20 MA Tank Gas Location??
 

My project came without a deck and I do not know where the tank was originally. There are no bulkheads. Could someone please let me know where the original tank was located? Maybe how far forward from the transom? Hatch location, front and back would help if nothing else. Thank you!!!

John, If you are going with a 4 stroke over 115 and a bracket, put it in the anchor locker - Just say'in. Everything else is a comprimise - but so is life!

People want to keep mess'in the the "center of buoyancy" on these great boats that were built for Mark 78 Merc's.

Terry,
I plan to move it forward as much as I can. I want to put a 115 4-stroke Mercury on a bracket (subject to change on a whim!). That weighs about 360#, a little bit heavier than your 90. I would like do a level deck with a 4-foot or so of fish box in the bow ahead of the tank but I don't know if I have enough room. The fish box can go if needed but it would be nice. My tank of choice is a 60" long 55-Gal Moeller tank in it as far forward as I can put it.

I have a 6' long in deck fishbox up front and a 5' aluminum tank right abaft of that on my 18'; moved as much weight forward as possible.
Gave me enough room aft of the fuel tank to make a 30" box for storage/fishbox/livewell.
Also have a flush deck.

Kmoose, Tiny, Fr. Frank, and a couple of others on this forum are of the opinion that Carl had it right in the 60's. "Tight and Light" keeps the center of buoyancy where is is supposed to be. It's fun to mess around with designs if you have cubic dollars, but the ones of us with non-skid dashes that use these great boats to fill our freezers don't fool around with the original design much. We'er in the minority here though, because the dang things are inherently pretty. Don't let me be a sea anchor on your project and you got the right hull - press on Brother - there are plenty of opinions here.
