We have 2 Crusaders, both have Jabsco 42730-0000 raw-water pumps on them. Have had nothing but trouble with both pumps. Main problem is that both have single-belt pullies, and we can never keep enough tension on the belts to keep them from slipping and sometimes smoking. I have taken both pumps apart, and they turn very easy by hand with the impellers removed. Of course there is considerable resistance with the impellers installed, I think it is too much for the single belts to handle. The pumps sit on metal brackets, and rely on sliding the pump to tension the belt. A pic would speak volumes, I'll try and take one tomorrow. If anyone has any insight or ideas as to how to keep the belts from slipping that would be great. I have had them tight to the point where there is little deflection, and the belts still slip on the pump pulleys.
Thank you,
