correct ex flappers

[blando]

I have 1995 merc 4.3 with 2 piece elbow exhaust manifold that i need flappers for. Here's the thing , I've read several discussions and the sticky, but am still not 100% which ones are correct. I have the 2 piece elbow /manifold with the one piece batwing exhaust, see pics. I don't know if this is original or upgraded. Can anyone tell by the pics what i have and need. Couldn't find any numbers on the batwing pipes. My engines a replacement(1998) so thats no help.

Did you for sure have a 1 Piece system that went to a 2 Piece system at some point of time as you the owner?

Maybe having all 3 (or 4?) of you serial numbers to the engine, drive, transom assembly may help some here too....(Old engine too for 4th)...

NO. It is NOT for sure originally the one piece riser/elbow, manifold. I dont know if it was originally a one piece elbow /riser manifold. All i know is it is now and may have been from factory a 2 piece riser elbow/ manifold with one piece batwing pipe. I dont have old engine number(although maybe on title, now that i think of it ).
Herein lies the question.

im thinking since the holes are round its these?

Add to Cart:

Exhaust Water Shutter Flapper for 4 Inch Y pipe used on Mercruiser.

Fits into the "Y" Pipe on most V-6 & V-8 engines to help prevent water from backing into the manifold and engine

If your flapper currently has round grommets that hold it in, and a 4 inch Y-Pipe, then this is the correct flapper
If your current flapper is held in with squaregrommets, then you can remove the round exhaust ring and use the included grommets.

• Does Not Fit 4.3 Engines Originally Equipped with the 1 Piece Exhaust Manifold

Yes this would be the correct one to buy as you do have the round design in the Y-Pipe after re-looking over the photos better/closer....Sometimes when the hole starts to wear out it can form a different view perspective which i thought I seeing a square design on one side...But upon thinking back, 'The square design generally has a cut-out slot at the top/tip of the Y-pipe so I was trying to make sure you didn't seem to have anything different going on there was all or if maybe you had a 1 piece into 2 kit like this on the left, https://bpi.ebasicpower.com/shop/in..._in_description=1&categories_id=&inc_subcat=1 .

Hope this helped some, Good luck.
