i have a 95 tracker pro 18 jet with the 90 sport jet, i picked up the boat cheap with a blown engine, i rebuilt it last spring with 3 new .020 over vertex pistons, gaskets/seals. the engine runs great now and it gets around quite nicely. it pushes the boat along at about 28 mph and its all she has. my question is can a 175 hp sport jet engine and its drive system be swapped into the existing mounting that has the sport jet 90 set up in it? just trying to see if its a possible project. i can get a jazz jet boat stupid cheap with the 175 sport jet set up to make that happen. otherwise i would just look for a tracker boat with the 175 sport jet
