Need a little help please. I have a 2001 Proline with a 200 Merc Saltwater outboard. Running to fish on Sunday, the boat started beeping to signal low oil...and that there was. I put a gallon in, but the beeping wouldn't stop. Does anyone know if there is a reset or something? I figured it would stop after I put the oil in. Any info would be greatly appreciated. thanks.

Thanks guys. I'll look into those. The thing was, I was definitely VERY LOW on oil, so I know that when the beep went off, it was legit.
Does the oil tank have a float type devise to guage oil leval and set off alarm?? If so the float could be stuck in the low position since you were low on oil

I'll unscrew the cap and take a look. I assume the float would be inside the tank. Correct? (I'm not being funny...I'm mechanically handicapped!)
Correct, see if you can figure out what triggers the low oil alarm and make sure that it has reset itself now that you added oil.

oil
If you lose flow on the big tank, the little tank on the motor takes over, for the motors protection, it is a backup plan. The motor comes with a sensor for the little tank. You should not be using oil from the little tank, which means the level in that tank should never go down. Troubleshoot and fix this problem with oil flow from the big tank.

Two types of systems, pressurized and not pressurized
I have a 1986 200hp Mercury that has the pressurized system. There are two hoses that go to the big tank, pressure in and oil out. Oil from the big tank is forced into the small tank on the engine so it stays full. If it doesn't stay full, a float switch that is part of the cap sets off the alarm. Make sure that the caps on the big tank seal well, they have to hold about 2psi. There are large O rings in the caps. You also need to bleed the air out of the little tank by loosening it's cap a little until oil starts to overflow and then tightening it. You have to do this with the engine running so be careful, at least that is what the service manual says to do. It is a messy job and you'll need to wipe up a little oil when your done. After you have done this once you'll check the big tank every trip and make sure it doesn't get low again. If this is the system you have good luck.
The other type of system has only one hose going from the tank to the motor. There is probably a primer bulb on this line too. With the motor running pump the oil primer bulb until it is firm and the beeping should stop.

same problem last year
My low oil beeper went off about every 30 seconds. Never had low oil. Finally decided to investigate and after cutting the sensor wire to make sure the beebing would stop I replaced the float insert. 3 or 4 screws on top of the tank and the whole gizmo lifted out. Had a right angle pick up on the bottom so be careful taking it out. Pretty messy even with a low tank. Be prepared to catch and wipe up oil. New sensor solved the problem, I think it was about 60 0r 70 $'s so not that bad and definitly a do it your self job! My engine was 13 years old at the time, a 175 evinrude!
