Hey guys I just got a new boat it has a 2007 115 optimax on it and a 15 hp four stroke merc kicker. The previous owner had a portable gas tank on the back of the boat for the kicker. I don't want that there my old boat never had that so the question is can I just T off the main line for the main motor with two ball valves one for each after the T ? or will I have issues. Does the main motor being a fuel injection come into play? thanks !
