Add a Heat Exchanger to a Standard Refrigerator

I have a midsized non frost free GE fridge on the boat.
I was thinking what if you looped some 1/4 inch copper tubing and followed the existing condenser steel loops and wire tied the copper tube to the steel tubes of the condenser.
Do it so the copper tube touches the steel tube of the condenser.
Then ran a small bait well type pump using a relay tied to the compressor on off thermostat. the seawater would cool the condenser better yes or no?

The cabin heats up in the summer and I dont like the fridge adding to the heat load in the cabin. Compressor motor also gets quite warm.
Is it worth trying? Or am I crazy to bother.

Re: add a heat exchanger to a standard fridgerator

When anyone asks "Am I crazy?" the answer is yes. However that sounds like a neat idea. It does sound like a lot of work. Before you go to all the trouble of a permanent installation, do a temporary set up and measure the water temp going in and out to see if it picked up any heat. I think good contact with the condenser tubes will be key to how well this works.
