I have a 1992 Yamaha 40 and untill 2 weeks ago it was running like a dream. Now it runs up to about 35 knots for about 5 minutes, and then drops to 25 knots and will not accellerate any higher at all. It sounds as though it is not revving as highly either. The engine is in fantatsic condition and I was wondering if anybody has experienced any similar problems, and has any solutions.<br /><br />Thanks<br />Andy
