Today after replacing the Racor filters I started each engine (FL 120's, 1150 hours each) to make sure the engines were properly primed. Both start right away and run well, and did again today. On start there is a lot of smoke and oil which doesn't clear up at idle in the marina.
OK, so I've read a million articles about diesel smoke already and while we're just off a fresh survey I can't help but be bothered by the amount of smoke and "slick" I get from our engines on cold start up.
After all we live in the PNW so oil slicks and smoky boats gather a lot of attention. I also want to make sure I'm treating these very old but very low hour engines well.
Here is what the port engine looks like on cold start:
My question is...dose this smoke look white, blue or grey to you. What should be an otherwise easy question for me turned hard today. I don't know if it was the overcast rainy day, the color of the water behind it or perhaps my skeptical, worst-case-scenario nature but at times it looked like all three to me!
I'd say I smell a strong diesel smell initially followed by an "exhaust" smell after a few minutes. Each engine was run independently and only at the dock. Temps only got up to 120 (as measured by my gauges and an infrared thermometer).
