Winterization or run it on the muffs once a month?

I run mine all year but do what others have suggested and leave the enignes down in the winter to allow the water to drain out.

The inborad on the yacht gets antifreeze run through to prevent the water jacket freezing and splitting the block.

10 or 15 minutes at idle should be long enough to get an outboard up to temp. I would guess that anything more than a couple or three would do the trick.

My best days at sea have been in February and March. As others have said: get some warm clothes and use it year round.
