Also I’m not sure about the prop shafts spinning. Didn’t check for that when I was on the boat. If they were spinning it would have been very slowly since I was anchored with the engines on all day (didn’t want to risk a battery failure before I have that figured out) and would have noticed if they were spinning enough to move the boat.

Sorry–no work has been done since it was working fine the last time I had the boat out. Four months ago I had the engine oil/transmission fluid and filters changed, as well as the spin-on fuel filters and Racor filters. Also serviced aftercoolers. As I mentioned, been a couple years since I’ve had the airseps cleaned.

Don’t have any recent pics. Will be a week or two before I can make it down there to take some.

Maintenance is all up to date, but I haven’t cleaned the airseps in about 2 years (wondering if that could cause this).

Another potentially relevant fact–the morning this happened the batteries were low and I needed to run the generator to get the batteries to the point where the engines would start. Something’s wrong with my charging system and I’m having that looked at. Left the boat running all day while fishing (didn’t want to shut them off and risk another battery issue) and the attached pics of the Diesel View displays were toward the end of the day before heading home from Catalina. Could something with the batteries affect this issue?

Thanks for the responses (didn’t have the email responses box checked so didn’t realize there were responses). Will try to get better pics soon and check out the sealant stuff.

Ok next time on the boat I’ll take pics.  The problem is stbd engine every now and then loses coolant.  Some trips not an ounce is lost, and other trips close to a quart.  No correlation with running the engines hard or not.  Both caps are new but I can try switching.

Thanks Tony.  I just replaced the caps a few months ago with new ones (from sbmar).  Anything else I can do?
