    Default Winterizing 345 Surf Motor

    Any quick info on the difference between winterizing the 345 and the 325/330 would be greatly appreciated. My new boat has been in the water, and it is supposed to get below freezing tonight. The indmar manual does not show anything for the 345 motor. I plan on pulling the hoses and plugs. I also plan on putting a shop light in the engine compartment for some heat. Thanks.

    It should not be a hard freeze, only reaching freezing temps for a few hours wont hurt, put a shop light in for piece of mind .
    should not be different than the 325 motor.

    It is no different just the two plugs on the bottom of the block two plugs at the v drive one on the exhaust and the three hoses on the water pump and the connected hose lines laying across the top of the transmission.

    Yes nothing different. Sounds like you got a good plan already.
