Per the '79 brochure (http://www.classicseacraft.com/broch...ure/index.html), it may have a 47 gallon tank in it, but that may be for the O/B model. The tank in the Seafari is about 5 gallons smaller in the I/O model because of shorter length due to engine space. The top of my Seafari tank tapers down at the rear on top and the bottom tapers up at the front to allow for removal, so the sides are not perfectly rectangular. It holds about 34 gallons. Later Seafaris with a smaller step down into the cabin, starting about '74, supposedly had a 50 gallon tank.

You might consider having it pressure tested to check for leaks. That could save you the cost of a new tank!

HI Bushwacker,

I just became the owner ( by way of my Dad) of A Seacraft Sceptre 20 ft. it has been sitting around for 10 yr. in my dad driveway. I know it is a classic hull, and Iwould like to bring it back to life. Is it worth it?
