I have a 25 hp gas Kubota WG750 and a 1572 that runs great, but thinking of doing an engine swap. I know the water pump is about 1 1/2" higher but I don't think that should be an issue being towards the rear with the radiator up front. I was also thinking of using a electric fan for the radiator as the engine has a 30 amp alternator on it. Is there anything else I may need to know before jumping in?
