5.7L Flywheel (1986 & Later
Marine Engines, 12" diameter)



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 12" 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.

When 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).

If you have an existing 5.7L engine with an existing 14" flywheel, then you do NOT need this flywheel.

Brand new 5.7L base marine engines ship with a 14" flywheel. (The 14" flywheel may not work in some 5.7L applications because it is too large. It will not fit in the existing bell housing and the existing starter cannot engage the 14" flywheel).

This flywheel is unique to a 5.7L engine. It will only fit and install on a 5.7L engine made from 1986 to present.
