Took my boat out yesterday if I run it up about 90 mph and let off the gas to quik the drive make some real bad noises. I would think that it's the water presure around the prop . Do they make a slip cluch for a bravo 1 like they do for drag boats with a V drive?

A cone clutch ( bravo drives)will unlock when the output shaft ( propshaft) speed is faster than the input shaft speed....it's just the nature of the design.


The noise might be coming from the shift fork and cone
rattling when disengaged when the shift fork mechanism
is in an engaged position......either way, I would avoid rapid disengagements, and re-engagements on bravo drives if you want them to last.
