For full disclosure it was my mechanic and not me that removed them. He did say that some new boats today don't use them and they weren't necessary. Is that not accurate? Should I be considering putting new ones in?The intention of those flappers is to keep sloshing water from entering the manifold (think of them as a one way valve). You may want to conciser replacing vs removing entirely.
