I think it would help alot in my situation. With a drive temp gage installed I found that I could get the oil in the drive VERY hot, when running hard. If the Drew Marine system keeps the oil temp low all the time, then it 'should ' help with gear and seal life right?

that kit actuall does drop oil temps most effectively compared to typical drive shower's. and along with a good synthetic gear oil like mobil 1's there would be a significant term life expectancy.

Doesn't the Bmax have water cooling passages ?

Yes, the whole case is encapsulated like a manifold almost and exits thru the top cap.

I didn't know it exited throught the top cap! Does the drive not supply to the engine?? Or does it do both?

Both...

There is the regular pickup that supplies the engine, then there is another pickup just above the bullet which supplies the water to the drive. The water exits via two holes in the upper cap.

not good news. You pulled 5 boats w/ 11 broken drives? was one a triple?
With hard core comments like that some details would be nice.
And you went through 12 drives w/ one boat alone?
What kind of power were you running ?
Did you have any gimble failures? And what gimbles were you using?
And what kind of pwr were the NorTechs running?
Is it true that the bmax is rated for 900 and the XR is around 550?
