Fuel tank capacity ( original ) for 23' Tsunami

[abl1111]

I lost the measurements I took of the tank before I epoxied it and re-installed... I think the capacity is 65-75, but want to know exact.

What is the gallon capacity of a stock/original 1975 23' Tsunmai w/ an I/O ?

Thx...

I had a 1977 Sceptre I/O and if memory serves me right it was an 85 gal tank with 72 useable. Somebody that has one will probably chime in.

My '75 Sceptre inboard has a 72 gallon originally but it was squashed in and in my opinion too tall at the fill neck, it was touching the bottom of the deck plate. I shrank mine in height a bit and lost 8 or 10 gallons.

Thx for the response. When I re-cored my mushy hatch, I grinded a deep depression into the 3/4" ply wood directly over that pick -up; it was a concern of mine too. I just used a few extra layers of mat there. I have a nice clearance - no problem.

I gues'timate my tank to be at about 70ish, but the # of 65 gals is in my brain for some reason !?
