Using engine during the winter

[Alexis]

Hello,
Our sailing yacht has a 18hp VP2002 indirect cooling diesel engine driving a sail drive. As she's insulated and has a diesel heater, we will be sailing her through the winter.
Question: considering it will be used regularily (minimum once every fortnight) is there something I should do to prevent water freezing in the raw water circuit, including exhaust?
Our boat lives on fresh water on lake Geneva.

Thank you, Alexis

I think you'll find that the raw water will stay at the temperature of the lake, so unless that freezes, which as you're planning on using her I presume it doesn't, you shouldn't have a problem.

Lake Geneva frozen over

I'm sure I've seen the lake frozen in winter.....?

If you have shorepower, fit an electric heater near the raw water heat exchanger
