1996 gtx cavitation

[Technical Support]

If you are reving and not going, you just don't know what to look for - either take the ski to a dealer, or take the pump off and send it to www.impros.com for repair. There is a tech artice here about inspecting the pump.

The problem is the plastic ride shoe is not sealed to the hull. Remove the ride plate and grate. Grab the ride shoe (under the scoop grate) and pull it out. I'll bet it almost falls out. It should be glued to the hull with silicone and be very difficult to remove, but it won't be. It will suck air through the pump and not water.

I just aquired a '96 gtx. It seems to run fine on the trailer, but when it is in the water, it feels like its not getting any water through the pump. When I hit the throttle the rpms rev high and the ski hardly moves. I removed the pump and driveshaft to inspect the impeller and driveshaft, everything looks fine. What is wrong with this thing?

I had the same type of problem, traced it to a missing hose clamp that fastens the protection hose to the carbon ring, it was sucking air straight through. Replaced the clamp and no problems since - with cavitation at least!

Bill,
Would that also cause the boat to take on water when it is just sitting in the water? I forgot to memtion that the hull had more water than normal when I left in in the water overnight, the boat was listing to the side. Is the ride shoe located where the driveshaft enters the hull?

On some models of Sea Doo's, like yours, the black plastic ride shoe is a seperate piece from the pump support plate. On other models, it is a one piece pump support/ride shoe.

The ride shoe is located directly behind the scoop grate and diverts the water from the lake into the pump.

It has nothing to do with your water leak.

Water typically comes in through the driveshaft seal when parked in the water overnight. BTW, leaving any watercraft parked in the water overnite is sooner or later going to end up ugly, and expensive. At least beach it overnite.

Alright, just came in from the garage. You were right the shoe came out like it was not even glued in there. My question now is what product do i need to keep it securely in place?

Thanks for the help!!

Marine RTV silicone, "The Right Stuff", Ultra black, Ultra Blue........ Any good quality silicone.

Use a massive amount, wipe up the excess.

BTW, I knew I was right before you took it apart [img]smile.gif[/img]

Bill,
Why do you say it is not good to leave your seadoo in the water overnight? I have a camper at the lake and about 10 times a year I leave my seadoo's in the water for about 2 days. Just curious... Thanks

Because sooner or later, you will regret it.

Driveshafts have seals to keep the water out. Eventually the seals will need to be replaced. When they start leaking, will you know it? If not, overnite is plenty of time for a Sea Doo to fill with water, even with the smallest leak.

Beach it or trailer it, and don't ruin your vacation time repairing it.......
