thinking of stepping up the hp on my boat. what do i need to do for a reliable drive? i have a blown 700hp mtr now with a 04 xr drive with the sportmaster lower, and have had no problems. thinking of pushing the 850-900hp mark.

Bmax, Arneson, IMCO SCX. The least expensice option would be the Bmax and then the SCX followed by the Arneson.
All have their pros & cons. I think the Bmax is the most "bolt-on" friendly of the three.

700hp... did you turn up the boost?

yes. im at about 8lbs with a superchiller

Cool, what did that do speed wise? How high did the super chiller raise everything? I see your considering going another direction on the next power upgrade. I'd like first crack @ the 256 if you do.

I agree, with the word RELIABLE in mind don't consider any Bravo based drive unless you like working on them although I read that All American drive service was giving 2 year warranty's, not sure what power level THAT is at though, Smitty

where you at in colorado? where do you usually boat at? im still trying to figure out what im gonna do. i do know the 256 is gone. hopefully this fall

Colorado Springs. We'll be @ Merideth this weekend & most Holidays. Lake Pueblo & some other smaller skiing lakes. U?
