Why Put a Plastic Bag Over the Lower Unit of an Outboard Motor for Winterizing?
I am wondering why people want to put a plastic bag over the lower unit
of an outboard motor for winterizing (with holes on the bottom of the plastic bag for drainage). I come across this suggestions in this newsgroup; but I don't understand the reasoning. I understand that rain water or melted snow water may find its way into the lower unit. But I think they will be naturally drained out from the lower unit, right? Why do I need to cover the lower unit if the water will be gone by itself anyway? The owner manual of my Mercury outboard motor doesn't say anything about covering up the lower unit in freezing cold winter either. Any idea? Thanks. Jay Chan |

To keep Bugs and/or rodents out. Mud wasps could build a nest in there and
clog it up. Paul wrote in message oups.com...

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. Jay Chan |
