Hello,I have a 2012 115 opti that has a jet pump on it. It started to cut out while at 5k rpm which is wot for the pump. The motor would surge and cut. Then it got to the point where I would have to idle for a bit and then go again. It would run good for about 45 seconds and then start to cut and surge again. When it cuts out the motor would only run to 4K and hold there at wot. After a few attempts the motor will now only run to 4K. I could not get it to go any more. Any thoughts on this? There might be 150 hrs on this motor. I don't use it that often. It was bought new by me and has always run perfect. On a side note the air temp was 20 dgrees and the water temp was 36. I did have a steady stream of water and water pressure on the gauge.
