Winter - inboard engine exterior protection

[seaboy]

Noticed this weekend after a run last week, that my inboard 5.0 Mercruiser engine was damp on various surfaces. The engine bay has Fire ports and is vented.

Some weather forecasters are saying we are in for a bad winter. I shall be leaving her in fresh water for the winter and I cannot do the usual Antifreeze winterising, but only fogging as the stern drive with the engine water intake is under a washboard fixed to the stern and cannot be fully tilted out of the water.

So to help with protection, I thought of using an old duvet wrapped around the engine.

What could I use to help prevent corrosion of various exterior surfaces.

Use of such as WD40 or what would you suggest.

thanks

I sling an old thick dressing gown over the engine, keeps the damp at bay.
I dont spray it with anything.

As ventilation is good to have I would never wrap anything over an engine. Spray liberally with WD40, ideally before it gets damp. I have been spraying my engines with WD40 for over 30 years and it does a good job at preventing corrosion.

in the past I have used ACF50 succesfully,
its used mostly for bike motors
lasts much longer than WD40

+1 for ACF 50

Also, if you have a pontoon mooring with electric then a tube heater will help keep the damp off and prevent freezing. If you are away from electricity though, in your shoes, I would be looking at fitting a closed cooling system to the engine to remove the frost and internal corrosion risk.
