I live in Houston and it really only get's below freezing about 15 nights a year w/ the absolute low being typically around 20. I have heard from others in this area that they have never drained their block and the boat is fine. I'm not ready to go that far but am considering using some block heaters instead on winterizing. Anyone ever done this? Opinions?
Here are a couple of the options:

haven't done this myself as I have the dealer do a full winterization on my boat, but I think there are a minimal number of plugs to pull to drain the water from your block. I bet someone will confirm that this can be done in 15 mins or so once you know what you're doing. For me, I'd go this route vs the heater or maybe even drain & the heater. It would give me more peace of mind.Drew

i think the block heater would work fine as long as there is not a like a major winter storm that knocks out electricity in your storage unit. likely hood of that is low and if that were to happen im sure you could head over there and drain it all real quickDavid

I wouldn't mess with that dipstick tube setup at all!
The magnet ones seem simple enough - but I'd consider adding a bungee cord or something to make sure it doesn't fall off. Not willing to bet the farm on it without some insurance.
If you're really serious about it, you could go with something like this-
Basically knock out one of the soft plugs on the end of the block and in this goes.
Soft plugs are the silver dollar looking plugs on the right and left. They are a press fit and not too terrible to get to.
At the time it seemed like a good idea...

I am using a heater that is strapped to the bottom of the oil pan. It doesn't get that cold down here anyways. Boat is in a shop and covered up and then the heater. Should be fine.Jack Beams

If you have a heater installed, those hoses and heat exchanger probably wouldn't benefit from the block heater.1998 Mobius

I read those reviews on Amazon. While people say is "keep the oil warm for start", I couldn't find anywhere that a temperature was referred to. What temp will it warm up to? How much does that radiate heat out? Seemed like a lot of people who bought something and assumed it worked.
For a little less money, I think I would opt for a light bulb in the bilge. I know how hot a light bulb can get and I know the insulated engine box will keep it warm while the light is on. That is what I use here in Tampa. Although, I doubt I needed it so far.1997 MasterCraft 205

Alight bulb is good but 2 in series will provide a back up if one burns out. A little old man taught me this trick for pump houses in the winter time09 21v LAUNCH
