The most common problems with circulation pumps are bearings or seal failures indicated by noise, pulley wobble, or leaking at the bottom of the pump.
The pulley is not included. Approved for Saltwater use.
Can be used on standard 240/250 hp right hand engines
The older pumps do not use the two additional newer style mounting holes (not used) so just ignore them for the older applications.
