Re: Priming the Oil?
I have a 2002 Mercury 125 with oil injection
I just installed it and someone said that the oil system had to be "primed"
This is my first oil injection motor and have no idea if this is true and if it is true,
how do I prime it
The motor was shipped with no fluids in it and I'd rather not burn it up on the outing
Thanks
Assuming it's all installed and hooked up.
1. Fill the tank on the motor, and put an adequate supply in the boat tank. It doesn't need to be plumb full.
2. Mix oil in the fuel to 50:1. It's a good idea to use only part of the tank for it, like 5 gallons in a 20 gallon tank.
3. With cooling water supplied, either at a dock, in a tank, or with cuffs on, start the engine and idle it. Then slightly crack the cap on the engine tank. It should overflow soon. Tighten the cap, clean it up, and yer good to go. Don't overtighten the cap, just tighten it enough to staunch the leak. Overtightening will eventually crack the cap, and they're expensive.
Run the 50:1 till you're sure it's oiling right. Then you can just add gas to the main tank. A little oil there won't hurt a thing.
If it's using oil, and no alarms sound, she's good to go. It should give you a diagnostic beep (i'm here) when you turn on the key. If someone has messed with the engine, check the alignment of the oil mixture lever on the oil pump to be sure it's mixing the right amount for the throttle setting.
hope it helps
