#4 is overheat indicator, #3 is oil level ok in oil tank, #2 oil needs to added to tank, #1 oil level low warning indicator.
All the information is in owners manual, go to www.yamaha-motor.com and view owners manual.

I "Mr.Boats Net"
last saturday when I returned from fishing the #2 (oil needs to added to tank) was flashing, but the oil level was ok ! and sometimes the outboard rotation increased from 3800rpm to 4100rpm.
What could it be?

Could be a bad oil level sensor in oil tank or wiring going to sensor. If low oil light comes on then buzzer will sound and engine rpm's will reduce to 2000 rpm's but wouldn't cause it to increase in rpm's. May be a fuel restriction or dirty carbs, could be a loss of ignition on 1 cylinder.
