Hi all,

I have old and leaking Y exhaust pipe on one of the engines on my 87 Sea Ray Sundancer dual 4.3 262 V6 with MR outdrives.

I am unable to find 3" pipe part #99877A9 anywhere.
Question: can I use 4" pipe instead and maybe some sort of adapter? any help will be appreciated.

Re: replace Y pipe 3"

The 4" Y will bolt on, but you will have to change the exhaust elbows (Risers) and along with all the other items between the elbows and the Y pipe.
