I have fresh water cooling system on my boat and figured it was time to change the pump impellers. I've only owned the boat for one year so I don't know the last time they were changed. I wound up taking my raw water pump (Jabsco) off the engine yesterday as it seemed easier than digging out the back plate and impeller in situ. To my surprise, I was unable to turn the pump by hand. The pump worked fine last fall. Is this normal, or should I assume I need to redo the bearings?
