Good To Know

Q: Do I need to remove the engine to install this kit? A: No, in most cases the power valve area can be serviced with the engine in the hull once the surrounding components are moved aside. Follow your service manual for the exact procedure.

Q: Should I replace the gaskets any time the power valves come out? A: Yes, gaskets are typically single use, so fitting a fresh kit any time the valves are removed helps prevent leaks. Torque fasteners to spec and inspect for smooth valve travel after reassembly.

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