Another question for you wise ones, on the little cam for the water pump there are holes that line up but the inner shaft is partly blocked and the outer one there is only a hole on one side, should there be some sort of pin or ball-bearing, cheers
No pin or ball. I believe the holes are there to let water pass through as it goes up and down moving the piston in the pump .
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
