Bruce. Fond the highest point with a hose and.pour.coolant in there. You will be surprised how much it will take. On my 3QM it is the heater house feed to heater.

Is it slowing down at all? If so, you may just not have "burped" the system sufficiently when you replaced the coolant. Some cars were notorious for that, which is some cases caused problems down the road.

When I changed the coolant last year, it seemed like about 12 oz less coolant went back in. Since then. I've noticed the overflow tank seems to be dropping a little, and I've topped it off 3 or 4 times. In total, I've probably added 16 to 32 ounces of coolant. The exhaust exits the boat downward, so I don't get a good view of the existing exhaust, but I'm not seeing evidence of steam as I would expect if I had a head gasket leak. The oil looks fine. There's no evidence of oil in the coolant. There's no evidence of coolant leaking externally ( ie orange in the engine bilge). We get the boat off the dock 4 to 6 times a month, each time motoring about an hour per trip (30 minutes out, and 30 minutes back in after sailing. I've only owned the boat about 18 months, so there could have been a preexisting condition. Any ideas, and is there a way to figure out what is going on? Should I be worried? Thanks! Bruce Whitmore
