Too little fuel, to much air, which can cause engine overheating. ~

Not Just a boat. If you run an engine to lean you create a situation in which the engine is not receiving enough fuel in relation to air. It will tend to run hotter or have pre-ignition. Both are a sign of impending repairs. Check your plugs, they will tell you. Take it out for a run (20 min) and shut it off on the lake, out of the way. Pull a plug and look at it. It should be tan-light brown. White=lean. Black=rich

As with any engine this means you are not getting enough fuel.Running rich means you a getting to much fuel.Running too lean will cause lack of power and the engine could overheat.

Too lean means not enough fuel mixing with the air, resulting in poor combustion and loss of power.

are you talking about a 2 cycle engine?.........to run any engine too lean can increase combustion chamber temperature & reduce power.....in a 2 cycle engine this can destroy the cylinder wall,s as well as the piston.

Toomuch air in the intake mix. It can cause heating in inboard motors and warp valves. Doan no bout outboard.
