    Anyone Who Has A S/c Sea Doo

    S/c Sea Doos Are Not Designed To Be Jumped.
    Te S/c Spins At About 40,000rpm While In Air, And Drops Instanlty To About 12,000rpm When It Hits The Water. The Instant Stress Put On The S/c Ceramic Washers Often Times Shatters Them. If Your Boat Loses Top Speed And Rpm. Removed The Fresh Air Intake Hose Into S/c And Try And Spin The Impeller. If It Free Spins, The Ceramics Washers Have Been Sucked Inside The Engine. At This Point, Lots Of Damage Has Occured. About $2,800.00 Worth. The Engine Must Be Torn Down To The Crankshaft. I Have Rebuilt Many 4-tecs. At Least 20. I Have Never Had One In Which I Did Not Replace:
    Mag/pto Cover
    Oil Seperator
    Both Oil Pumps With Covers.
    I Replace The Oil Cooler
    And Most Often Times The Plain Bearings
    Occasionally A Crankshaft
    Now, In Most Cases, Bombardier Covers All This Damage And The Rebuild. It Is Free For The Customer. It Is Usually Covered Under An Emissions Warranty Up To 250 Hours or 4 years from purchase date, which ever comes first. Bring Your Boat To A Good Certified Sea Doo Dealer. If There Not Going To Do A Tear Down, There Not Good.
    **********************************
    Also, Do Not Use Synthetic Oil In S/c Engines. This Was A Service Bulletin From Sea Doo. It Doesnt Give The S/c Clutch Enough Friction And Fries It.

    I Dont Recommend After Market Intakes On S/c Engines.
    It Can Put An Excessive Load On S/c Clutch During Deceleteration Causing Ceramics Washers To Fall Apart.

    This info is about 1.5 years old....
    Yes, if the dealer is not willing to open the engine for a complete repair....RUN AWAY and find one that will. Never reinstall Ceramic S/C clutches. Buy steels from G/H.....................

    He mentions a good theory I have nto heard before about the RPMs the SC is spinning at when you jump and then when you hit the water. I wonder if this causes soem other time of damage over time.

    It's perfectly fine after you get the ceramic washers replaced with Jerry's washers or the new Riva metal washers. Bullet proof it even more with the addition of the '06 spec heavy duty clutch and ceramic bearings.
