So I'm thinking about buying a V150TLRZ it was on rental boat. (tri-toon) The guy doesn't know how many hours it has on it. So my question how can I find out the hours before I buy this thing. And can anybody give me some details about this model motor.(length shaft,efi,hpdi,cabs,etc) I plan on checking compression in it. Are these good motors without a history of problems?
