The following was found in another thread.
Seems to me air fuel ratios such as these in a marine application would be disastrous.

Pay attention here.
Stochiometric (perfect) gasoline air ratio for burning in an internal combustion engine is aproximately 13.7 parts air, to 1 part gasoline, by volume. 13.7:1
A "rich" mixture may be down arround 12 parts air to 1 part gasoline. If I recall correctly, it gets unstable down in the 11's. 12:1
A "lean" mixture, is generally up in the 16 parts air to 1 part gasoline.
Up in the 17:1 range, it again, becomes unstable
A lean mixture has the most air, and allows the gasoline to burn most completely in reality, not under "stociometric book perfection"
Appreciate the input
