Looking at buying a 1972 Crestliner, 17' v-hull. Looks as if it had a built-in fuel cell in the bow (filler cap and vent are still present) but it has been removed sometime in the past. Right now it has two six-gallon plastic tanks in back. No idea on the size of the original tank or it's material (any ideas?), but it sems that it would make a huge difference in the weight distribition of the boat. It has power t/t and planes nicely, but how much of a difference is this going to make handling/safety wise? Is a light front end going to be squirrelly? Should (can?) I try to reconfigure as original? Where can I get some info on max weight, rated HP (currently 115HP Merc), etc (data plate missing). Thanks again for all your help!
