Warm up the engine following the flushing instructions to bring the engine up to the right temperature. Remember, never run your Sea-Doo SWITCH pontoon without supplying water to the exhaust system and never run it longer than 2 minutes. When connecting your garden hose, be sure to use the proper connection found at the center of the hull.
Repeat the engine warm-up process twice, letting the drive shaft cool down for 5 minutes between each cycle.
Run the engine for 10 seconds at 4,000 RPM and shut it off at this RPM by pulling the tether cord. This will move oil from the PTO housing to the oil tank for maximum oil draining.
