Need the year of manufacture as some 2 stroke units have oil injection that automatically mixes the oil in the correct ratio for engine rpms otherwise it is 50:1 ( 50 parts fuel to 1 part oil)
oil requirements --certified tc-w3 2 stroke outboard oil ---not ordinary engine oil
reference
google --type in mercury outboard oil to fuel ratio

Mercury 1989 60 HP Outboard Motor manual to find gas to oil ratio


50:1 But if your doing mostly low rpm cruising (trolling) then you could reduce that a bit to 75:1 to help reduce smoke. If you do mostly mid to higher rpm cruising, then 50:1 (1 pint to 6 gallons. )
Or 200mls in 20 liters if your Canadian.

What is the oil to gas ratio in my 4 horse Evinrude< Model # E4BRHCOB Ser # B101702


50:1 since the late 60's
Too much oil will gum up the rings, smoke too much and foul plugs. Use ONLY major outboard manufacturers oil, Mercury, Yamaha, Johnson/Evinrude TCW-3. They work the best, and no alcohol fuel.

Fuel ratio for 1968 mercury 9.8 outboard


The fuel ratio is 50/1. Eg.50 gallons of fuel to 1 gallon of oil.
On an older motor and newer cleaner burning oils,you may bring that down to 45/1.Hope this helps

Sounds like your running a bit rich. Try leaning down your air/fuel ratio.
