1995 Johnson Ocean Runner 60 deg. V6 150 hp<br />Engine runs great, but on our last outing the oil warning horn sounded and we shut her down. Checked oil resevoir. It's capacity is 1.8 gal. It took about 2 thirds of a gallon. Engine cranks up fine and we are on our way, no excess smoke, all normal.<br />Later on we crank up full bore to pass another boat and horn goes off, same drill, topped off the tank with the remaining third of a gallon just to be safe. All's fine for a while then horn again. This time oil is still full. We crank up and putt back to landing, trailer and home. What do you guys think?
