96 GSX Bogs @ 4000 rpms

[I Drink Alone]

My carb filters clogged up about every year and a half, so based on advise from this forum I took them out and put in a replaceable in-line filter just before the MAG carb and replaced all the fuel lines. Doo ran great 1st couple times out, probably 3 or 4 hours. Then it started great but began bogging down on accel. Starts good, idles good, runs up to about 4000rpm if I throttle slowly and gets on plane, but more throttle than that and it actually slows down. It did this for about 7 or 8 mins. then was okay. Ran for 30-40 mins. wide open, donuts, the works, and then began bogging again. Cold, warm, choked, unchoked, no matter it does the same now and won't come out of it.

Rechecked all hose clamps, rechecked RAVE diaphragms. Everything fine but seems to be about when the RAVE's should be opening and it gets a dramatic loss of power; never dies just sounds like it wants to and will run all day at 4000. Plugs were new when I did the other work and are now slightly dark but clean. Compression about 140. Would anything electronic do this or do I need to tear the carbs down further?

Welcome to the forum I Drink Alone...and yes seadoo's might just make you do that...I would check the internal filters in the carbs for more crap that might cause that. It sounds like you need to remove the carburetors and clean them. If you're careful and don't tear or damage the diaphragms you won't need to buy a rebuild kit. If you do need a re-build the seadoo forum has a "Parts" site now that can help with all your parts needs. Click on the link at the top of the page or on the home page for a link.
Keep us posted on your progress.

I eliminated the filters in the carbs. Replaced all with fuel injection hose and filter in-line 6" before pump.

I wouldn't leave the small filters out as that is the last filter of defense to keep all the very tiny particles from entering the carburetors. The screens in the filters are very fine, where as the in line filter won't be as fine or it would block fuel flow. You need to replace the filters. If you don't the next time they get clogged you won't be able to clean the passages in the carburetors.
