newbee help....

I have a 96 gsx, ran fine one day, the next it feels like running on 1 cyl. but both are fireing & plugs are new. runs great out of water but under load in the water it revs rite up for 2 seconds, then dies down to 4000 rpm's and will chug along and wont rev. almost like a clogged filter but it runs perfect in the yard hooked to a hose ! Any ideas would be appreciated, Thanks

A rotax engine should have good health at 150 psi compression and MOST importantly, a clean fuel delivery. 99% of Seadoo problems are fuel system related.
