It sounds as tho the oil mixed in the gas could be to much, thus the more smoke. If the motor is run in a barrel, it will create more smoke because the exhaust only can excape from the top of the barrel where as it would not be enclosed if it were on the water. Same goes for the bubbles. JMO

Re: 03 merc 15hp 2 stroke

The 50/1 mix is correct. Some 2cycle oils will cause more smoke than the newer synthedic oils. Use a good certified oil for the motor and it should be fine.Each brand of oil can be somewhat diffrent from others as the additives added at the producer are to the specs of the brand that is ordering them. The use of Sea Foam and Staybile will help keep your motor in fairly good shape and fogging the motor if it will be in storage for a lenght of time should be done. With good maintance of the motor, it should last several years with little or no troubles. JMO
