Fuel Gage and Fuel Remaining

[Have Fun Today]

I have a 1997 Chaparral 2335SS with Merc 5.7LX, all factory original....

I'm trying to gather some fuel flow data and I'd like to know how much fuel I have burned after each outing without filling the tank back up. I check the fuel gage on the trailer before and after using the boat. My manual says the tank is 75 gallons.

1. What is the shape of the fuel tank? Is it smaller towards the bottom (which would make the fuel gage go down faster on a lower tank)?

2. Does this mean that at half full on the gage, I have 37 gallons remaining?

3. On E, how much fuel remains in the tank?

Thanks

Re: Fuel Gage and Fuel Remaining

I'm planning on adding a Flowscan device to my Signature 240. These devices can replace the existing tach instrument, or stand alone. Fuel management is much easier with this kind of device. The 7000 or 9000 series gas models will do the trick.
