Exhaust Muffler Kit
This muffler, designed for use on all V-8 engines with Plus Power exhaust systems (4 in.,
7 degrees downward outlets), requires the installation of 1-1/4 in. (32 mm) exhaust elbow
risers, which are included in the kit.
IMPORTANT: If a thru-transom exhaust kit other than the one from Mercury Marine
is used, the exhaust kit must be equipped with internal shutters and external flap-
pers.
CAUTION
It is the responsibility of the boat manufacturer or installing dealer to properly
locate the engine and install exhaust system. Improper installation may allow water
to enter the exhaust manifolds and combustion chambers, and severely damage
the engine. Damage caused by water in the engine will not be covered by
MerCruiser Warranty, unless this damage is the result of defective part(s).
