Since we do not get too many cold days in Houston and I want to boat all Winter I was considering an engine compartment heater as opposed to winterizing, Pros, Cons????

I don't know you weather in detail, normally most people will say it takes into the mid 20's to crack the block. Keep in mind this can cost $5k-$10k to fix so a mistake is costly.

Some people put light bulb in, subject to burn out. There are magnetic block heaters. Real boat heaters that are thermostat controlled.

You always have to worry if someone trips over your extention cord to the boat.

You never know when you are on business trip and mid 30's all of a sudden is severe cold.

Pulling a few plugs and hoses will drain the engine adequately. I think still the safe thing to do.

There's more freeze damage done to boats every year in Texas than in Minnesota.

I'm sure these boat heaters have been around and have a good safety record, but I'd be a nervous having a 750 watt heater running in my boat all winter, not to mention that a lot of those massive winter power outages are caused by ice storms.

Seriously, the block can be drained to MasterCraft's recommendations in about 10 minutes with only a screw driver and a socket wrench - both block plugs, unscrew the exhaust manifold drain (by hand), release the tranny cooler hose clamp and pull the hose off, detach the heater core return line and blow into it.
