My Hurricane deck boat has a 4.3 v-6 with a Yamaha sterndrive on it. No one in my town/area will work on the out drive. It needs to be resealed/new bellows,etc installed. Is it possible to switch it out for another make of outdrive? Can I do it myself,Iv'e never done an outdrive. Boat is decent,engine is fine..hate to throw it away and start over..any suggestions?
