Issue with 1999 GTX Limited - won't accelerate pasted 30mph/3500rpm in water

[RG0389]

Just purchased a 10999 GTX LTD. compression 130 both cylinders . Replaced fuel lines, rebuilt carbs. Starts fine, runs well at idle. Accelerates well off idle. Wont accelerate past 30 MPH/3500 RPM in the water. Runs like a top till then. I've read alot of posts and haven't seen one that describes this specific issue. Any help would be appreciated.

You are describing 80 % of the posts on here....usually its a fuel delivery problem. Start with the battery fully charged, load test it. Check your charging circuit,,.check compression,,,run the inline fuel line directly from the fuel pickup to the carb.

What're the plugs like?

They were wet, but I haven't had the weather to do a full throttle cutoff.

My 96 GTX acted like this when the voltage regulator was bad. Not sure if the 99 is the same. There is a wire you can disconnect near the regulator that then lets the ski run on the battery only as a diagnostic. If it runs great, there you go. That has helped me find several failed regulators (I had a run of bad luck). Make sure that the battery is good and fully charged because that’s providing all the electrical power.
