I have a '05 Honda Aquatrax Turbo that I'm having trouble with. The engine starts and idles good but power is intermittant. If your stopped and nail the throttle it will come out of the hole and run perfect one time, then if you slow down and do it again it will only reach about half speed. When it runs slow the engine feels just slightly rough but the power is just not there. If you stay on it it will somtimes just come alive as if you flipped a switch and run good again. The ski has about 20hrs on it and impeller looks good. Any advice???

never heard of that before. check pwctoday.com or greenhulk.net. there is a ton of good information on those two sites.

Sounds like you're getting heat soak to your ICU. Are you getting any warnings?

+1 on PWCtoday or greenhulk

That's what it sounds like to me, possible fuel delivery issue via the PCM? Also, does it always have a good hole shot when you first start compared to if it's been running a while and is hot?

I bought my 07 f-12 new,  after the first summer the I had the same prob,    It turned out to only be the spark plugs.  
Hope it was the same for you.  Easy fix

Ditto on checking spark plugs.
