i have this motor on a 17' 52" bottom flat boat, set up to bowfish, it smokes a tremendous amount while at idle. starts easy, picks boat up on plane in a sec with no bog when you crack throttle. acts like the fuel oil mixture is twice as much as it needs. i have called yamaha and verified the motor being a 50/1 ratio. i have the gas mixed correctly. it has a "fuel enrichment " red lever on side of motor that i have never seen before but i have tried the boat in the "normal" setting and in the "closed" setting and have not noticed a change in the amount of smoke
i have had several 2 stroke outboards but none have ever smoked this bad and run out this good, i would appreciate it if anyone has had this problem and knows a solution.
