Good morning,<br /><br />My 1989 60 hp Johnson seeems to be running on two cylinders at high speed. It doesn't plane out like it should There is a definite loss of power. For a short 20 seconds it was fine but went back to current condition. It idles fine. sounds great with high idle using manual lever. I have changed the plugs, put in 15 gallons of new gas to mix with old. looked at spark while running by taking a wire off each cylinder. felt some spark through wire and motor reacted to loss of plug. Any ideas? High speed carb jet or power pack are my next two choices I believe from previous posts.<br />Thanks. Of course this happens on the 4th and ruined my plans to tow the kids tubing.
