I have an issue with oil leakage on my 2000 Mercury 225 OptiMax. Leakage on left side below impulse fuel pump some where. I just cleaned with engine degreaser and hosed off, I'll run it tomorrow in back to see if i can pin point that leak. But I did find a leak on my oil injection pump, lower right corner of pump if your looking at it from the front of motor. Right by the lower hex bolt. Can I rebuild or replace o-ring or seal in the oil injection pump? I haven't found any documentation or videos on such a process. Any and all help appreciated.
