Yea I bought the replacement flapper kit. I believe u can change them in the boat I just happened to be replacing my tips as well.

as long as the flap hinge pins are slip out replacement in place will be doable. some are welded in. then they gotta be surgically removed and holes for new pins drilled.

Since I have no comparison of the two, would you say the Teague replacement ones are heavier duty than what you had before? Or were yours "missing" also? Lol

Hopefully they aren't welded in that might change my plans lol


Does anyone know if the Silent Choice "Y" pipe flappers discussed above (post #12) have any "upgrade" options available or am I buying those from Mercury?

I had the flapper that where metal with the small rubber strip on each end. The rubber kept coming off. The Teague one wont have that problem. And there not welded in so if I replace to replace one one day should be easy.

The replacement flappers from Merc are of a newer design. An all 1 piece snap in unit. They seem to last, at least mine have.

Sweet! I haven't looked at mine yet but I will make sure to get updated ones!

Does anyone have a hookup for Merc parts?

I have the merc tips that allow you to change the flapper from the outside of the boat. I got tired of the noise and took them out. Now I just run external flappers. They might not look great but you can inspect them easily, and they are quiet. My boat sits pretty low in the back and my transom is black, so they are barely noticeable.

Those metal ones must be pretty noisy... Don't think I would want more noises to worry about so I'm with you on that one. I have the external flappers too and I sure agree they are fugly! When I hit the big leagues like HyFive (jealous lol) I'm getting these to cure that issue:

Be sure that those will work on your boat. Mine flip up against bottom side of swim platform. Looks like those will hit at the hinge flange, or if anything rattle against the swim platform and be noisier and wear into the gel. That is if your tips are at the very top like mine are. Not sure if there is a different height between our yr 32's.

Worth a look see. Those would not fit, let alone open on my boat. I don't see the issue with the rubber outside ones, only visible when on the trailer
