Step by step winterization on my 2006 Mastercraft X15 with the Indmar MCX 350 inboard engine. This video will show you how to fill the engine with antifreeze without warming up the motor or removing the thermostat. This is applicable to many inboard/outbard, ski, and wakeboard boats. I will also go through winterizing your ballast system and heater.
