Coupler?

[wantacat]

I replaced mine, I was hunting a vib. and a cavitation problem. Are you having some problems ?
Yes, actually I think its my coupler. My boat does go anywhere under throttle. It will go forward and reverse but when given some gas the motor just revs up and the smell of burnt rubber comes from the motor along with some smoke.

Yup I would say it's the coupler. Have fun.
