Last Sunday I had to take the boat of of the boatshed she was in for the winter so I decided to go for a slow spin around the bay. About maybe 15 minutes into the run I noticed the exhaust go from its usual steamy white vapors to much darker dark gray colour which seemed to stick around longer than the usual vapors. As soon as I noticed the changed I brought the throttle down and the dark exhaust didn't show up. I decided to head back to port fearing a breakdown (single engine). I was able to get a lighter shade of gray on the way back, at higher rpms, around 1800rpm. The engine was only running at about 1800rpm when it started to produce the darker exhaust. I will try to get a picture I took of the lighter gray exhaust but the ones I have aren't that good.
About a week before moving the boat I had my had the oil changed out of my FL120, as well I had the impeller changed and the injector pump oil changed. We ran the engine for a little after changing the oil but not under load. I am just curious to see if any of you maybe able to suggest a possible cause or even say whether this is a serious problem or a normal thing. In all time using the boat I have never seen this happen before. All gauges seemed to be reading what they always read at those rpms.
I will be consulting the mechanic who did the work as we were going to sea trial and test the rpm's anyway at a later day and after purchasing a new water pump cover plate.
Thanks
