Air silencer cover

[Rob406]

The paper gasket on my 97 Evinrude 50 air silencer cover began to fall apart around the bolt holes due to fuel and oil. I found small pieces of it that at the bottom of the cover that are likely to get sucked in thru the carburetor. I am wondering if it would be better to use a black RTV, or even no gasket at all? Thoughts?

Myself I would try no gasket at all. If I noticed that it was making an annoying noise from air leaks then RTV. I doubt you will notice any difference with no gasket.

i would never not use the cork gasket! its sealed and calibrated at high speed for your specific set of carbs. RTV seems impossible to get off and of course some could get into the reed area and hang them open i suppose. also the air silencer base has it's own cork gasket. if the outer cover one is bad, you can bet the other should be replaced as that one is really important w. stock jetting

Thanks, I was thinking RTV because the original gasket was glued in place (also difficult to remove) and of course the paper portion was deteriorating and pieces were getting sucked into the carbs. I ran it today with no gasket, seemed fine. There are 3 big 1” holes in the side of the cover anyway. This one i removed happened to be paper, not cork. If i could find a cork one i would run it.

I think your fine without it and if it's running fine it proves it.

It's called an air box(no filter) we called it "the splash box" back in the day. Sound less "throaty" with it on.

I lost my carburetor FACTORY black plastic Air Noise reducer. A 2 stroke is very NOISEY without that part.

yea honestly ive never run one without a gasket, but for example if the whole cover and base was removed, you'd need to go up a couple sizes on the mains or it will 100% run lean. i guess it wont hurt, but again it was calibrated with those holes in mind. just something to think about. the cork gaskets are like $20 all in.
