tank questions
 

As the other post before I have questions on moving tanks. My bottom tank is full of water and who knows what else. I was going to run a single 12 or two. Would this be a problem?

no problem at all as long as you don't run out of gas

Two 12's is only 24 gals.. NOT a lot of gas. You need to give us more info.. are you lake or ocean boating? What size engine? What kind of load? How many people on average?

Fact is most of us carry 40-60 gals for a reason.
