What do you guys make of this?
Engines are Yr 2000 Volvo Tamd74P. Two weeks ago weather turns cold. Low 30's for 3 days and actually some snow. Water temp is in mid-50's.
While running the engines at idle at the dock just after the cold snap, I notice a distinct sheen of diesel coming out of exhaust on both port and starboard motors (port a bit worse). Both were also running a bit smokey. Nothing crazy but more than normal. Did not seem to get any better as engines continued to idle, perhaps 15min before I shut down. I've never seen the fuel sheen before although, for a variety of reasons, this is the latest I've ever had the boat in. So, I chalked it up to cold weather.
Fast forward about 5 days. Air temp is now warmer, high 50's to low 60's. Water temp the same. I fire up engines again and same sheen. Now I run the boat on plane to my winter storage facility (about 50min underway). But engines run normally, come up to usual operating temp and no unusual smoke on throttle up or at cruise.
But, when I arrive at dock of winter storage facility (approx 10min idle out of channel, 20min on plane, another 20min at idle before docking), sheen is still there when we get into a slip. Perhaps a bit less but still noticeable.
I am still chalking it up to cold since water temp is lowish and it's both engines. But it seems odd that after motors are heated up it would still be an issue.
Curious your thoughts?
