it depends on the motor.some of my scott-atwaters('50s vintage)run as rich as 16/1 or 1 pint per gallon.modern motors run as lean as 100/1.check w/ a local dealer as the results of running too lean are expensive.rebuild powerhead isn't cheap.if you want to give it a go on your own i suggest starting 25/1.the worst you'll do is foul the plug(s).

A stoichiometric mixture is the working point that modern engine management systems to achieve in light load cruise situations. For gasoline fuel, the stoichiometric air/fuel mixture is approximately 14.7 times the mass of air to fuel. Any mixture less than 14.7 to 1 is considered to be a rich mixture, any more than 14.7 to 1 is a lean mixture.
A lot still depends on weather you have a 2 stroke or a 4 stroke engine.
Boats with two stroke engines you must consider the 50:1 fuel to oil mix when determining the answer as the oil slows the mix rate of the fuel to air.
