I was gonna say get a plug in cooler.
I removed the refrige from my 265 Express. Waste of space. Its in my shed next to the microwave.
Fishboxes & Livewells are insulated. Hold ice better than in Igloo.
What are you gonna keep cold? For how long? You gonna keep a 12 pack of beer? You'll drink it before it gets cold.
You gonna keep some ketchup and mayonaise and pickles?? make a tray of ice cubes?
Its sounds silly when you think about it.
And they cost $700
Realistically, refriges are for 30' + boats with an actual
cabin. I don't even consider my 265 as a cabin...its a big cuddy for taking a nap and storing fishing gear.
There is a couple at my marina with a 22 walkaround. They stay on it all weekend. Ice in a cooler lasts a weekend.
What you need is a freezer in your garage. Buy cheap ice at Costco. Take it back & forth to the boat in a cooler.
Sorry. I'm saying all this in a light-hearted tone...
