Fuel Indicator Light - SC 21

[Phoenix]

Hi All - I am a new user to this site and a new SeaCraft owner. I bought a 98 21 CC Master Angler with 150 optimax (original) that has less than 40 hrs.

Only had the boat a short time so admitedly I need some getting used to, but wanted to ask about a possible issue. I had the motor worked on extensively and it checked out fine a few weeks afo. On my second trip out, the fuel light stayed on and an alarm sounded about every 4-5 minutes. Now I don't have a ton of fuel in there, maybe 20-25 gallons of a 95 gallon tank so this might just be a low fuel warning, but i wanted to check with other owners to see if this is in fact a low fuel alarm or some alarm sensor for something else.

I am planning to put soem fuel in and maybe that will cure the alarm issue, but just not used to an alarm going off for low fuel so I returned back quickly.

Anyone else know if these boats have a low fuel warning?

thanks
