What to do when impeller is stuck on jet ski
To replace the impeller shaft on a 1992 jet ski, start by removing the jet pump assembly by unscrewing the bolts securing it to the hull. Once the pump is removed, detach the impeller by unscrewing the nut and pulling it off the shaft. Next, remove the old impeller shaft from the housing, ensuring you also replace any seals or bearings as needed. Finally, install the new impeller shaft, reassemble the impeller and jet pump, and secure everything back in place.
Yes, a Jet Ski can safely be beached as the impeller is hidden. However, it is recommended that you kill the engine before actually reaching land. And beaching the Jet Ski is hard on it's under surface - that takes a toll over time.
fix it
It sounds as if you may have an impeller or driveshaft issue. If the impeller, or the impeller housing is badly worn, the craft will loose power due to excessive tolerance between the two parts. This is very common when used in sandy bottom, shallow water conditions, as the sand picked up by the rotating impeller wears away at both the impeller, and the housing. Also, in the case of little, or no service maintenance, the driveshaft splines may be severely worn, due to no grease, at the coupler or the impeller end, causing slippage.
Did you fix your ski, it may be a bad seal and it is losing too much compression.
Only if you can fix it
ski jets dont exist
There are a lot of reasons. If the drain plugs aren't in, that would do it. Also, the impeller shaft seals or carbon ring may be worn. One way to tell is to get the jet ski dry, place it in the water, and then run it with the seat off. You should be able to tell where the water is coming from.
A jet ski for your ignition switch?
A jet ski-powered jet pack works by using water propulsion from a jet ski to lift the rider into the air. The main features of a jet ski-powered jet pack include a harness for the rider, a hose connecting the jet pack to the jet ski, and controls for steering and height adjustment.
Kawasaki, I think the first jet ski was made in 1974 I believe it was a 440cc stand up. You can find the definite answer at Kawasaki jet ski museum online.
