It depends upon where the vessel is and, most importantly, whether on land or in the water. It also depends upon what you intend to do with her over the next four to six weeks.

If she is up there in Renfrewshire on the land, what's the hurry? If she's in the water or about to be put in and you intend to use her - no problem. If the Clyde doen't freeze, nor will your engine!

Why take the anti freeze out anyway? It is an anti corrosive so there is a benefit in leaving it in alla time. When my new engine was installed it was filled with standard mix of 33% anti freeze & that was what is recommended for year round use according to the manual (It actually gives 33-50% anti-freeze, but in southern UK, I doubt that we will experience minus 20 deg C, so I stick with 33%)

By leaving the antifreeze in I assumeyou mean the sea water side? If you mean the fresh water cooled side, then leave it in for 2/3 years and then change it. After all the antifreeze mixture/coolant in your car engine is only changed every 2/3 years so it should be the same for your marine engine. Obviousle replace the seawater impellor and alternator belt if you have removed them.
