First,Car 54, I agree with you. Second,Ken, I read your comments, especially about the shallow water, and it brought back some not so fun memories! I don't believe that the keel cooler that you describe is used as often any more. That's probably because everyone wants SPEED and the keel cooler will slow the boat down because of added water resistance. I have a semi-Displacement hulled boat with twin four cyl. diesels and the typical raw water-fresh water heat exchanger. The external keel cooler might work well on my boat - except that I would be afraid that I would run it aground and tear off the cooler and/or forget to replace the Zincs and the metal would waste away. ANYWAY- back to the subject. gs, MB is selling marine engines for BIG boats (call them YACHTS) in the U.S. under the name "MTU". So, look up that name and give them a call and maybe they can get some info.. Even MAN is into big marine diesels in this country. Finally, it seems that the Germans are into selling big marine engines and the Japs are into selling smaller marine engines in boats here. Ken, I believe that the Atomic-4 is often replaced with a small Jap. diesel engine when a new engine is needed. Have a nice day. - - - - - - - -
