4 Cyl. Engines
This replaces
MerCruiser p/n 12632A6 which is a triangular engine coupler. They are used on some
late model 4 cylinder engines. Now they have a
tube attached with a grease fitting so you can lubricate the drive shaft splines
without removing the outdrive as long as your old drive shaft has the extra o-ring
grove cut into it to keep the grease from coming out around the end of the shaft instead of
going through to the splines. It is always best
to remove your old coupler before ordering a replacement to make sure you're
ordering the correct coupler.
