Went to the lake yesterday with my 98 yamaha 60hp. Idle speed was fine but at full throttle only seemed to be getting about half speed. I have replaced the cdi box, fuel tank, fuel line and filter cleaned carbs and replaced plugs. Ran the boat a month ago and had no issues I pulled skiers with it all day. So just trying to figure out if anyone knows what could have happend to it in a months time in dry storage.
