I know, Probably a completely rookie question... In changing the water impeller on an 02 Sanger V210. It is in the external "Seawater Pump" as the manual calls it. Last weekend the pump froze up completely. In taking it apart, the impeller looks fine, but it was definitely the impeller that was binding. So my stupid question is....should it be greased or something? Allowing the blades to spin smoother within the housing?
