I'm running around 1200 hp through a Bravo coupler (through a BMax drive) and mine lasted 220 hours before the area around the bolt mounting holes (to the flywheel) gave way. After doing a little research, I'm told that is unusual to fail like that. They say that normally the aluminum splines strip out if you get airborne and back in the water still under full power. I rarely run in that rough of water, so I didn't have that problem. I'm going to double drill the mounting holes (12 instead of 6) to see if that helps prevent my problem.

chris , sorry for delay will call you on monday.
thnx for help
-can you ship international?

I just had a first hand experience how strong those aluminum splines are. Had a customer apparently back into something. He twisted the yoke off at the coupler and twisted splines on every shaft in the outdrive! But the coupler stayed in tact...hmmmmm.

Unreal! Now that's some serious R&D/testing!:D
