Fuel tank size

[jcking2100]

Hey everyone, New here, so please excuse my lack of forum knowledge & protocol. I am trying to find the fuel tank size on my 2000 21' tracker party deck. I purchased the boat with a Mercury 115 that with self oiler & it unfortunately became cheaper to replace then rebuild so I am currently putting a motor in that has to have mixed gas. There is a significant amount of gas in the tank, so I don't want to empty it to start fresh, but unsure how much oil I need to mix in when I fill it the rest of the way up. I've gotten mixed information when googling, 24 gallon tank on one site & 41 gallon tank on a 2004 model on another site.....Thank you in advance for any assistance.

There is usually, but not always, some type of access point to get to the sending unit on the fuel tank assuming it is below deck. Near the sending unit there should be a tag on the tank with the specs for the tank.
