Specs At A Glance

Good To Know

Q: Does this crankshaft fit every Yamaha 90HP outboard? A: It is built for three-cylinder 75 through 90 horsepower models, but fitment can vary by year and serial number. Confirm your engine code and part number before ordering.

Q: Are bearings included with this crankshaft? A: Bearings are not included, so plan to source main and rod bearings separately for a complete rebuild. Check journal sizing with your machinist during assembly.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
