I have a 2000 125hp mercury oil injected 2 stroke. The motor runs fine but everytime I park the boat I come back to a puddle of oil that leaked all the way down the lower unit. So I took the carb cover off and ran the motor with the hose hooked up to it. After about 5-10min of running it I stopped and about 10sec after I stopped the motor, oil started running out of the bottom carb. It is a pretty decent amout of oil. I brought the boat in and they replaced some check valves after they gave me the run around and had my boat for a month.

Does the engine run good?

Is it leaking out of the fuel bowl?

Floats sticking?

Carbs rebuilt?

Inspect all hose for a leak?

Clean motor, run on muffs, shut off and follow leak.

Also find out if mechanic changed both check valves.

The engine does run good. Carbs have not been rebuilt. Both check valves were changed.

How do I tell if the floats are sticking?

Re: Bad Oil leak out of bottom carb

If the float or seat are sticking it will cause the carb to fill with to much fuel and cause a flood or overflow condition. Normaly it would purge from a vent hole on the carb. You could also check the sparkplugs for discoloration.

You could try running some seefoam throu through the fuel. See Decarb threads.
