rubber that links the two is gone.

Thanks.

He is talking about this kind. I don't think that is what you have now. In fact, I don't think it was even invented yet. But it is a good idea which I'd probably go for.
