Just got a call from a buddy who was on the water pulling a skier, boat overrevved and would only pull at idle speed from that point on, made it back to trailer fine but only at idle speed, reverse works fine, no grinding or unusual noises, V6 w/alpha drive. 90's model cookie cutter , Im going to get enlisted to figure this out and I dont know shit about stern drives (jet guy) can one of you guys give me a starting point for this problem? thanks ......
