Why did my Jetski Sink

[DaveH63]

I had my jetski out for a good run.
I submarined it once and then road some more and fired up the bige pumps to empty out the hull.
I tied it to the dock. Weather was nice, no big waves.

An hour later it was sunk. the nose was on the lake bottom in about 3 feet of water. The tail was sticking up like a dabbling ducks but.

Why would it sink?

The seals where you drive shaft go out of your hull may be damaged or where you steering cable go though. Drain the hull and back the ski in with your trailer and look around them areas and see If that's where the water is coming through. Hope that helps you

Your gonna need to give us more details...like what kind of ski.

when I hear sub I think standups so if its a standup and has a scupper installed it could leak and sink your ski

If the bilge outlet is below the waterline it will sink your ski after you run the bilge - this primes a siphon from the outlet to the water intake of your pump.
