It will be close. Your critical dimension will be the distance between the inner stringers. There are three pairs of stringers in that boat plus the keelson. The original tank deck is flush with or immediately on top of the first (inner) set of stringers. You can see them on either side of the tank deck in Bilgerat's pics.

The inner stringers are the forward extension of the engine beds on a single I/O. In order to fit a 15"+ tall tank in there, it will have to fit between the inner stringers. If the stringers are more than 29 5/8" apart, it may just work. You can probably measure between the engine beds in the engine compartment to see where you stand.
