Good To Know

Q: Why do watercraft owners block off the oil injection pump? A: Factory oil pumps can fail without warning, leading to severe oil starvation and catastrophic engine failure; pre-mixing ensures consistent lubrication.

Q: Do I need to modify the engine block to install this plate? A: No, this plate mounts directly over the opening left by the removed oil pump using the original mounting holes.

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