Re: Evinrude 225 alarm
Take a look at this article, it will help you understand and maintain your VRO system:

Look especially at the maintenance and servicing section. If you have a factory service manual, the purging sequence is pretty clear and straight forward, but needs to be done whenever the tank is cleaned and refilled.
Here's info on purging the oil system that I was trying to find, by Joe Reeves:
(Priming The VRO Pump)
(J. Reeves)
When hooking up or installing a VRO whether it is a new or original VRO pump, it must be primed in order to dispel any air that might be in the oil line.
Have the Oil line attached to the engine fitting BUT detached from the VRO. Add a piece of fuel hose if necessary to the oil line so that it can be aimed into some sort of container.
Pump the oil primer bulb, catching the oil flowing out of the line into the container until you are absolutely sure that you have rid the oil line of every bit of air that might have been trapped there.
Now, connect the oil line to the VRO and secure it. When the oil line is secured, apply pressure to the oil primer bulb ONE TIME only. That's it.
