Yes , the mix is the same as a standard out board motor. Pre-mix your gas oil mixture at a 50-1 ratio.

SOURCE: What oil and how to you check it in a 93 kawsaki

Your 750 jet ski does not have a gear box. If you are referring to what looks like a filler cap on the front of the motor, that is the generator/flywheel cover and it is a dry compartment and should remain that way.

I have found that the jet ski will start prior to entering the water, but as soon as I launch the ski will not start...unless I remove the air filter case cover.? Any idea why this can happen?

Your stator sounds like it maybe not supplying enough ignition spark when the motor is under a load. When you put the ski in the water the motor is under much more of a load then when out of the water or on a trailer. Those are the signs of a stator going bad. Another option would be leaking crank seals. The seals need to hold pressure to pump the fuel to the motor. Sometimes the crank seals can burn up the stator if the seals are leaking. You can remove the flywheel cover and to inspect for a leaky front crank seal. It should be dry inside, but if it is all oily and wet, your seals are leaking.

Jet ski troubleshooting

kawasaki ultra 260's are only cooled by lake or sea water so if the water supply gets blocked then it will overheat ! did it definatly overheat or just loose power because the superchargers do sieze up due to damp air or the pully bearing , also the dipsticks on them sometimes shear off and lock the cogs ! does the engine still run up on a hose pipe ? also has the ski been left a long time not used without fogging the valves in the head ? this is my job so get back to me ( 30 yrs ) ..

sounds like you hydro locked it and possibly blew out a reed in your engine intake or worse, you may have bent a crank rod. But before you go tearing it apart make sure all the water is out of motor and theres none in the fuel tank then put in a new set of plugs and see what happens,

How to maintain my jet ski?

If you plan to store a jet ski in a garage, you will need to make sure it is dry and cool and with limited exposure to the sun. In general, you need to do what you can to prevent rust and other grime that eventually may cause mechanical issues.

Washing your jet ski is also needed after every use. You can use your car wash products. I also suggest to read the user's manual, it may include tips about maintaining your jet ski.

You can protect the engine with a special spray and water repellant.

If you plan to store your jet ski for a while, it is preferred that you will disconnect the battery.

Jet ski bogs out under load.

I had a similar experience with that model. It turned out to be a mouse nest in the water box. However , in this case i think you just have some moisture corrosion on the rubber tipped needle in the carburetor. Clean that part of the carb and do not alter the tiny spring in any way. If that does not work open the electronics box, if it is wet , dry it out , and seal it back up. Those are the three things I know of that will cause your problem. Start with the carb.

Jet ski's do not have an adjustment on the oil pumps unless they are cable operated. Most just run off the end of the crankshaft. If the machine sits for a while and the oil pump seal is leaking. Oil will collect in the crankcase and take a few minutes of running to clear out. You can live with this, replace the pump, or block off the pump and pre-mix. A popular, cheap solution but a pain when it comes to refueling. As for the lack of power you probably have water corrosion in your carburetor nothing a simple cleaning won't cure.

No Spark to a 1994-1995 Polaris SL Jet ski

first have you done what is necessary for that such as draining the oil (unless it's a two stroke) draining the gas and refiling it with fresh gas and a couple bottles of gas line antifreeze (it sucks up water) ... for the electrical parts ... spray them with wd40... that will force out any moisture at all and oil does not conduct electricity.
