Aloha to all<br />Just bought a used Twin Vee 17' with this motor it's starting to heat at trolling speed I think the impeller need replace I also have the clymer book it says to remove the prop. Is it nessary to remove it, to drop the gearcase and overhaul the water pump? <br />Mahalo = thank you <br />P.S. I also need a good parts source for both boat & motor as its poor for both here on the big island of hawaii
