My friend has an 88' 135hp black max merc. He replaced the plastic drive once before and some other components but now it is starting to act up again and he rather just premix and forget it.

My engine came with the oil injection pump already removed so I really don't know the procedure. Is there a plug kit available? What are the steps for removing?

I know that we have will have to get rid of the warning module (lubalert), I am really just trying to figure out how to button this guy up properly.

There is also a thread under titile of removal ov VRO , bach in June, I found it under the search function. Found it again: http://forums.iboats.com/showthread.php?t=201604&highlight=oil+pump+repair+kit

Keep us posted on the exact procedure when you figure it out for sure. I am running a 1989 200, expect some day I may need the info myself.
Found this also:
Print this out and save it. This is your official Laser EFI Oil Injection Removal Guide, courtesy of yours truly:

Remove both oil tanks and hoses. Pinching the hose to the oil pump with vise grips will lessen the oil mess. Disconnect oil cap wires from module. On some motors, you have to temporarily remove the ECU and upper bracket to remove the oil tank. No big deal.
Remove pump rotation sensor. (has 3 wires)
Remove "oil warning module." Disconnect it from anything it was hooked up to.
You might as well remove the water detection module on the front of the motor while you're at it. It relies on the other module to warn of water in the fuel. Check your filter more often now.

Since the small bolts that hold the oil pump on may be hard to access on your motor, you will probably need to take out the bolts that hold the vapor separator on, and remove some fuel lines and a couple of small bleed lines to move it. You'll be able to swing the assembly slightly out of the way to access the oil pump's bolts.

Remove the oil pump, and the magnet & shaft assembly behind it.
Slide it out, and replace it with the plastic blockoff (you have this, right?) There should be an o-ring on its shaft detent. Flat side of the shaft faces the crank. This plug will prevent the bushing from falling out inside your crankcase.

The "incoming oil" fitting on the vapor separator is a check valve. If you simply remove the hose from the barb, it will probably be fine. You can replace the fitting with a plug if you want.

The "outgoing air pressure" fitting on your block is also a check valve, but it needs to be removed and replaced with a threaded plug.

The blockoff kit will include the special plug, o-ring, 2 screws, and a threaded plug.
