REDUCE

INTERIOR / EXTERIOR
FLAPS
No internal flapper, including this one, is designed to make a
water tight seal. That is not it’s purpose. It’s purpose is
only to stop the backwash surge. It is the installer’s
responsibility to determine the relationship between the
engine height and the water line to prevent water leakage into
the exhaust. If the engine is mounted too low, water will leak
into the exhaust ports and cause severe damage.
