Safer Wholesale carries
virtually every marine flywheel ever used in marine applications. There
are only two flywheel sizes used in GM based marine engines: a 12¾" and
a 14" flywheel (true inboard flywheels are always 14" with the ring
gear on the outside edge of the flywheel). The crank bolt pattern of
each engine (where the flywheel mates on the back crankshaft), is
different for each engine. Simply said, a 14" flywheel from a 4.3L
engine will not fit or bolt on a 5.7L engine, even though they are both 14" in diameter.
ordering a flywheel, first measure your flywheel diameter (most are
14"), identify the YEAR of the engine, then identify your exact engine
(3.0L, 4.3L, 5.7L, etc).CALL 1-866-606-3991

This sterndrive flywheel can also be easily identified by the starter which mounts on the bottom of the engine block.
This flywheel is unique to a 8.1L sterndrive engine. It will only fit and install on 8.1L sterndrive engines made from 2001 to present.
