I just bought a 24 foot pontoon boat so I can quit using my dad's pontoon when I go catfishing. Now, I'm looking for a good bait tank to use and I have a few questions. I want to get about a 30 gallon tank that is going to hold blue backs. Where can I place a water pump on a pontoon??? From my understanding the pump has to be below the water level. Can you mount the entire pump unit on the back side of one of the tubes?
