Installing a downrigger on a pontoon boat can transform your fishing experience, especially for targeting species like Kokanee salmon that thrive at specific depths. A downrigger is a specialized device that lowers a weighted ball (typically 6-12 pounds) into the water, allowing you to precisely control the depth of your fishing line. For pontoon boat owners, the installation process requires careful planning due to the unique square railings and deck configurations. This guide provides a detailed, step-by-step approach to installing a downrigger on your pontoon boat, covering equipment selection, mounting options, installation techniques, and maintenance tips. Whether you’re a seasoned angler or a beginner, this article will equip you with the knowledge to set up your downrigger effectively.
Why Use a Downrigger on a Pontoon Boat?
Pontoon boats are prized for their stability, spacious decks, and versatility, making them ideal for leisurely fishing trips. However, trolling for fish like salmon, trout, or stripers often requires precise depth control, which a downrigger provides. Unlike traditional fishing methods that rely on weights or divers, a downrigger ensures your bait or lure stays at the desired depth, even in deep lakes or reservoirs. This precision is critical for species that inhabit specific water columns, such as Kokanee salmon, which are often found 20-40 feet below the surface.
Downriggers also enhance the pontoon fishing experience by allowing you to:
- Maintain consistent trolling speeds without affecting bait depth.
- Fish multiple lines at different depths using stacker releases.
- Reduce physical strain compared to repeatedly casting and retrieving heavy weights.
Choosing the Right Downrigger for Your Pontoon Boat
Selecting the appropriate downrigger is the first step in the installation process. Downriggers come in two main types: manual and electric. Each has its advantages, and your choice will depend on your fishing needs, budget, and boat setup.
Manual vs. Electric Downriggers
Manual Downriggers:
- Pros: Affordable, no electrical wiring required, easy to install, low maintenance, ideal for shallow to moderate depths (up to 40-50 feet).
- Cons: Requires physical effort to crank, less convenient for frequent depth adjustments or heavy weights (12 pounds or more).
- Best For: Anglers fishing in smaller lakes or reservoirs with moderate depths, or those who prefer simplicity and cost savings.
Electric Downriggers:
- Pros: Effortless operation, ideal for deep water (50+ feet) or heavy weights, faster retrieval, advanced features like bottom tracking or programmable depths.
- Cons: Higher cost, requires battery and wiring setup, more complex installation.
- Best For: Serious anglers fishing in deep waters or those seeking convenience and advanced functionality.
For pontoon boats, manual downriggers are often sufficient due to their simplicity and compatibility with the boat’s limited electrical systems. A popular choice is the Cannon Uni-Troll 10 STX, which offers a 2:1 gear ratio for smooth cranking and a robust build for durability. Priced at approximately $349.99, it’s a reliable option for most pontoon anglers. For those preferring electric models, the Cannon Magnum 10 STX (around $599.99) provides effortless operation and is suitable for deeper trolling.
Key Features to Look For
When selecting a downrigger, consider the following features:
- Gear Ratio: A 2:1 gear ratio (or higher) ensures smooth and efficient cranking for manual models.
- Boom Length: A 24-36 inch boom is ideal for pontoon boats to keep the weight clear of the hull.
- Weight Capacity: Choose a downrigger that can handle 6-12 pound weights, as these are common for freshwater trolling.
- Mounting Compatibility: Ensure the downrigger includes or is compatible with a clamp or rail mount for square railings.

Mounting Options for Pontoon Boats
Pontoon boats typically feature square railings (1-1.25 inches) and spacious decks, which pose unique challenges for downrigger installation. Unlike traditional fishing boats with flat gunwales, pontoon railings require specialized mounts to secure the downrigger without drilling or damaging the boat. Below are the primary mounting options:
1. Clamp Mounts
Clamp mounts are the most popular choice for pontoon boats because they attach directly to square railings without permanent modifications. The Cannon Clamp Mount (Part No. 2207327, ~$89.99) is designed to fit railings up to 2 inches wide and is compatible with most Cannon downriggers. It’s made of machined aluminum with a powder-coated finish to resist corrosion.
Installation Steps:
- Position the clamp mount on the railing at your desired location (typically near the stern for easy access).
- Tighten the clamp screws using a 7/16″ box end wrench, ensuring a firm grip without over-tightening.
- Attach the downrigger’s base to the clamp mount using the provided bolts and a #3 Phillips screwdriver.
- Apply anti-seize to the bolts to prevent corrosion.
2. Rail/Side Mounts
For boats with narrow railings or T-joints, a rail/side mount (e.g., Cannon Rail/Side Mount, Part No. 2250940, ~$79.99) provides a secure attachment point. This mount is ideal for pontoons with limited deck space.
3. Pedestal Mounts
Pedestal mounts elevate the downrigger for better reach and visibility. The Cannon Aluminum Fixed Base Pedestal (Part No. 1904030, 4″ height, ~$99.99) or Swivel Base Pedestal (Part No. 1904032, 4″ height, ~$129.99) can be bolted to the deck or mounted on a track system. These require drilling into the deck, so ensure your spouse approves to avoid domestic disputes!
4. Track Systems
For maximum flexibility, consider the Cannon Aluminum Mounting Track System (Part No. 1904025-1904029, 6-36 inches, $49.99-$99.99). This system allows you to slide and lock downriggers, rod holders, and other accessories along the track, making it easy to reconfigure your setup.
