Yes sir you are on the money with a V-20. I have a 350 V-8 which suck's up a little more gas. Last trip out to the texas towers I used 75 gallons.
I use addition gas tank installed in my live well. Buy the way the fish move around according to the bait source so you may have to move and burn more fuel! So that leaves me taking along a extra 15 gallons that I safely tie to the deck.
Chuck is correct that a V-20 is on the edge to do a trip like that. God help me if things go to ****! I really don't want to bail with my four man viking life raft and ditch bag.
