What is this adjustment knob on water pump?

Post by jim.eakin » Mon Jun 17, 2019 5:14 pm

I'm getting a KBL up and running. I noticed an adjustment knob on the water pump. I've read quite a few posts here and never saw a mention about it.

What does it do and how should it be adjusted?

Hi Jim, that is a grease cup. If you unscrew that cap, you keep it packed with water pump grease and turn it on a few threads. Before you go out for a day of boating, you tighten the cup a turn to push a little grease into the pump to keep it lubed.
Boats are to be made of wood, otherwise, God would have grown fiberglass trees.

Do be sure to use a water pump grease as it doesn't congeal and wash away as fast as regular axle type grease. A greased pump will prime quicker too.
