I've got and had a issue with my closed system and I could use some help.
Ive got twin Mercs both have new risers and manifolds, new pumps and impellers. I did all this before my trip, they were due. Both engines run about the same temp with 115 thermostates (also new) All of you know I baby my 1750hr engines.
I have one reoccurring problem, once in awhile all the antifreeze goes missing from the heat exchanger and the engine runs hot. To hot for my liking but not overheating.
Question is, have I got a cracked tube or more, leaking the antifreeze into the exhaust or raw water? Do I pull the exchanger and have it tested or just replace the thing?
