Yamaha Pro V 150 surging

FlagetFlaget Posts: 8 Greenhorn
My 1989 Yamaha Pro V 150 has been running like the day I bought it until today. Started morning running great. Later in the day motor began surging on take off and on plane. Then it regain all it's power for a few seconds and then surge back and forth, surging between 2 and 3 hundred RPM (28, 29, 30, 29 30 28 etc.). Fuel is fresh (ethanol free fuel only) Spark plugs are about 2 years old but have only about 25 hours. Fuel filter? Any suggestions as to what the issue could be? Thanks in advance. HJ
