Slow trolling will load up unburned oil on some older motors. Usually when you accelerate, you get a cloud of smoke with oil and gas stain on the water. My newer etec doesn't do that. There's nearly no smoke when accelerating after trolling for hours. Since yours is 4 stroke, my guess would be unburnt gas.

It looked brown like oil. It is a 4 stroke. . Un burned oil? I didnt think the 4’s didnt burn oil

That's why I said it's likely gas. But if you say it's brown.......best check with a marine mechanic...

I just read this online.
Trolling in cold water might really be the toughest duty your outboard oil will ever see. During extended trolling an outboard may not reach normal operating temperature and even with modern fuel injection and engine controls, unburned fuel in the combustion chamber can condense and migrate past piston rings and contaminate engine oil, a situation engineers call “fuel dilution.” When the motor next reaches its operating temp, that fuel should evaporate as the oil gets hot. But if you troll with a kicker and stow it away to run with a main motor, the oil in the small motor may stay contaminated with fuel. Synthetic oil is more tolerant of contamination by fuel and water condensation. But it’s a good idea to get that kicker up to temp once in awhile.
