I have a 1990 Mariner 75 HP (serial 0B361162) that has an oil injector still connected and is still working. I plan to disconnect and go with premix fuel. Please note the topic of this post, Not a discussion on whether or not to disconnect but rather is a kit needed or available to bypass the oiler and premix fuel.

After researching posts it appears that some motors had a kit that allowed the complete removal of the pump and with a plug that replaced the shaft and kept everything in its proper place.

There appears to be no warning on this engine other than the low oil sensor in the tank. If someone knows that this engine has a motion sensor on the oil shaft I could be easily convinced to leave it alone, otherwise it is going to be history.

Should a kit be available a part number and supplier would be much appreciated. I would like to remove it as a precaution as this engine is 20 years old and is rarely ran at anything less that 3/4 to WOT. I have not been able to even confirm that such a kit even ever existed for this motor.

No motion sensor on thoses, only low oil and overheat sensor. You could simply remove the cover, pull out the shaft and replace the cover, or even letting the shaft there. Then disconnect the wire from the tank to the module and you're done.

There's no need for a kit. Yes, the empty tank will induce air in the fuel line but it's nothing that you'll ever notice or that will restrict fuel flow to prevent operation (2% of air that will escape at the carbs).
