'89 JS550 Water dripping out around left sponson

[Dustinwild]

I have an '89 JS550, and I just had it out for the first ride of the year, and I noticed water dripping out of the bottom left corner of the hull, right at the seem between the little rear piece, and the rest of the hull. I can see a little hair line crack there when I wipe the water away, then it just keeps dripping, really slowly. Also, had a bunch of water come out of the left rear sponson while I was working on the ski.. Could have been just from banging around, but wonder if it's connected? Anyone know what I should do with this? I'm tempted to drill a tiny hole right at the seem, and let all the water out, then fill it back in, but I don't know if that's where the water inside it is coming from. Any tips would be great!

Common , hull extension leaking , not inside hull , drill a drain hole , drain , put in a skrew to plug hole , drain after riding , some 750s have water in hull too , on race skis , so we drilled a hole bottom back chime and drained it out , put skrew back in when done , kept on riding

The hull extensions and the sponsons, are not leaks into the hull.

For that mater, you could just remove the sponsons. Push the rivets
into the hull and seal the hull with some marine epoxy.

They might add a little stability for beginners, but after that, they
are reducing top speed.
