continuous tone = either temp sensor or a short in the system, which could be in the wiring, the ot sensor, or the oil module. [links]

Before you run it one more second, mix oil with your fuel at 50:1. If it's not oiling, you'll save your power head. If it is oiling, you'll gum up a spark plug after awhile maybe.
beeping is from the oil alert. It could be fault input signal, including the engine mis-firing, a faultly oil alert module, or a true alarm because it is either low on oil or the pump is not turning.
My Mercury 150 hp alarm is sounding off after 30 to 45 seconds of run time. Started this year after sitting up all winter. No problems at the end of last summer. The main oil reservoir is 3/4 full and the small resevoir on the front top of motor is full. Cranks and runs great. Water is "peeing" out of the pee hole after about 30 seconds of running then high pitch alarm sound coming from shifter area sounds. I just shut her down. Can I mix some oil in the gas, run it for a short time, and see if the alarm goes off or the oil level goes down in the resevoir?
It could be the temperature sensor. Give it a check. more
Don't the types of beeps signal the type of problem? If so, check the owners manual. This should help narrow down the problem. here
Next, grab a factory manual and start reading about the security system. There may be a troubleshooting section that will help you get rid of the problem. In the worst case, you can modify the sensors or harness to prevent the alarm from ever triggering.
Although there are many possible vehicle security systems, the basic design is the same.
If there is oil, grime, or dirt on the sensor, try cleaning it by gently scrubbing it with brake fluid and drying with a microfiber cloth. If the problem persists, the sensor may need to be replaced. here
The alarm module is the security system-specific computer. Some drivers prefer to install an aftermarket alarm system, but either those or factory systems can be installed incorrectly. [links]
These are really only used in very advanced systems, like in expensive vehicles. They can detect when someone is too close to the car and give a pre-recorded verbal warning. more
If one of the sensors is not properly connected to the computer, signals can get weird. First try disconnecting and reconnecting the hood latch sensor as that is often the culprit. If the other sensors are accessible you can do the same for those. here
Finally, if you OPS alarm is going off, you should be getting a Code 39 on your YDS. I don't understand why you are not.
I have three 2005 F225s. I've had to replace two OPS at 450 hours on two engines as they failed. I got a code 39 on both. The replacement OPS was from a Yamaha dealer (SIMs up north), and they were expensive, and they had a much bigger hex nut, as Yamaha has had issues with these OEM sensors.
You definitely want to know what your oil pressure is on that engine. The fact that your alarm goes off at low speeds may or may not mean much. mine went off at high speeds when they failed, and all the time on start ups after that until I replaced the senders. here
One of the mechanics (Rodbolt17, Boscoe, so on and so forth) may be able to solve your OPS alarm issues, and I wish you luck. [links]
The mechanic put your engine on his YDS and says the oil pressure is good, but if the alarm is going off all the time, you need to find out why. more
I have the Yamaha YDS and can put my engines on a laptop and read the oil pressures any time I want, and that might be a good investment for you for a few $100. The YDS is useful as it will tell you what is setting off every hard code and every alarm. I purchased an oil pressure gauge from Andy as he was able to find one Andyjr@shipyardisland.com here
If you are not familiar with the workings of your system, or do not feel comfortable checking the system on your own, we would suggest calling your local service provider to figure out the issue. more
A common misconception is that a high level alarm on a septic tank indicates that the tank needs pumped out. A high level alarm will not indicate when a tank needs pumping, and while pumping the tank out may resolve the alarm in the short term, once the tank fills back up the alarm is likely to re-occur because the main problem with the system has not been resolved.

Aerobic Treatment Systems usually consist of an aeration device that can be an external air pump or air compressor, or an internal unit such as a shaft aerator or a submersible aerator. The cause of an alarm on aerobic systems is either the failure of the aeration device or high water level inside the tank. If your alarm or control panel does not indicate which alarm is active, below are some steps to help identify the problem. [links]
If you are getting an alarm from your septic system, obviously something is wrong. In this Knowledge Base article we will go through the most common causes of a septic alarm and how to check for them.
