My first question has to do with my motor. My motor is new, so I was going through the break in recommendations. My boat is a 2001 700LXDC with a 90 hp mercury. The first time I took the boat out I ran it at under 3500 rpms the first hour.....varying the throttle at least every 5 mins. The second time I took the boat out I ran it a bit harder. I had only ran about 10-12 gallons of gas through the engine when the warning "Beep" started souding to add oil.....of course I didn't mean for this to happen....my question is does this sound right? This motor holds 3 liters of oil in the oil injection tank. I thought I could go through at least a tank of gas before adding more oil! Someone with knowledge of engines please reply.
