I have a 2003 Voyager with 225 Yamaha 4 stroke, the manual indicates I have one main tank with 125 gallon capacity. For some reason, the fuel gauge drops to the bottom bar after about 40-50 gallon consumption, I know because it fills with less than 50 gallons each time. Is there anyway to reset the total capacity or I need to recalibrate the sensor? Thanks!

What kind of gauges do you have? Photo would be great. May be a bad sending unit. GW brochure says 127 gallons standard. Standard sending unit range - 240 ohms empty to 35 ohms full. Unplug sending unit under deck plate - gauge should go to full.

Forget what the manual says... it doesn't "say" anything 
How many tanks do you ACTUALLY have? Do you have more than one deck fill plate?
But if you're saying that the level shown on the gauge acts normal from Full, down to about 1/2... then it drops all the way to E. Sounds like a level sender issue. Physically test the sender and, most likely, replace. Has a dead spot.

Make sure you have your gauge set to the proper protocol for the fuel sensor. There are European, American and one other that I can’t remember available in the settings for fuel quantity on the Yamaha gauges, if that’s what you have. Otherwise you may have a bad sender or some other extra resistance is in your wiring system. Not hard to check with a multi-meter, see many other threads on this forum to help with troubleshooting.
Yup, need to know the gauge style. In addition, answer the following: After you fill the tank, what does the gauge read in bars?
When it drops to a bar, what did it drop from, 5 bars, eight bars , two bars etc.
I think Dennis is right, the sender is bad.
