I suggest you wipe the engine very clean and see where the oil is coming from. If it happens only when It's running, be sure the oil is full before you start it. Don't let it run for more than a couple minutes on the hose ad that seadoo has interloping cooling and it will over heat the Jet Pump seals and bearings If it runs long. If you have to after you clean it up place paper towels in the bottom so you can see where it is coming from. It could be a hose fitting or a crack. Look real close.
