Installation
IMPORTANT: When installing intake manifold gaskets, in next step, observe the
following:
•
•
Be sure to install gasket with marked side up. Both gaskets are identical.
On engines with 2 barrel carburetor, remove metal insert from manifold gasket to
be used on starboard (right) cylinder head to provide clearance for heat pipe on
intake manifold.
•
All Mercury MerCruiser V-6 GM engines that have “automatic” carburetor chokes
must use an intake gasket that has an opening for the exhaust crossover port in
the intake manifold. Without this opening the “automatic” carburetor choke will
not operate properly. The choke will remain ON longer causing rough engine op-
eration and wasted fuel.
