Any boat shop will have a bilge fitting or go to Blowsion.com and get a pimp one.
Just get a flat drill bit to fire the hole in your ski...takes 15 seconds.
Then, just a piece of hose.
Bungee it down where your tool kit was, hook it to your battery and your ready to go and your ski is now much safer from sinking or water injestion.
Another good free mod to keep water out..... block off your front round air intake on your hood (you can use duct tape or a piece of plastic), cut a second matching intake in the back, and you have now stopped 3/4 of the water that comes into your ski. (search sxr hood mods on here! for pics)))
I've been riding an SXR for 7 years and these are great cheap mods!
