What drive coupler do you guys with big power and Bravo style drives use?

Is there any other than the Merc Hi-Perf one? What about a spring loaded one like the ones that are used with trannys?

There must be some plates that fit Bravo's that's not the rubber ones, right???

there are some aftermarket couplers out there for hi perf. stay with the rubber couplers, they save all the shafts in the drive, there are a lot of boats out there running 1000 hp+ with the rubber couplers and hold up fine.

I used a Merc HD long snout steel coupler when I replaced the coupler on my Pantera.

Its is merc part #861523A7

I run what Griff mentioned and I have about the same HP as you do.

I'm running the merc long snout hp,its been in my boat for 5 years,2 w/750 hp,2 w/950 hp and the past year with 1057,still looked 90% good last time it was out,I wouldn't buy anything else unless your having problems,Smitty

Not that couplers never break, but everything in the Bravo drive is probably weaker than the coupler. I've seen Alpha boats with bad couplers, I think they fail at random or from manufacturer defects more often than from hp.

Alignment is very crucial, and soft or flexing transoms will eat up any coupler.

Good point, I didn't think of that.

Alignment and lack of grease are the main reasons a coupler fails. The steel snout also is stronger than the aluminum ones.
