oil in bottom of ice box -sea frost system

I am close to making an offer on a sabre I have been looking at. It has a Sea Frost engine run refrigeration, water cooled.

I noticed that there was a pool of reddish tan oil near the ice box drain; under the cold plate.

I am unfamiliar with this system. Is it possible this oil leaked from the sea frost?

if so what caused this, etc?

There's a chance it's compressor oil from a freon leak...

Antifreeze from being winterized?

Re: oil in bottom of ice box -sea frost system

The red oily liquid is antifreeze. Seafrost uses it as the eutectic in the cold plates. As they age, the nylon fittings around the copper refrigerant lines can loosen, allowing the eutectic to leak out. Carefully tighten the fittings and the leak should stop. You will then need to refill the cold plate with a mixture of water and antifreeze. There is a fill plug in the top of the plate, but if you do not have access to the fill plug, you can drill and tap a hole in the corner of the plate as a new fill spot. I no longer have the specs, but contact Cleve at Seafrost and he will gladly walk you through the process.
