75 tsunami

[PackRat]

Agree with no foam. Appears my ‘75 23 Sceptre twin I/O had original tank that was only screwed into strringers with tangs on top - no sign of foam. Date on label looked like 1974 but hard to read. Some pitting at rubber strips it rested on but generally in good shape for 44 years. Dims were 51” long , 28” wide, 12” tall. ~ 72+ gal. Im converting to bracket / outboard and increased volume to ~100 gal so length grew to 70 inches.
