RWB218A – Exhaust Guard Rubber Flap – RWB Marine

RWB218A Exhaust Guard is a large rubber exhaust flap designed to protect marine exhaust outlets from water entry and backflow. This rubber guard fits exhaust sizes between 80mm and 105mm.

Exhaust flaps prevent water from flowing back into the exhaust system when the engine stops. Without a guard, water can enter the exhaust housing. Therefore, replacing worn rubber flaps helps protect the engine from internal damage.

Rubber exhaust guards become hard, cracked, or loose over time. As a result, the flap may not seal correctly. This can allow water to enter the exhaust system, especially when reversing or in rough water. Installing a new flap restores proper protection.

This RWB Marine exhaust guard suits many boats, stern drives, and outboard exhaust outlets using large rubber flap covers. Always check the outlet diameter before installation to ensure correct fitment. Proper size is important for correct sealing.

This part is Old Stock in original packaging and in good unused condition. It is ideal for replacement, restoration, or general marine maintenance work.
