engine 2005 496 mag ho +raylar kit/ 530 hp / bravo X
I have upgraded the engine with raylar kit this winteren wonder switching underwater case for a shorter unit but is unsure whether it will give some good effect on boat speed and features.
need advice or what I should choose 1,2,3 inches shorter or hvat ever will be the right choice?

I have used propeller bravo 26 any proposal for a new propeller has 100 hp more now

First thing you need to do is determine your drive depth or x dimension. If your drive is really deep a shortie may help.
