In my search up here in the northern states for a Regal cruiser I've =
come across several parties that have their vessel in heated storage. =
They claim that they do not winterize their boat.

Put aside the obvious risk of "What if you loose power and heat" ... =
what about the engine? I thought it was not good to leave it sit for =
5-6 months with raw water in the block, as rust corrosion would be =
accelerated. I thought that was one of the side benefits of cooling =
system flush with winterizing fluid as it protected against corrosion.

Also ... I thought you were not supposed to leave the engine sit without =
fogging to protect internal surfaces.

Can anyone shed some light on this topic from practical, mechanical =
experience?

Thanks,

Bob
