1988 23' Mako Fuel Tank Dimensions

[jsherlax36]

In the process of buying a third Mako that needs some work - Most importantly, we need to replace the tank. Does anyone have a drawing of the tank that can be shared?
I believe tank is 115 gals for that vintage boat and it is flat bottom form what I can find so far / we will definitely use the old tank for comparison, but just trying to get ahead a bit
Thanks

Your best bet is to pull the tank, get some measurements and call Sunshine Marine tanks in Fl. You would not want to build a tank off someone's measurements off the internet
