    Yes, you will have to pull the power head. It is the shifter assembly that makes that necessary. When you do, that is the time to replace the impeller so you have a nice new dependable one.

    Also, there are two parts under the power head that will need replacing, part numbers 303347 Lower Bearing Seal to Drive Shaft ‘O’ Ring, and 303355 Drive Shaft to Crankcase Gasket.

    Also, this is the time to replace the Shiftlever ‘O’ ring 303191.

    Last but not least is a new Power Head Base Gasket 303467.
