whats up guys. what i have here is a 2003 stx-r 1200 that is taking on water... never had the problem before motor is strong and runs fine but the first time i went out this season i noticed it was taking on water. first time out i hooked up to my anchor n noticed ski sinking slowly. the plugs were in n i have no holes in the hull at all..it took on almost enough water to cover the battery does anyone on here have any idea what it could be? gaskets? seals? thank you in advance

 

Not much activity on this forum this year.
Did you ever solve this problem?
My skis are older than yours, but in general....
Leaks are either bad coolling hoses or connections, bad driveshaft bearing seals or mount, or bad thru-hull fittings or cables (trim / reverse cables). You already ruled out drain plug or hull damage, and you don't even want to think about a cracked block.

If its leaking that bad, just stand in shallow water and look inside. Or haul it out on the trailer with water inside (careful... too much water can overload the trailer design) and look to see where it drains OUT.
