I am looking to remove the oil injection on my motor. I am kinda scared of Merc Oilers. Is there a youtube video out there showing the procedure or does anyone know of a manual online? Am I too paranoid?

1. The oil injection system utilized on this engine (if PROPERLY MAINTAINED), is VERY durable, and should provide DECADES of trouble-free service. Proper maintenance includes the use of appropriate oil, keeping the oil supply tank CLEAN, and inspecting/checking oil lines AT LEAST ANNUALLY, via the "bend-squeeze-pinch test" method. Replace any lines that are brittle, cracked, or stiff.
2. Don't trust videos found on "detube" as a guide for repairing your engine. Many of them are done by DIY'ers. Get a FACTORY REPAIR MANUAL if you want to perform service on your engine.
3. IF you should decide that you want to remove your oil injection, we can supply you with a FACTORY BLOCKOFF KIT. It's really quite simple- you remove EVERYTHING (tanks, lines, pump, shaft, etc), a blockoff plug in the crankcase (in place of the crankcase pressure fitting), and install a blockoff plug kit, AND a blockoff plug in the VST (where the oil line current connects).

Thanks for the reply. I had a 200 EFI once that had a cylinder go down because of the oil injection and I guess I am "gun shy", maybe I should just leave it on.

Just an FYI: Very seldom does a failed oil pump cause a SINGLE cylinder failure. With the exception of a failed drive gear (transferring debris into one cylinder)- most oil pump failure cause CATASTROPHIC, ENGINE-WIDE destruction.

Don't do it! In the end you have a much higher risk of damage to the motor with it removed. Mixing mistakes, poor control of oil ratio, a lot more carbon build up, shorter plug life, reduced throttle response.
I have been fishing tournaments for over twenty five years and I have never known of anyone that has had a oil injection problem yet!
Thank You Leon Pugh
Agree with all that has been said. The EFI system including fuel management and combination of either separate or integrated ignition/fuel side ECU/ECM both is complicated but yet very reliable. Carb motors are much different as a point of reference. Problem might be related to singular or multiple issue(s), but just changing and removing the EFI system is a mistake IMHO. Probably have a link to the block off,etc, but will await your decision moving forward. Good luck in your decision.
