The outboard is only running at about 1/2 throttle smoothly and any more it hesitates/misses as shown in the video where 1/2 throttle is the max speed I can go. The boat can get on plane and that's about it.
Engine is Yamaha DETO (European model?) 50HP 1984 or 1985 model
Compression is 120-120-120 with spark on all 3 cylinders.
Plugs were just replaced when this first happened, still look good last night. I have done three trips out like this to empty the fuel if it was bad gas but I use ethanol free gas and it never sits long.
Any suggestions of what to look at? or what other info is needed? Even describing the symptoms I may be off but the sound in the video is the problem. I will replace the fuel water separator tomorrow evening as I still need to buy it.
Thank you for any ideas and help!
In the video you can hear the sound of the motor when I accelerate change to the problem hesitation/missing. This is what needs solved. (skip ahead to 20 seconds)
