Problem with Yamaha 40-HS 2 stroke electric start – 1991?
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.
