you have to recut your exhaust and raise your motor just a little thats why I bought a 2'' shortie. the standard box is a bolt on. most single v hulls work good with the 3 ''box when your prop shaft is a round 7 to 6 '' below the v. hope that helps some so after the box is on the prop shalf would be about 3'' to 4''.mine is at 5 1/2'' no box and I pick up 4 or 5 mph. so with the 3''box you should see 4 to 8 mph pick up and thats a great price too. and is easier on your coupler than the stellings. good luck.
