            Gen II Water Pump Guide Pins

This is MerCruiser p/n 91- 821571A1. These guide pins are used during the reassembly of the water pump.  After placing the gaskets, wear plate and impeller in the lower unit, these pins are then screwed into (2) of the water pump mounting holes and are used to guide the upper stainless steel housing down onto the mounting surface. 

Always remember to put some grease inside of the upper housing and to turn the vertical drive shaft clock-wise when lowering the housing down onto the mounting surface. This will put the correct bend on the impeller.

 

 

 

 

 

These will fit all Alpha One / Generation II drives made from 1991 to Date.
