!st time out this season. Last season no problems. Ran motor in yard for a while, no problem. Got about 1/2 mile from ramp running slow 1500 to 2000 rpm and horn and lite came on. Couple of pumps of oil primer bulb got light off once but came back on and continued back to dock in SLOW mode. Will check fuse for oil enjection system and flow by disconnecting oil line as per evinrude ops manual but if no luck any suggestions. Oil filter never changed. 184 hrs on motor.
