Re: 1959 evinrude 35hp water around carb have pics "problem found need help to fix"

ok guys with all you alls help I am 300% sure we have found the problem. Ok remember i said bottom cylinder was getting water well so was the top it was just to high up that it didnt get much. i took off the exhaust gasket (broke two bolts lol im getting good at rethreading with this motor) and i was like what the &$^& its got a pretty good seal. so anyways im going to replace the gasket so i brought the cover inside to clean it up good before putting it back together and look what i found. that hole does not get covered with a gasket and does not butt up the the power head, its facing right at my bottom cyclined and spraying water at it. im really glad i found this before things got worse i was getting ready to sell it. i bought this motor for 150 and he said it ran fine i bet he knew something was wrong. ok now how should i fix this hole that has eatten thru there, copper gasket maker, jb weld, im acually a welder but i dont have a tig welder to spot it with. Let me know what you all think and how i should fix it. AGAIN THANK YOU SO MUCH EVERYONE FOR YOUR HELP REALLY.....hope im going to be on the lake soon.

If it's the stainless one, I'd try to find a way to weld it. If it's one of the aluminum ones, then I don't know.

could try to use oxy/acet with aluminum rod.

Relax. Unless there is an obvious leak somewhere, spraying obvious water around, I would say it is nothing more than condensation. The intake manifold area of an engine gets cold for the same reason that an air conditioner gets cold. In warm humid air that cold metal sweats for the same reason that a glass of ice tea sweats. Old car carburetors would actually freeze ice under certain conditions. Icing on old airplane carburetors was a major concern. Anybody around here remember that far back? Dang, I'm getting old.

But all this has nothing to do with water in the cylinder. That is a different topic.

And the goop running out the drain hole in the lower unit is normal. There should be dozens of threads here on that subject, if you care to do a search.

wasnt the carb icing cause they used water/alcohol injection? meh dang im too young to know these things.

That was an all too common problem with the aluminum plates. That is why they changed to stainless ones. My suggestion is that you get a stainless plate and be done with it. The part number is 304761 and is still available, but the price is pretty dear. I suggest you post a free want ad at www.aomci.org and see if you can scare up a used one. Nothing goes wrong with the stainless ones, so used is just as good. They were used on tons of 33, 35, and 40hp motors. Except the 40hp with the hot-air choke.

The gaskets are 304762.

Ok did a compression test you all ready to be puzzled cause i am. Remember that the bottom cyclinder is the one taking on water and the top is the one firing. ok top cyclinder "good one" 65 and bottom one with water intake 116 whats the deal with that i thought it was going to be the other way around. I did both of them the same choke off and other spark plug out. Can this motor be saved or should i try and get another block for it?

If you have 65 psi in a cylinder its time for a rebuild or at least re-ring, anything under 100 is not so good. Also if there off more than 10% your going to have a tough time getting it to run right. IMO

yeah i know ive been reading a couple of post that say if its around 65 on one to try to decarb the motor and it might loosen the rings back out and bring the compression back up. im hoping this will work.
