2 stroke mix (mercury)

[baitdrowner]

Being relatively new to 2 stroke motors, i would like to know what other fuel/oil ratios people are using.
I have a 30HP Merc pull start motor. i have been using a mix of 32:1 to run it in. I now have about 20 hours on the clock and i think its time to change this mix. What do other fellow merc users for fuel ratios?

Hey, I have a Mariner 30hp, i believe it i sthe same motor as yours. After 10 hours on 25:1 i switched to 50:1, as it says to do in the owners manual. Quicksilver Premium Outboard oil TCW-III is the best oil to use for this motor. Joey.

A new Merc runs double oil for the first 10 hrs (25:1)
If it is oil injected (most likely) put 50:1 in the tank and check that the oil res is actually going down. (injection working). Then just use PULP in the tank from then on. If it is not oil injected run 50:1 All Merc/Mariners run 50:1
