    10w 40 non synthetic is recommended by the manufacturer, synthetic is specifically not recommended.

    If it is the motorcycle oil you should be fine. Main thing is you do not want a oil that has friction modifiers in the oil due to the clutch slipping. You can use the AMSOIL 10w-40 Synthetic Marine Oil. It is safe. http://www.amsoil.com/redirect.cgi?z...storefront/wcf

    Here is the test on the Sea-Doo oil and the AMSOIL for the clutches.

    I use this stuff and it works great 102 hrs. and still running strong the only thing I dont like is you have to order it but its well worth it IMO.
