SeaDoo Repair

Lake Ozark SeaDoo Winterization

Contact us to perform expert winterization for any SeaDoo.

  • Start the SeaDoo spraying fog oil into the intake until exhaust becomes smoky, less than 30-seconds. We do not over heat the motor, but the more fog oil the better.
  • Pull the spark plugs out, spray fog oil into each cylinder for 15 seconds, then turn the SeaDoo motor for half a second to move the pistons up and down. Put the spark plugs in.
  • With freezing winter weather ahead, we flush all water out of the cooling system and ad some anti freeze back to the system. If water freezes in the SeaDoo motor, it can crack the block and cylinders.
  • Pull the battery and charge at 2-amps or below once a month until taking the SeaDoo out for it first run of the year.
  • Add a cap of fuel stabilizer in the gas tank, ¼ of what the bottle tells you to use.
