Looks like some cold low's coming in the next week or so. For those of us who have dumped our boats in already, what is everyone's opinion on the best way to keep the motors warm is we don't live close? Light bulb? Blanket?

Trying to not have to totally winterize the boat again. I have a Volvo 5.0FL I/O. I guess I could drain the manifold and block so that's fairly easy.

Any ideas?

Thank you!
