Purchasing a 1998 sea ray 270 with a 7.4 l and bravo 3. The engine has 390 hrs of saltwater use. Can I add closed cooling or is it too old.
Thanks
if it was a freshwater boat, you would have a chance. I put a heat exchanger on my boat before I put it in salt water. However as pointed out, you already have 390 hours in the salt. your past the point of putting on an HX until you replace your motor. and manifolds.
