    Default Draining heater hose on an 8.1

    I've gone through the boat and drained everything but am not sure where the heater hose is. Does anyone have a picture or diagram so I can verify that I have that emptied. Thanks

    Can you find your heater unit/circulating pump - usually on the passenger side ? It should have 2 lines to the motor. Blow some air (not high pressure) into there to remove excess water. Pretty sure on the unit there is an upper and lower hose - you can pour antifreeze in there with a funnel.
