95 MERCURY oil injection, keep it or ditch it?

[THEFERMANATOR]

The pictures are the result of the previous owners 6000RPM+ pass running it at 100:1 pre-mix :o, not a pretty site. It actually looks better in the pictures than it really is. I've always had good luck with the MIKUNI oil injection pumps, but I have a bad gut feeling about the 2 piece plastic crank gear. I guess it decided, ditch the oil injection and run it 50:1 and live with some smoke ;D. On the bright side though, it had a full 3 gallon oil tank filled with QUIKSILVER oil when I bought the other boat for it's engine.
