I have a 1984 mastercraft boat and i had to replace the impeller in pump and now i cant get it to prime?

Question

so the boat will idle but starts getting hot because the water is not getting to motor. does anyone know what to do

Answer 1

id check the impeller

id make sure the impeller housing was not broken and the gasket is good. should have been replaced when you installed the impeller, depending on engine usually hasto be unless the housing is stainless steel.

then id make sure it hadnt seized. if you replaced it due to the old one being broken or siezed id check the housing make sure it was free of burnt pieces remaining.

id make sure the inlets wer not blocked.

and make sure the woodruff key is located in the impeller on the shaft. otherwise the shaft will spin but will turn inside the impeller. if you didnt check it may have falled out when you took the old one out.

other than that, dunno. but impellers dont need priming.
