Additional notes about Copper vs Copper Nickel. Standard copper which a lot of coolers are made of is good for marine environments but is only partially resistant to the elements of salt water. The effects of a failed heat exchanger vary from simple engine running warm, leaking externally, loss of antifreeze coolant. The worst failure is salt water in the antifreeze as indicated by test and aluminum components shows corrosion, and usually related to previous symptom of loss of antifreeze. The good news is that the copper nickel version has a much less chance of tube failure because the material is much more resistant to the affects of salt environment than standard copper. Easily twice the life, for nowhere close to twice the cost.
