Pontoon boats have long been cherished for their stability and spacious layouts—traits that make them fantastic fishing platforms. But if you’re serious about angling, a pontoon boat livewell becomes a must. Livewells keep baitfish lively, ensure tournament catches remain vigorous for weigh-ins, and allow you to store fish in prime condition. Adding or upgrading a livewell transforms a casual fishing setup into a pro-level system that maximizes success and convenience.

In this guide, we’ll delve into all aspects of pontoon livewells—from choosing the right capacity and pump system to installation, maintenance, and how foam-filled hulls from Novelli Boats bring extra stability and weight capacity for more advanced or larger livewell setups. Whether you want a simple retrofit or aim for a built-in, multi-tank approach, these insights will help you streamline your fishing routine while preserving the health of both bait and catch.

Top 5 Frequently Asked Questions About Pontoon Livewells

1. How big should my livewell be for a pontoon boat?
   Depends on your target species and number of fish. Weekend anglers might use a 15–20 gallon well, while tournament folks often opt for 30–50 gallons or more, especially for bigger species.
2. Is it easy to retrofit a livewell into an existing seat bench?
   Many seat kits or custom bench compartments can accommodate a built-in tank. You’ll need to add plumbing and possibly route hoses through deck fittings—feasible if you plan carefully.
3. Does a foam-filled tri-log hull affect livewell placement?
   Foam-filling enhances buoyancy and deck rigidity, so your boat can handle heavier tanks or multiple wells without listing. Just confirm overall weight distribution.
4. What’s the difference between a recirculating and fresh water intake system?
   Fresh water intake draws water from the lake, pumping it in/out continuously for oxygenation. Recirculating reuses the same water, using aerators or oxygen injectors. Many systems do both.
5. How do I maintain water quality in a livewell?
   Monitor temperature, oxygen, and fish density. Frequent water changes (or aeration) help, plus removing dead bait or fish quickly to avoid ammonia buildup.

1. Livewell Basics: Capacity & System Types

A livewell is essentially a specialized tank that supplies fresh or recirculating water to fish or bait:

• Capacity Choices: 15–30 gallons suffice for casual fishing. Tournament anglers or bigger species might desire 40–50+ gallons.
• Fresh Intake vs. Recirculating: Fresh intake draws new water from the lake; recirculating systems rely on aeration. Many livewells combine both approaches.
• Aeration & Oxygen: Pumping air or using spray heads to increase dissolved oxygen content. This keeps fish vigorous and reduces stress.

If your pontoon hull is foam-filled, like a Novelli tri-log, you can comfortably handle the extra water weight of a larger livewell, especially if distributing the tank’s location near the boat’s center for better balance.

2. Integrating a Livewell into Your Pontoon Layout

Finding the right spot for a livewell is crucial—common placements include:

• Under a Seat Bench: Many pontoons have seat bases designed to hold a removable or built-in tank. This preserves deck space.
• Console or Helm Integration: Some advanced fishing pontoons incorporate a helm console livewell with side access doors.
• Custom Enclosures: For large tri-logs, you might install a dedicated livewell bench at the stern or bow, especially if you do intense fishing.

Placing the livewell near a mid-ship area can reduce boat tilt as water sloshes. A Novelli foam-filled hull remains stable under shifting loads, but balancing the tank location further improves ride quality.

3. Plumbing & Pump Setup

Livewell plumbing typically requires a through-hull intake, pump, and an overflow drain:

• Intake Placement: Usually near the transom or below deck line. Ensure you mount a sea cock (valve) to shut off water flow if needed.
• Pump Selection: GPH (gallons per hour) rating should match livewell size. A 500–800 GPH pump may suffice for smaller tanks; heavier demand might need 1,000+ GPH.
• Overflow & Drain: An overflow fitting near the top of the livewell prevents water from spilling onto the deck. A drain at the bottom empties the tank.
• Foam-Filled Hull Care: Drilling hull fittings must be done carefully—though foam reduces sink risk, you don’t want improper sealing that invites water intrusion or compromise.

Some boaters add a recirculation pump or timer so water cycles periodically, reducing the chance of fish shock if the boat is moored for extended periods.

