Water coming into bilge

[Bondo]

Exhaust bellows is always wet. IDK off the top of my head what/if any sealers are supposed to be used on the y pipe...

Ayuh,..... I paint it all with Perfect Seal,.... bolts especially,.....

I grabbed a tube sikaflex 291. How about using that bondo or should I grab a certain kind of permaseal

Perfect seal

 

[Jakem]

Will the sikaflex do the job to seal the y pipe?

 

[Lou C]

Perfect Seal, Evinrude gasket sealer or Permatex Aviation are all good for that application….

If motor is out, I'd examine for corrosion on transom metal. Older Alphas are easier to find than Bravos. You may consider finding a freshwater used one to replace yours if too much corrosion or you have a hairline crack. I'd try to resurface transom pipe connection and y-pipe surface. I know some will disagree, but on older y-pipes that are not so perfect anymore, I'd 5200 o ring in place, while still not cured and install pipe. Just added protection... Fill bilge area with water up to input shaft and check for leaks on other side. Most all of us have been where you are. Good luck!

There really is little to no corrosion anywere. I will reseal with perfect seal and test it out

Not to make a big fuss, couldn't pay me to use 5200 on anything that might ever need taken apart. Almost anything but 5200 is suitable.

What I have done is a nice even coat of sikaflex. Glued O rings in. So shall I install it...or scrape it off and use the permanent aviation I bought

I agree, but when all else fails, punt, "danger close" or 5200. Then, use a bigger hammer. LOL

After resealing everything there is no water coming out of the y pipe with the hose running into down pipes

4200 is underappreciated

I used aviation sealant...some stickey

Just out of curiosity, did you replace shifter boot and clamp? This communication has been too long for my old brain to sift through. You said you replaced bellows but did that include shifter boot?

 

[Jakem]

Changing it today.

 

[Jakem]

However the first time I ran the hose into down pipes it was leaking out the y pipe.

 

[Jakem]

Just to confirm what I think I already know the answer....filled the bilge with water...water coming out of exhaust..so I'm assuming y pipe connector
