1. Why Add a Livewell to Your Pontoon?

The concept behind a livewell is straightforward: maintain a healthy environment for fish or bait by circulating fresh, oxygen-rich water. But on a pontoon, that means working within a unique open-deck structure, often with less built-in compartments compared to a traditional bass boat or bay boat. Here’s why a livewell installation is worth the effort:

• Keep Bait Alive & Active: Lively bait means better chances of attracting game fish. A well-aerated environment preserves minnows, shad, or shrimp for hours—or even overnight.
• Regulate Fish Stress: If you plan catch-and-release or entering local tournaments, a stable livewell environment drastically reduces fish mortality and potential penalties from weigh-in disqualifications.
• Dual-Purpose Utility: Some anglers also use livewells as temporary coolers or storage for other items when not actively fishing, optimizing deck space.
• Resale & Versatility: A well-executed livewell upgrade can boost your pontoon’s appeal for future buyers, especially those who appreciate multi-use functionality for fishing outings.

Novelli’s Fishing Edge: While Novelli Pontoon hulls already deliver exemplary stability and performance, adding a thoughtfully designed livewell further cements your boat’s all-round versatility—perfect for families who enjoy both leisure cruises and serious fishing sessions.

2. Determining the Ideal Livewell Size & Design

Livewells come in a variety of shapes and capacities, from small under-seat tanks (5–10 gallons) to larger deck-installed wells (30 gallons or more). Factors to consider:

• Fishing Style & Target Species: Casual panfish anglers can do fine with a modest 10–15 gallon well, while those chasing striped bass or bigger tournament-grade catches might need 30–50 gallons or dual wells.
• Deck Space & Layout: Where will the livewell go? Under a seat bench, in a corner console, or as a standalone deck box? The pontoon’s typical open floor plan can accommodate creative solutions.
• Access & Ergonomics: Ensure it’s easy to open, net fish, or add fresh bait. If the lid is integrated into a seat, confirm there’s a comfortable angle to reach in without contorting or spilling water.
• Shape & Material: Round or oval wells reduce fish stress by eliminating sharp corners. Marine-grade rotomolded plastic or fiberglass resists water pressure and ensures longevity.

Foam-Filled Hull Benefit: Because Novelli Pontoon logs are foam-filled and robust, slight shifts in onboard weight distribution (like a full livewell) are less likely to cause listing or stability issues. This resilience is a boon if you’re adding heavier wells or multiple tanks.

3. Components of a Livewell System

While the tank is the centerpiece, a functioning livewell requires several essential components:

Component	Function	Tips
Tank (Reservoir)	Holds water & fish/bait	Choose size & shape for minimal stress; insulated options help regulate temperature
Inlet/Fill Pump	Draws fresh water from lake/river	Pick a reliable, corrosion-resistant 12V pump rated for marine environments
Aerator/Recirculating Pump	Injects oxygen & circulates water inside tank	A separate or combined pump that ensures fish remain oxygenated
Drain & Overflow	Removes old water, prevents overfilling	Drain line typically out the hull; overflow keeps water level consistent
Switches & Controls	Manage pump cycles, timing, auto or manual modes	Position near the helm or near the tank for quick adjustments
Strainer & Screens	Prevent debris or fish from clogging lines	Check for easy-access screens for simple cleaning
Temperature Control (Optional)	Maintains stable water temps	Useful for sensitive species; advanced setups can include chillers or recirculated cool water

Hint: Many livewell kits bundle pumps, hoses, overflow fittings, and hardware. This can simplify the install process, especially for first-time DIYers. Just ensure the kit’s capacity and pump GPH rating align with your planned usage.

4. Planning Livewell Placement on a Pontoon Deck

Where you situate the tank can impact your boat’s stability, your fishing workflow, and overall convenience. Consider:

• Weight Distribution: Placing a larger well near the center of the boat or distributing dual wells on opposite sides helps maintain trim. A single heavy tank to port or starboard might introduce slight leaning.
• Accessibility & Cockpit Flow: If you frequently net fish from the stern, having a livewell within a few steps streamlines the process. Alternatively, a bow-located tank can simplify front-deck fishing tasks.
• Proximity to Wiring & Plumbing Runs: Minimizing the distance between the livewell and the battery or power source reduces voltage drop. Also, ensure short, efficient routes for intake or discharge lines to the hull side or transom.
• Sunlight & Heat: Direct sunlight can warm the water quickly. If possible, partial shade or under-seat installations help moderate temperatures, reducing fish stress.

Novelli Layout Advantage: Many Novelli models incorporate open deck designs or seat compartments that can adapt to livewell installations. Their foam-filled tubes also reduce concern over moderate shifts in center of gravity. If you’re customizing a brand-new pontoon, consult with Novelli’s design team on ideal well placement.

