Why Put a Plastic Bag Over the Lower Unit of an Outboard Motor for Winterizing?
To keep Bugs and/or rodents out. Mud wasps could build a nest in there and
clog it up.
This makes senses now. I doubt this matters now that the outdoor is
cold and no flying insects any more. But I will do this next spring to
prevent wraps from building nest inside the water passageway.
Thanks.
