Balancing Weight in a Jon boat

[JerseyFisher]

So I have this 12' job boat that has undergone modifications over the past year or so, including a casting deck with a seat and trolling motor. The big issue now is that when I move to the front of the boat to man the trolling motor the bow dips down and is real close to the surface of the water.

As a temporary fix, I put a couple 50# sand bags in the stern next to the engine. Do you guys have ideas for permanent solutions of evening out the weight while I'm up on the casting deck?

Here is the boat, just to give ya an idea: http://www.bassfishin.com/bassfishin...ghlight=jersey
