    SC Gear Failure, Great 4th Weekend

    So it was not the best of holiday weekends for me. I had just passed the no wake zone at the lake and went to give it some throttle and it felt sluggish as all hell. I immediately let off and while idling to the dock (not even 20 yards from the no wake) my SC completely stopped spooling. I knew my SC was gone but I then continued to pull it out of the ski......







    Also, not that it makes much of a difference, there are only 5 of 7 ceramic bearings left. So 2 of them took a ride through my motor.

    So now my questions begin:


    1. What tools will I need to fix this the right way?
    2. What are the necessary steps/precautions I need to be aware of?
    3. How much will this cost me to fix?

    How many hours on your motor?
    You got to pull out the motor, remove the front pump assy and PTO housing and inspect the damage.

    Not good! This is the first time I've seen an 06-07 gear break. Seen plenty of 04-05 gears break though as they are thinner.

    The engine needs to come out and the PTO housing removed.
    More than likely you will find damage to the timing chain. I would replace it regardless.
    You will have 40 needle bearings that used to be between the gear and the shaft scattered in your engine. Most will be found in the front oil scavenger pump screen.
    How much will it cost depends on the damage you find inside. Front oil pump assembly is bound to be shot. Inspect rear pump carefully once you get the PTO housing off.

    Ouch, sorry about your misfortune. I feel your pain, I've had my share of S/C blowups... So this S/C had Riva metal washers, and Riva ceramic bearings?

    There is almost 90 hrs on the motor but Jerry rebuilt it with riva washers and bearings at 40 something hrs. I will already be replacing the oil pump no matter what but what about the gear in the motor? This gear failure will be like a weekend in Vegas compared to what would happen if that gear trashes my bottom end.

    Your bottom end should be fine. Most of the debris will be found in the PTO housing and front oil pump screen. Be sure to replace the timing chain too!

    Sorry about that. 22,000 members and only one of me so it's impossible to keep up with anymore.
