1996 Johnson 200 hp ocean runner. No oil light is illuminated whenever the key is on. Vro pump is 2 years old, Dealer told me it is probably not the punp. System check tach is was replaced six months ago. I was told the light should only come on if motor is running, and not just with key on. Ten secong horn does sound. I am running the motor with a spare gas can that has a 50:1 oil mix in it and the motor is smoking a lot. It appears as if the pump is pumping oil giving me a combined fuel oil ratio of 25:1.
