Lets start by admitting I know less than zero about this motor :) What I do know is that I've had it for about 5 years and it has run like a champ, started on 1 or 2 pulls and ran perfectly, until this fall.
It still starts fine and idles great, the problem starts when I put it in gear, I have no power. I turn the throttle to what should be wide open and it revs to approx. 1/4 of what it should be. Any ideas? :confused: Still starts and idles and revs in neutral, just not under load.
Thanks in advance for any and all information!!

Welcome to iboats. possible dirty carb, or coil gone bad. check your spark on both plugs. it will run on only one cylinder. post back results.

Sure sounds like it is running on one.

Most likely fault is loss of spark from one magneto. Coil, points, condenser.

Another possibility is a bad or broken reed.

Definitly running on one. Check plugs and spark.
