I recently had my Yamaha 40-HS boat motor rebuilt. I had it out in the water for about 20 minutes. It was running great then it became sporadic and began sputtering and misfiring with loss of power. I took it back to the mechanic who identified the problem as a stator (broke piece.) He then replaced the stator. I am now having the same problem after 20 minutes in the water. Please advise.

I had the same problem with a 40 horse Mariner.....would run great until warmed up. It is in the ignition. The stator is definitely what he should start with because that it what fires up the motor. In a car, this would be the ignition coil. Take it back to him, there is probably something wrong with the stator he put in.......has to be it.

All could fire even at idle. If its in basic terms firing on one at idle then you definately've a topic with 2 carbs on the idle ingredient. get rid of all carb's, strip, sparkling and replace. Use carb and choke cleanser yet be carefull it incredibly is going to sting your eyes, placed on protecting glasses.
