    2006 Kawasaki STX-12f COMPLETELY DEAD!

    So I picked up a STX-12F for my step son's first ski. It's a 2006 with 60 hours in pretty good shape. It was running last season, had all the hoses exchanged and full service done. Seller said it wouldn't start, it needed a battery.

    He installed a battery and we've got NOTHING... no lights, no display, no turn over, NOTHING.

    I checked the only fuse I found and pulled the orange magnetic key and it had power going in and out of it.

    I'm not even sure where to start on this.

    Any suggestions?

    Thanks,

    Mark

    Unplug all the electrical connectors in the harness and inspect them for moisture, corrosion, and burn marks. There is a harness that lays in the belly under the storage bin that gets wet. Check it and secure it higher in the hull so it stays dry.

    Steve,

    Thank you so much for your reply. I actually found the problem. The seller put a brand new battery in it and said he put it on the charger so I thought we had enough current. When I brought it to my shop, I did some testing and realized a few hours later the battery was only putting out 5V.

    I replaced the battery and it started right up.

    Unfortunately, it didn't make it out of the no wake zone, the over heat buzzer came on. I put it back on the trailer because no water was coming out of the pisser (I blew through the hose, it was clear, unplugged it on the other end and it wasn't coming out of the engine itself) and thought I would look at the intake to make sure some mud dobbers hadn't built a nest. I hadn't done anything yet but found this... weird.

    Okay, I need help.... There's no water coming out of the brass nipple coming out of the exhaust. I've taken the ride plate off looking for blockage in the lines, I'm not sure where to check next. Any suggestions??

    Thanks!

    I have no idea what that hose is coming out of the ride plate.

    Sounds like the cooling passages in the exhaust are plugged up. Was this a saltwater 'Ski? Probably not flushed proper after each use.

    That “hose” is a bolt. I couldn’t begin to tell you how it got in there, why it was hanging down… it was the weirdest thing. I went to remove it and it just twisted off. It looks like the other spot right next to it had a broken bolt in it also.

    just an update, I was confused why water would come out the pisser when hooked to a hose but would overheat when the ski was placed in the water. It turns out the pressure from the hose makes it flow but the impeller in the pump was crap.

    thanks for your help.

    That bolt is left over from the crate the ski was shipped in, the dealer should of removed it. My son's STX 15F had them left in too, gave the dealer an ear full about that...

    It is impressive that it held in there for this long... probably a record.
