Need some advice, I am in the middle of a complete rerig of my 96 STV Mod VP and need to know the best prop shaft height for Drags and some top end. The boat came with a 20" motor that I am changing to a 15", I have cut the transom down and will be bolting motor directly to transom. The boat will be used for normal use and will also be used for drag racing and some top end. I will be running a mod 260 (port work SVS brucato PCU) with a 150hp shot of nitrox and a Bob's coned 200 gearcase. I want the best performance to be for drags with top end being 2nd. As I am bolting directly to the transom I only have one good shot at this, any ideas.
