I'm so disappointed. Fixed every issue I could find. I leveled the arms on the carbs and it held pressure a little better, hardly leaked at all on the 10 psi test. Bypassed the fuel selector, got rid of the aftermarket fuel filter. It fired right up on the trailer, idled better than it ever had by far and away, and just sounded like a healthy seadoo should. No more erratic idle, I had the idle set at 3250 on the trailer and just sat there and purred and didn't hardly move at all. Rev it up and it would come right back down to the 3250. Thought it was 100 percent fixed. Killed the engine. Let it sit 10 minutes. Fired right back up with a touch of the button. Took it to the lake to dunk the ski in to make sure it would run right for the trip.....
Wouldn't start in the water. Pulled out of the water. Fired right up. Started it and then dunked it in the water, died within like 4 seconds of the pump getting in. It would only idle if I turned up the throttle to like 2500 rpms, tried all different settings on the low speed. None of them made a difference really. Here is what I don't understand. I hook it up to the hose. Runs perfect. So I don't think it is a water ingestion issue or leaking gasket, but honest to God, I think the engine is just tired and needs to be replaced/major work.
I thought it was figured out for a great fourth weekend, but it looks like we'll be taking only 2 skis and not my spx. I'll be forced to bring the old reliable Yammy.
Sigh.
