Hi Captpete,
The 55 gallon Moeller I presume is a belly tank?? It will fit front to back depending on what V 20 you have. (I have an 84 v20 OB cuddy) It will not fit under your floor hatch due to the deadrise of the V20, (about 22 degrees) and the angle of the Moeller belly tank is about 12 -15 degrees. I did not find a ready made belly tank that would fit under the floor over about 30 - 40 gallons due to the deep-vee deadrise angle and the belly tank bottom angle. If you need 60 gallons of fuel, the only way is to have a custom aluminum tank fabricated. An aluminum 60 gallon exact v20 replacement tank can be fabricated for about $500-$600. (In NJ) The replacement tank drawing with exact dimensions is somewhere on this website!! Do a search on "fuel tanks".
