So the entire power band is fine, before 4k, and after 4k, but throttling past 4k, you get a hickup, like fuel or spark is being cut, throttle past it, and it sorts out and everything is fine and dandy. Any ideas?

Plugs and fuel filter are new. Both OEM.
Also, my boat used to go to just under 6k RPM (240 EFI mercury on 2003 challenger 2000), since we removed and replaced motor (to fix the fiberglass leaks on sea doo's crappy hull design), I top out at 5k rpm, and top speed went from 53 or so to 46.

Throttle cable not adjusted correctly to open throttle completely?

Anyone else experienced this? My 2003 Challenger 2000, purchased new in 2003, started showing some stress cracks around powerhead last summer. Water intrusion commenced. We completely removed powerhead and pump, and reinforced glass underneath and on top. We then changed grommet that is instaled between pump and powerhead, as well as all gaskets, and reinstalled the whole assembly (at great expense and time mind you). Well three days of use later, a huge stress crack emerges a little further past where we repaired, and water is spewing in pretty heavy now (bilge pump comes on every 3-4 minutes).

Hull repair was covered under warranty, but repair shop pretty much said that the whole thickness/quality of the sea doo hull is crap and they don't believe it can be fixed without completely rebuilding the back of the boat/hull.

Anyone else experienced this? We never hit the boat, or grounded it by the way. It is run on Nantucket sound in Cape cod, so there are frequently 4 footers, it isn't a lake. Any other ocean users see this aroundyear 3-5 of ownership? Any suggestions?

In the meantime, I am installing a secondary bilge pump to keep up with the leak until a permanent fix can be determined by BRP and the repair shop.