5. Step-by-Step Installation Guide

Let’s walk through a typical DIY livewell installation on a pontoon boat:

1. Plan & Measure: Identify your chosen spot, verifying enough space for the tank, pump, and plumbing runs. Mark the outline on the deck or seat base.
2. Acquire Your Kit: Gather tank, pump(s), hoses, fittings, a switch panel (or single toggle switch), sealer (marine-grade silicone), and appropriate hardware (stainless steel screws/clamps).
3. Cut or Adjust Deck/Seats: If placing the well under a seat, remove seat cushions/panels. You may need to cut an opening or enlarge an existing storage bin. For deck placement, decide if you need to drill or reinforce for the tank’s bottom or if it’s fully freestanding.
4. Drill for Intake/Overflow: Carefully drill holes for the intake line (below the waterline) and overflow/drain lines. Always confirm hull thickness and look out for strakes, logs, or support beams behind your drilling points.
5. Mount the Pump & Valves: Secure the fill pump externally on the transom or near a toon's underside using a bracket. Connect hoses to the livewell inlet. Attach an aerator/recirculation pump inside the tank or in-line if your kit calls for it.
6. Install the Drain & Overflow Fittings: Fit the overflow tube so water stays at your desired fill level. The main drain usually exits at the hull or transom area. Apply sealant to ensure watertight connections.
7. Wiring & Switch Panel: Route pump wires to the nearest 12V power source. Include an inline fuse or breaker. Many anglers place a toggle switch (labeled “Livewell”) on the helm console. Use marine-grade wiring and heat-shrink connectors to prevent corrosion.
8. Tank Securement & Final Checks: If your tank is under a seat, ensure it’s snug and doesn’t shift. Freestanding tanks might need brackets or straps. Double-check all hoses for kinks or friction points. Seal any deck penetrations with silicone to prevent water intrusion.
9. Test Run: Launch in shallow water. Flip the switch, watch the tank fill, confirm no leaks, and ensure overflow works. Adjust aerator timing or re-circulation as needed.

Novelli’s Foam-Filled Reassurance: While drilling holes for intake or drain lines can be nerve-racking, Novelli Pontoon logs and crossbeams often provide extra structural support. Just follow best practices: measure carefully, use proper sealants, and avoid any major structural members or pressurized foam compartments. If uncertain, consult a Novelli service center or marine pro.

6. Plumbing & Electrical Tips for Reliability

6.1. Plumbing

 

• Use Reinforced Hoses: Bilge or livewell hoses are often corrugated and rated for below-waterline usage. Secure them with stainless steel clamps—double clamp if possible on critical connections.
• Anti-Siphon Loops: Incorporating a loop or vent in the line can prevent water from unintentionally siphoning into or out of the tank.
• Strainers & Debris Filters: If you fish weed-heavy lakes, a small inline filter or removable screen on the intake prevents pump clogs.

 

6.2. Electrical

 

• Marine-Grade Wire: Tinned copper wire and shrink-wrapped connectors resist corrosion. Confirm gauge size matches pump amp draw plus wire length.
• Fuses or Breakers: Each pump circuit should have its own fuse or breaker near the battery for short-circuit protection. Label them for quick troubleshooting.
• Battery Considerations: Livewell pumps can run for hours during an outing. A dual-battery setup or occasionally running the outboard to charge the system can prevent battery drain.
• Switch Placement & Panel Marking: Keep controls near the helm or a dedicated fishing console. Clear labeling “Livewell Fill/Aerator” ensures no confusion mid-fishing frenzy.

 

Automation Potential: If you have Novelli’s AI integration, the boat’s system might manage pump intervals automatically—cycling fresh water to sustain oxygen levels while minimizing power draw. This is especially useful on extended trips where you want to maintain fish viability for hours.

7. Operating & Maintaining Your Livewell

Once installed, daily use and basic upkeep ensure your system stays effective and fish-friendly:

• Prime the Pump: At the start of each trip, run the fill pump briefly to confirm it’s drawing water. Listen for unusual sounds that might indicate clogs or air locks.
• Monitor Water Temperature: Overly warm or stagnant water harms fish. Occasionally refresh with new lake water or run aerators to keep water oxygenated and cooler.
• Avoid Overcrowding: A 15-gallon well can only handle so many fish comfortably. Overloading can deplete oxygen and stress the catch.
• Drain & Clean Post-Trip: Flush out scales, slime, or leftover debris. A simple rinse with mild soap helps control odors and bacterial growth. Inspect the pump intake for weeds or foreign objects.
• Winterization (If Applicable): In colder climates, drain all lines thoroughly, remove or insulate the pump, and store the tank if it’s portable. Freezing water can burst hoses or damage the pump.

Novelli’s Simplified Maintenance: The stable deck of a Novelli Pontoon helps avoid jostling that can weaken hose clamps or stress connections. Moreover, if you’re using the brand’s advanced AI sensors, you might track water usage or detect pump anomalies automatically, cutting downtime and unexpected failures.

8. Tips for Maximizing Fish Health

Beyond mechanical aspects, keep your catch or bait in top condition:

• Use Non-Chlorinated Water: Fill from the same body of water you’re fishing in. Municipal water can harm fish, unless you treat it to remove chlorine.
• Salt & Additives: Some anglers add specific salts or chemicals to reduce fish stress, improve slime coat, or neutralize ammonia. Follow dosage guidelines carefully.
• Periodic Water Exchange: In hot weather, drain part of the well and refill with fresh water every hour or two. This flushes out waste and stabilizes temperature.
• Gentle Handling: Minimizing netting or rough contact inside the well helps fish remain calm. Overly stressed fish can release toxins that degrade water quality quickly.

Catch, Photograph, Release: If you’re practicing C&R, an efficient livewell system ensures minimal mortality. Snap your trophy shot quickly, then slip the fish back healthy—preserving that fishery for the next outing.
