Bigger bulb. Use a new bulb. Don't ventilate. Make sure the bulb is a
reasonable distance from anything combustable. A small oil filled space
heater would be a lot better.

It's going to be below freezing tonight in an area where winterizing is
optional. I chose not to winterize so that I could use my boat on the
nice days during the winter.

My friend told me to put a 40 watt utility light in the engine compartment
for cold nights. So, I leave a 40 watt bulb burning in the engine
compartment of my Sea Ray 185. What do you think of this winterizing
solution?
