I need to replace the shutters in the y-pipe for the thru prop exhaust. I'd be damned if i can even find the y-pipe on the parts look up on the BAM website. Anyone help me out with either a p/n or help on where to find it on the parts diagrams. 1996 502mpi. w/ bravo.

This should work.

I believe is the part #

yup, thanks guys........

Well, i got these, ended up not being correct. They are bigger than my y-pipe opening, plus, the holes are round, and dont use the little square holders on the end. Back to the drawing board.

I can not find the " exhaust system" as you pulled up anywhere.

Look under your year of engine in the parts area, Then look it up under the exhaust system area, but this should be your link.http://www.mercruiserparts.com/Show_...EXHAUST+SYSTEM

I don't find anything labeled as exhaust system for my motor. Also, the shutters in that link are not the ones i have. I pulled apart the starboard side last night. Wasn't anything there at at, but there were to little holes front and back of the y-pipe. There is definately no spot for the rectangular rubber plugs. Looks like it's made for a round shaft? This has the impco power plus manifolds, and diverters. The y-pipe wouldn't be theirs as well would it?

That picture look like the old style flappers. When I replaced mine (same as pic) the new didn't use rubber plugs, but a holder that snapped into the holes in the y-pipe.

Yeah, the part that i got looks exaclty the same as the picture. But the holes in my y-pipe are small, like 1/8 inch holes. There wouldn't be any use for the rectangular rubber plugs. Also, the shaft that these shutters are on is also rectangular, not round like the holes in my y-pipe.
