    2003 Yamaha F60 carb question

    I checked the pilot screw for each cylinder. # turns out from all the way in: #1: 1 3/4 #2: 1 3/4 #3: 1 5/6 #4: 2 1/8 I was hoping to find that #2 was dramatically different, but wasn't. The new #2 plug now appears black despite hardly any time running.

    2003 Yamaha F60 carb question

    I have been fighting with this motor (F60TLRB) because it has no power under load. Ran fine in the past. Specific question is about my carb #2. I ran in the water under load with each spark plug disconnected one at a time. There was a noticeable difference when each plug was unplugged except...

    2002 Yamaha 60 lost power under load

    I ran in the water under load with each spark plug disconnected one at a time. There was a noticeable difference when each plug was unplugged except for when cylinder two was unplugged. When cylinder two was unplugged, it ran about the same as when it was plugged in. This leads me to believe...

    2002 Yamaha 60 lost power under load

    Cleaned the accelerator pump. It had some deposits in it. The plunger moves in with full throttle now. Didn't change anything though.

    2002 Yamaha 60 lost power under load

    I have a 2002 Yamaha 60hp with carbs. It ran well for years until recently when it lost power under load. It will start great and rev normally in neutral. When under load / in gear, it will not rev up and does not have the power to get fully onto plane. It is not an intermittent problem. It...

    Tilt too weak to lift all way up

    I have a 2002 Yamaha 60 hp four stroke. It has been sitting for some time. Tilt motor spins and will lift motor half way, but will not lift all the way up. I have used the release valve and raised the motor all the way up. The fluid level was full (and have verified it still is / refilled.)...
