Johnson GT 200. Oil injector or premix gas?

[Jwhit612]

I have a an '88 Johnson GT 200 outboard on my 20' Glastron Bow-rider. I have been told that those engines are notorious for the oil pump going out and the alarm not sounding which burns up the engine. Is that true? If so, should I just bypass the oil pump all together and just pre-mix my gas and oil?
If I did keep using the pump how would I know if the pump quit working before the engine blew up?
Thanks in advance!
Jeff

Check out the "Top Secret File" at the top of this forum, and the Engine FAQs Forum for discussions and instructions, Jeff.

Good luck.

cap off your vro pump on the oil inlet...and premix for goodness sake..as JB mentioned the exact process is in the secret file section. I will never understand why they built motors with an oil injection system just seems like a disaster waiting for a place to happen to me. its not like they have ever ever ever built a perfect motor that had no mechanical break downs, they all need some part or another replaced eventually.

VRO conversion w/ pump still working

if the fuel side on your Pump is still working it is very simple. unplug the 2 line harness going to the oil tank, unplug the 3 or 4 wire harness, going to the Vro pump. cut and cap the oil line going into the motor. add oil to fuel tank, mix well, then remove fuel line at top carb, catching gas in a container, pump the fuel line bulb until you get premixed gas to the carb. you can tell as it will change color. put line back on carb, and go boating.
