gas tank dimension for 1989 20 ft center console

[boat_ri_m]

I was hoping to find the dimensions before taking it apart. I want to put in a smaller plastic tank (~45 gallons) since I've been having ethanol problems (I only use about 100 gallons/year plus it's the original tank). So if I knew the max dimensions I could order one since some of the larger plastic tanks have a long lead time.

Thanks for the info.
