I totally agree. I think there has to be a physical issue with the ski of some kind, but I can't figure out what it is. It was running up to 74 mph when it was low on fuel, but I only weight 135 lbs. so I don't really think weight is an issue.
Compression was 130-135 last I checked. These pics are before I changed the impeller. I have put some RTV in any cavities and edges around the intake grate and ride plate for good measure, but it didn't make any difference.
