The boat is a rear mount through a gearbox to a v drive you loose a bit of hp with the gearbox but i think that it will be ok for a ski boat.

The boat original had 13.1 compression but the chap i bought it of had it rebored and had put it down to about 10.1 so i may loose a bit of hp there will be enough left.I dont know how far it will go untill it gets to Rons house next week but it will be resored properly.
