I have a water leak coming inside the ski. I have a 1997 GTX. Not sure what the area is called so I included a pic with a arrow going to the spot the water is coming in at. Appreciate any help.
Are you asking for advice how to fix it? Take it off and put a little 515 on the threads then screw it back on. Brass fitting to the muffler can be fairly tight, but don't over torque the water valve that goes on top that. Recheck and see if it still leaks, if it does remove again and readdress.
Note: If you don't have loctite 515 laying around, you could wrap the brass fitting threads in teflon tape then reassemble, that should work equally well.
If it's just the plastic that threads on the muffler you can typically turn them 1 full turn without even removing them and stop the leak at the threads.
