Inboards and cold weather?

[bsb]

Thanks for the info. I plan on using the boat most of the winter. I trailer the boat and really did not want to have to winterize it every time i took the boat out. Sometimes 3-4 times a week. I have seen engine compartment heaters and thought maybe that might be an option. Usually doesn't get that cold here in southern virginia but sometimes it does. I guess if there is no option i will flush with antifreeze everytime. WHAT A PAIN!!!!!!
