    Default replace Y pipe 3" (exhaust pipe)

    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.

    ranfot,

    There looks to be quite a number of them on Ebay, not sure if these are 3", you could ask the sellers, if not do a search. http://www.ebay.com/itm/Mercruiser-E...f0bb0e&vxp=mtr

    Thank you. I was looking by new part # which did not give me any results, but now I understand that I should have checked by using different keywords. Again, thanks a lot!
