the W indicates its a 98, the manual only refers to motors up to 95 using the loose battery alarm but its a belief that the later models did as well.however my argument was on the C models it cannot as the C model CDI does not have a yellow key on power source nor does it have an oil control module so it cant set any alarms for low voltage.<br /> the jury was hung but swaying my way.<br /> we did have some issues with scale building up inside the block and under the cyl water covers and creating a hot spot, usually happens above 3800 RPM. as does a leaking head gasket.<br /> if after all the other cooling system maint is properly done and your still getting an overheat it may be time to pop the heads,<br /> when the alarm triggers does the engine go into an RPM reduction mode and light any indicators on the tach or speedo ?

there again what part of the CDI on that motor has 12volts going to it?<br />if your CDI has a yellow key on 12V powerfeed it could very well monitor battery voltage, I dont think the C models did but I may be wrong. more

Re: yamaha 115 alarm going off, not overheating

[mkfifo]

Engine Guardian System is activated. Power will be limited. [links]

The Engine Guardian System monitors the critical sensors on the engine for any early indications of problems. The system will respond to a problem by emitting a continuous beep and/or reducing engine power in order to provide engine protection.

Oil Level is Critically Low

Oil lever is low in the engine mounted oil reservoir. Refill the engine mounted oil reservoir along with the remote oil tank. Refer to Fuel & Oil.

The outboard warning system incorporates a warning horn inside the boat. The warning horn may be located inside the remote control or connected to the ignition key switch.

[specto]

Disconnect the pink lead and black lead from the temperature warning sensor on the powerhead. Plug the black lead into the socket for the pink lead. The temperature warning icon should flash and the horn should sound. [links]

The Yamaha outboard alarm system can fail just like any other system on your outboard. Troubleshooting the alarm system includes making sure the horn associated with the alarm works, making sure the warning light comes on and the horn sounds when the oil level drops below acceptable levels and ensuring the warning sounds if the engine overheats. You can even perform the alarm system tests while you are boating

[chris200x9]

Turn the ignition key to the start position and pull the safety lanyard. If the horn is operative, it will sound.

Place a clean container large enough to hold the contents of the engine's oil reservoir below the oil reservoir. Remove the glass sight tube from the oil reservoir and drain the reservoir into the container.

[ellimistd]

Start the engine. When the oil goes below the "Add Oil" level, the alarm should sound. Turn the engine off when the alarm sounds, to avoid operating the engine with low oil.

[friendartiste]

A beeping sound could be coming from a boat for several different reasons, but the most common is because of a fuel restriction brought on from a clogged filter. A clogged filter will slow the flow of gas from feeding into the motor quickly enough. You might notice that while you are holding the throttle down, this is when you hear the beeping noise.

[Aleks]

If the intake pump is not working correctly, because it’s either damaged or faulty, then this could also cause the boat engine to be overheating. Replacing the intake pump is usually a pretty easy and straightforward job, but the most important thing you need to make sure of when purchasing the pump is to make sure you are buying the right model and type of pump that will work properly with your engine.

Check your owner’s manual and see what they say about the different types of alarms and what the causes could be.
