Warm weather storage

I live in California.. so I dont worry about the temp going below freezing. I normally change the oil, tranny, then fog the cylinders and put stabil in the gas tank full.    Is there any advantage or disadvantage for draining the block of water? I was think that if I drained the block, the cooling system would be exposed to the air and could cause corrission. If the water stayed in, oxyegen could not get to the cooling system.

anyone?

Thanks much!    Time for the Nautiquie to go night night for the winter months.

Antifreeze will help control corrosion while the boat sits during off the season. Plain water will cause rust in the engine. If you don't believe it, just let it sit for about a month and then hook up a fake-a-lake and run it until the thermostat opens up and you'll see plenty of rusty water, that is if you have a cast iron block and intake.
