I see no reason why you cannot use the 12 degree box. My Cole has a 7 degree strut and a 12 degree V drive. Always been that way. Just mount the V drive to align proper to the strut/propshaft.
If you have to raise the motor slightly for alignment to the V drive so be it. Drivelines need slight angles to work universal joints properly anyway.
Is that what you need to know?
Thanks Fiat48, this is what I was thinking but just wanted to bounce it off all the guys that talk about boat setup here on the boards but it seems they have all lost their memory or I am not in the IN crowd :idea:. Also was just wondering if this is the case for setup why everybody wants a 10* and they don't just put in a 12*
