Watch out smacking the throttle to quick, stuff goes boom really fast.

we are spinning in. Over 100mph, it needs to be spinning in otherwise it starts chine walking. The slower speed hulls (90mph and under) work best spinning out usually.

Well, after a solid day of running hard at a poker run, i blew another BMAX. Funny thing was, it was when i was giving the boat throttle to load it on the trailer. No more than 1500 rpm. No damage to the prop, like it would have struck something. Im killing these drives left and right. Any help, info, ideas, or know where some BMAX parts are at so i can carry spares. Also, is having a 1.36 ratio making these drives more prone to failure. Any help would be greatly appreciated.

We have a rebuilt form B max lower if you need one. It was one of our customers spares, he has sold his BT.
