I have an 89 yamaha 50 HP that makes an high pitched squealing noise when I first start it up but then goes away, sounds like a belt slipping, but very short intermittent pulses. Any help? I know this is the busiest season for all the experts, so thanks in advance.
I have an 89 Yamaha 50deto that idles fine and shoots out of the hole good, but the last little bit of throttle advancement it hesitates (around 4500 rpm), acts like it is bogging down and will not go any faster.
