I bought the ski a couple months ago with 71 hours on it. The first problem I had was the engine would start bogging above 5k RPM but not consitantly. I could slow down four or five times then it would take off again like it hadn't happened. I checked the ground connection and retightened them and it seemed to go away. Then the oil pump cap came loose and leaked all the oil out. I was oh shore when the warning light came on so no damage was caused. I fix that and run the water hose to it, no leak and ski runs fine. Take it back to the lake and within a minute it starts missing on idle, I get to open water and it takes off running smooth for about 200 yards and starts booging in all RPM's. My meter read "MAINT" and would only idle.
What do I look at first?
Thank you for your time. Jason
