Change the oil in the jet pump cones. Tha's the oil they are talking about. You can use full synthic 75w90 gear oil or seadoo jet pump oil if you want to pay more .Change the oil injection filters and small lines for the oil pumps every few years. Make sure you put the same oil in the boat as the previous owner or your you need to drain and fill it up backup. Mixing different oils is bad. Make sure you use seadoo approved full synthic oil. You should have hose adapters that your hook to each enigne to run them at idel out of the water. Change the spark plugs after you run it for a little bit after storage. Check your bilge and blower to make sure they work since you need both to operate it properly.

It is pretty much all the same stuff as seadoo jetski's except for the blower and bilge pump sometimes.

The buzers go out on these boats 2. Does the boat start?

Test starter and compression test engine. Engine should move very freely with the plugs out.

All the new Seadoo jet pumps are all plastic you can only get a brass/plastic pump used. The white wear ring is a cheap aftermarket mark one that ususally doen't fit that well thats why it pulls out so easy.The OEM wear rings are best. All OEM wear rings are fiberglass with plastic over them. When you do the wear rings and impller fixes and you still have cavitation look at replacing the boot and carbone ring. The one engine that with all the cavitation sounds like the carbone ring assembly.

Usually fuel or oil. If you have an oil injection system I check out all the lines and check carb\fuel system or something broke off in the cylinder. That looks like a fuel issue.