4. Aeration & Oxygenation

Maintaining oxygen levels is key for healthy fish or lively bait:

• Venturi Aerators: Basic systems that inject air as water flows.
• Spray Bars: A perforated tube near the top of the tank, distributing water and adding oxygen as it splashes.
• Stone Diffusers or O2 Systems: Some advanced anglers use pure oxygen systems with diffusers, providing higher dissolved oxygen for large fish volumes.

Even with a stable foam-filled Novelli hull, fish can still die if the livewell lacks adequate aeration. Monitor water color and fish behavior—if they gasp at the surface, boost aeration or fresh water flow.

5. Weight Distribution & Stability

Livewells hold significant water weight—8.3 lbs per gallon. On a foam-filled tri-log, you have an advantage:

• Center Placement: Minimizes listing or stern squat. If you place a 30-gallon well off to one side, the hull might lean if passengers gather there too.
• Level Ride: A stable Novelli boat better supports heavier compartments, so you won’t drastically lose speed or note extreme tilt.
• Balance with Gear & Passengers: Encourage anglers to distribute themselves evenly if the livewell is near the bow or stern.

This synergy ensures a full tank doesn’t hamper maneuverability or cause waves to wash over logs in choppy conditions. Checking how the boat sits once the livewell is full helps you confirm safe load distribution.

6. Livewell Maintenance & Water Quality

Healthy fish need clean, oxygen-rich water:

• Periodic Water Changes: In recirculating setups, flush out old water if it gets cloudy or warm. Fresh lake water rebalances temperature and oxygen.
• Temperature Control: If the surface water is too warm, fish stress quickly. Some advanced systems modulate water flow from deeper, cooler lake layers.
• Foam-Filled Hull Calmness: Your stable tri-log from Novelli yields less sloshing inside the well, reducing fish stress. They’re not violently rocked as the boat moves.

Also, remove dead bait or fish quickly to prevent ammonia spikes. A good practice is to lightly rinse the tank after each trip to discourage algae or biofilm from forming.

8. DIY vs. Professional Installation

Adding a livewell can be a do-it-yourself project if you’re handy, but pro installations guarantee precise plumbing:

• DIY Pros: Cost savings, custom seat or console integration, personal satisfaction.
• DIY Cons: Risk of leaks if through-hull fittings aren’t sealed properly. Electrical pumps or timers require knowledge of marine wiring.
• Professional Installation: Minimizes errors, ensures the system is sized correctly for your foam-filled tri-log.

If you’re uncertain about drilling holes in your deck or hooking up aeration lines, consult a marina shop or your Novelli dealer. This helps maintain hull integrity and protect warranties.

9. Storing & Cleaning Between Uses

Routine maintenance after each fishing trip extends system longevity:

• Drain & Rinse: Bait residue or fish slime can spoil quickly, leading to unpleasant odors. Use mild soap or a quick bleach solution (well-diluted) to sanitize.
• Flush Pump Lines: Briefly run clean water through the intake to clear any debris or scale.
• Foam-Filled Log Bonus: Since logs are sealed with foam, minor drips or water spills from the livewell system won’t threaten overall buoyancy. Just wipe up to prevent deck mildew.

A thorough post-trip cleaning routine ensures fresh-smelling seats and a trouble-free start next time you head out. No one wants a foul odor greeting them in the morning.

11. Advanced Features for Serious Anglers

Dedicated fishers often invest in extras that refine livewell performance:

• Separate Bait & Catch Wells: Keep baitfish healthy in one tank, your catches in another. Prevent cross-contamination or predator-prey stress.
• Insulated Walls: Helps maintain stable water temperature in hot climates.
• Oxygen Injection Systems: Instead of just aeration, adding pure oxygen for tournament-level fish care, keeping bass or walleye vigorous for weigh-ins.

If your hull is foam-filled (like Novelli’s tri-logs), you can handle multiple or larger-capacity wells without worrying about major tilt or performance drag. A well-designed system keeps your fish healthy and your boat stable.

12. Livewell Troubleshooting

Common livewell issues have simple fixes:

• Pump Not Priming: Possibly air-locked. Tilt the boat or prime the intake line, ensuring water flows to the impeller.
• Slow Fill: Check for clogged intake screens or kinked hoses.
• Overflow or Leaks: Inspect the overflow fitting for blockages. Confirm all hose clamps remain tight.

On a foam-filled Novelli hull, you won’t face hull infiltration from minor leaks, but water can still pool on deck or saturate seat bases. Quick detection and repair keep the system healthy.
