Corsa Marine 4" Inline Exhaust Flapper

These are a very good quality inline flapper and made to go inside of a 4" exhaust hose. Everyone with thru hull exhaust should have these. All engines should have 2 methods of preventing water from entering the engine exhaust. These are standard equipment on all Hornets with thru hull exhaust. These are to be used in conjunction with tips with built in flappers. They are all stainless steel with a high temp rubber coated flapper that makes them quite and brvides a better seal.

They are installed by sliding into your exhaust hose upstream of the thru hull and then just put one hose clamp in the outside of the hose to hold in place.

These are imperative on boats that sit a little low in the transom and get high water when coming off of plane.

These are a universal fit for any 4" exhaust hose but changes in our design have left us with a few extra sets of these

They are sold by the pair

I just listed them and have a few sets. No Reserve.

If you have thru Hull exhaust I can not recommend these enough
