Ok guys, I'v done tons of searching and followed some good advice from previous posts but still have water intake issues. I have two issues,
1) when I sub, fail BR's (every time), or ski lays on its side for any amount of time I get water in the carbs and it of course runs like crap for a while till I run it through. I have a new factory hood seal, good latch, hood straps, glassed front and upper intake, opened both rear intakes, added "bridges" to smooth out the sides of the hood where it meets the hull and added a layer of foam strip to the bottom of the hood. Also have outer wears on my prok filters. I tried a stock air box but couldnt get it to run good enough. I even made a splash shield out of plastic tupperwear dish and mounted it between the carbs and the filters.

2) when doing a tail stand, I.E. after a 180 or sub the motor runs out of air super fast since it only gets air from the back of the hood. Im thinking about getting some of those frogzskin vents for the front of the hood. Maybe mount one 2" I.D. on either side of the front like where I glassed it shut.

did my first water canon on saturday...shortly after, when i got back in the tray, my bilge came on, and ran for over a minute pumping water out, and my ski took on a little water in the carbs (was bogging and wouldnt get on plane). i immediately rode back to shore for fear that i was sinking (thought maybe a hose off the head came off and was filling the ski with water...happened last time i was out)...got back to shore, and all the water was pumped out by then...must have just been water coming in the front air intakes (i don't have the 3" hoses running from the hood to the bottom of the ski)

I did all of this to my 750sx as well and exactly the same things happened to me! Fortunely I recently switched over to the sj platform but the hood was modded as follows: http://personal.jax.bellsouth.net/s/o/soul_man/Super_Jet_Hood_Modifications.html and it does not experience any of the problems the kaw had. Perhaps modding the hood like this could be your solution.
