How can you tell if the oil is being mixed properly? I ask because it does not look like the oil in the tank in the boat is decreasing I've only used maybe 12 gallons of fuel so far, I was wondering if it uses the oil from the canister on the motor first then once that gets low it pumps that canister back full from the main tank? I'm at 50/1 gas to oil now for break in but want to make sure shes functioning right so when I stop manualy mixing she doesn't blow. I would call a dealer$$$$$ $$$$$ just haven't found any honest boat dealers in my area yet.
