Question about Mercury Boating
The only way to do that is to replace the fuel pump module assembly in the fuel tank. The filter is built into the module.

sounds like a relay or other electrical device is noisy , only way to find out is to strip out instrument panel and try to locate the 'noisey' item, a good place to start is the fuel gauge as they have a resistor build in and they can cause a buzzing when the are getting worn out , fault finding at it's best , good luck and take your time and be patient and keep me posted if you wish

4 beeps every 2 minutes has 2 causes:
1) LOW oil level in the engine mounted reserve tank ( fill it up manually )
2) Water in the engine mounted water separator/fuel filter ( clean out )

SOURCE: 2011 Mercury optimax. At 3500rpm alarm goes off and goes in guardian mode. Water pump and pressure good. Oil level is good. Oil pump working correctly. Changed internal pressure regulator. Any advice?
This could be a lot of things. Have a computer scan done to see what the issue is. Could be a bad poppet or water pump. There is a sensor in the oil tank that can cause this too. Also the throttle sensor.
