Good evening

\ I recently purchased a 2003 Glastron GS209 cuddy with a Mercruiser 5.0 mpi with a Aplha one stern drive 113 hours. I've never owned a newer MPI or an alpha one.
My second trip out we were tubing and I got a beep alarm going off.
Temp & oil pressure looked normal, fuel was dipping below quarter tank.

Could it be just a low fuel warning or does anyone have any ideas?

Mercruiser beep warnings suggest low fuel pressure, but checking to see what anyone thinks??

In the back of the hold there is a resorvoir to the right, not sure if that is the trim pump or the gear oil tank?

That why it starboard or port. Doesn't matter if you looking toward front or back everyone knows what the starboard side is. You describe the trim pump for you hydraulic cylinders on you outdrive. There is also a remote gear lube reservoir on the engine. sometime they fill with much and the float stick to the bottom. looks like there is a level but float stuck on bottom. your year its oil pressure, water temperature or gear lube sets an alarm. disconnect the lube oil reservoir sensor. see if it goes away.

Mercruiser beep warnings suggest low fuel pressure,

Is this showing on the smartcraft display?

Is it a steady and solid beep, or short beeps?

What is the motor serial number?
