[QUOTE="Howard, post: 261498, member: 3395"] I have a mid 90's 15HP Evinrude on a 1648 Jon. It has been on my boat for a year now. I have put about 15 gallons of fuel through it so far with no problems. It pushes it about 15 MPH and I have been very happy. Yesterday, going across the lake in 40 foot of water, full throttle, it suddenly came a quick drop in speed as the RPM stayed steady. I was able to navigate it to the boat ramp at low speed but each time I would try to full throttle it would seemed to "cavitate" on me. Since I know that the motor cavitation plate is set correctly for this boat, what is going on?? I have read once that a prop could spin out?? My question is what is the best way to check for this, or anything else I can check, thanks in advance [/QUOTE]
