Hi,
I have a basic and general question. My boat (05 Mainship 40 Trawler, twin Yanmer 240's) is on the hard and winterized. I'd like to pull one or both transmission coolers. Of course, they are part of the raw water circuit. When I disconnect the raw water hose from the inlet/outlet of the cooler, some/all of the antifreeze in the raw water circuit will drain. Is this a problem? The engine will be left cooler-less and potentially drained of antifreeze for a few weeks minimum. Is it bad for the other components in the raw water circuit (other coolers, waterpump/impeller, etc) to be dry or not completely filled? The worry would be about losing any corrosion inhibiting benefits of the antifreeze. This seems like an easy cooler to get my feet wet with, but before proceeding I need to have an understanding of whether or not leaving the system drained/partially drained is a problem.
Thanks for any info!
