I have a 225hp model J225vxsif with good even compression. My problem started at the end of last season I had issues with the engine just slowing down at wide open throttle. I changed plugs coils wires stator the power pack and trigger. Only thing I did not change was the rectifier. The last 3 times I have been out the engine ran great and this weekend it started the slowing down thing again. Shut the engine off a she would run about a mile and slow down again, on the way back ran fine. I just can not figure out what is going on. I cut the filter open and there is no water. Pulled the plugs and no signs of water. When it does do it I simply turn the engine off and start it right back up and it will run for a mile or so and slow down. But like I said after a couple time coming back it ran for about 6 miles ok. my compression numbers are 114 to 110 and the engine starts better then it ever have but now this problem has started again. I am trying to get thru this year and will re power in the fall. Also my temp runs right at 140 degrees and no alarms. Thanks in advance for you help.
