Good To Know

Q: Can I install this rod with the engine still in the hull? A: No, this connecting rod kit requires the engine to be removed and the crankcase split for proper installation. Q: Does this kit fit both rods in the engine? A: Confirm the quantity needed for your rebuild, as listings may supply one rod or a set depending on the option selected.

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