Check with Dan Gano (link on this site) Tell him what motor you have and what you are looking for. I just ordered a bunch of gaskets for my 57 Evinrude 35 HP.

So I have not had a lot of luck finding the correct base gasket for the OMC 35Hp for my year model. Anyone have a part number?

Would love to get an original parts guide from a closed down shop. The ability to find the right p/n is priceless IMO.

They sure seem to. I went as far as replacing the gasket under the powerhead.

It leaked worse!


If the base gasket is bad tightening the screws will not help much.


Upon inspection the old gasket looked good but I changed it anyway. It was suggested to me that the block and middle unit likely could use some machining as they are probably slightly warped.

I have a RD from 1974, a 40hp, no leakage, not a drop. The problem may have been solved. Of course the super quite lower units would hide such leakage.

There are several places to check for this, first would be what John indicated. Check all the screws under cowl base that go into the power head. They tend to come loose over time. Tightening the screws could correct the problem.

The other place to look is on the back of the power head, the are two compression relief valves with springs, if they are not sealing properly the black oil could be leaking from there and you will see oil on the back of the head. This is a current issue I am having with my 1958 35hp Johnson. This issue requires the head to be removed to correct.

Let us know what you find.

So I was very fortunate to have had the old Evinrude run flawlessly at Arrowhead - I believe we boated over 130 miles that weekend. I say fortunate because I have NEVER worked on this engine before - bought it from a local enthusiast who said it was good to go. That was 7 years ago.

Sooooooo - I saw something like this after I test ran the engine a month ago, and then this is after the ride home from TN. I want to verify anything I should on this engine to keep it running good. Where would you expect this is actually leaking from?

Thanks John! The rubber washers got me through Arrowhead, but I am replacing them ASAP with the correct washers. :)
