I Have/had a rule 1100 that came with boat and it does a good job with the 30 gal well. After 4 seasons the shaft at the impeller broke off and looks rusty too. It ws gauranteed for 3 years so got 3.5 years out of it. Any recomendations on up grades, I see mixed reviews on about all bait well pumps. The rule does have an easy change out motor replacement, as most brands do, kinda lends to the idea I'll be replacing these huh ?
