a friend of mine just bought this boat, and has had it out 2 times so far, at full throttle runs great nice and smooth no issues, but at trolling speed this thing really fogs for mosquitos. it has an oil injection system( i dont care for personally) on it, but thats besides the point, can he (we) eliminate this and just mix the oil and gas so we know for sure that its getting the correct mix, we burned up 4 gallons of gas and it used 1 quart of oil, i havent sat down to really figure out what ratio that works out to but it stalled several times trolling, afraid its gonna foul plugs and be a real pain to fish outta, if ya got any tips or even know what possibly wrong with it any help would be greatly appreciated,
