Key Components of the Cannon Lake-Troll Downrigger
The Cannon Lake-Troll downrigger consists of several key parts that work together to enable depth control and trolling functionality. Understanding the role of each component is essential for proper installation and operation.
- Reel: The reel is used to spool the cable and is available in lengths ranging from 150 to 400 feet. It is mounted on a shaft and includes bearings and a brake plate to ensure smooth operation.
- Boom: The boom is an 18-inch extension that allows the trolling weight to be positioned away from the boat. It includes a pulley at the end to guide the cable and a locking screw to secure it to the frame.
- Swivel Head and Depth Meter: The swivel head is attached to the end of the boom and includes a depth meter that displays the amount of cable deployed. This allows users to set and monitor trolling depth.
- Weight: Trolling weights range from 4 to 10 pounds and are used to maintain the desired depth. They are attached directly to the downrigger via the cable.
- Cable: The cable connects the weight to the downrigger and must be kept straight and free of kinks to ensure proper function.
- Mounting Base: The base is attached to the boat and serves as the anchor point for the downrigger. It must be securely fastened and periodically inspected for integrity.
Each of these components is described in detail in the official documentation, and their proper assembly is critical to the performance and safety of the downrigger.
Installing the Downrigger
Mounting the Base
The first step in installing the Cannon Lake-Troll downrigger is to mount the base to the boat. A suitable location should be chosen where the downrigger is easily visible and accessible for operation. The base must be securely fastened to the boat using appropriate mounting hardware. Deck plates may be used to reinforce the mounting area, especially if the boat's base material requires additional strength.
It is important to note that the base should be replaced every five years to ensure continued structural integrity. Periodic inspections are also recommended to check for any signs of wear or damage.
Attaching the Boom
Once the base is mounted, the boom can be installed. To do this:
- Insert the boom into the downrigger frame.
- Ensure that the boom is seated firmly against the shoulder inside the frame.
- Secure the boom in place by fastening the boom locking screw (a #8 x 1" self-tapping screw) into the hole in the boom.
The boom locking screw is critical for keeping the boom in place during operation. If the boom is not fully seated or properly secured, it can become dislodged, which poses a safety risk.
Attaching the Swivel Head
The swivel head is then attached to the end of the boom. The process involves the following steps:
- Spread the side plates of the swivel head and slide the assembly over the end of the boom.
- Keep the corrugated spacer in place until the swivel head is fully assembled.
- Once the swivel head is in place, remove the spacer and install two #4 x 1/2" screws into the swivel head to secure it.
Adjusting the angle of the boom head can help control the cable wrap on the reel, so it is recommended to test different angles to find the optimal position for the user's specific setup.
Assembling the Crank Handle
The crank handle is used to raise and lower the trolling weight and must be assembled correctly to function properly. The assembly process includes the following steps:
- Place the thrust bearing between the two thrust washers. The spring should be oriented with the narrow end toward the bearing.
- Slide the bearing, washers, and spring over the shaft.
- Carefully thread the crank handle onto the shaft and turn it clockwise until the clutch is fully tightened.
The clutch mechanism is an important safety feature that prevents the crank handle from slipping during operation. Once the clutch is tight, the handle should not turn forward any further, and the continuous clicking sound should stop. This ensures that the weight is lowered at a controlled rate.
Attaching the Rod Holder
The rod holder is used to secure the fishing rod during trolling and is an optional component that can also be used for rod storage. To install the rod holder:
- Open the holder to allow the rod to be inserted.
- Close the holder to secure the rod in place.
The rod holder must be positioned so that the fishing rod is easily accessible and can be manipulated quickly if a fish is caught.
Operating the Downrigger
Once the downrigger is fully assembled and mounted, it can be operated to troll at the desired depth. The following steps outline the basic operation of the device:
- Reel Preparation: Release some line from the rod and reel so that the lure is positioned 5 to 100 feet behind the boat. This is known as the "drop back."
- Attaching the Line Release: The fishing line should be securely attached to the line release (also known as the Uni-Release). This device allows the line to separate when a fish strikes the lure.
- Setting the Depth: Lower the trolling weight to the desired depth using the depth meter as a reference. This is done by turning the crank handle counter-clockwise to allow the weight to descend at a controlled rate.
- Adjusting the Clutch: Turn the crank handle clockwise until the clutch is fully tightened. This ensures that the weight descends at the desired speed.
- Raising the Weight: To retrieve the weight, turn the crank handle clockwise as quickly as desired.
The Uni-Release mechanism is adjustable and can be set to grip the fishing line with tension ranging from 2 to 22 pounds. This allows users to customize the sensitivity of the release based on the type of fishing and the species being targeted.
When a fish strikes the lure, the line will separate from the release, allowing the angler to take over and fight the fish using the rod and reel. It is important to monitor the depth meter and adjust the weight as needed to maintain the desired fishing depth.
Maintenance and Troubleshooting
To ensure the continued performance of the downrigger, regular maintenance and inspection are necessary. The following tips are recommended:
- Inspect the Mounting Base: Check for any signs of wear or corrosion, especially if the boat is used in saltwater environments. The base should be replaced every five years to maintain structural integrity.
- Lubricate Moving Parts: Apply a light lubricant to the crank handle, bearings, and other moving parts to prevent wear and ensure smooth operation.
- Check the Cable: Inspect the cable for kinks, fraying, or other damage. Replace the cable if any issues are found.
- Test the Clutch Mechanism: Periodically test the clutch to ensure that it engages and disengages properly. If the handle slips or the clutch does not tighten correctly, the mechanism may need to be adjusted or replaced.
If any major components such as the motor or main frame require repair or replacement, they should be sent to Johnson Outdoors Marine Electronics, Inc. in Mankato, Minnesota, or an authorized service center. Retailers are not authorized to perform repairs on these parts.
Safety Considerations
The manufacturer emphasizes the importance of following safety guidelines when using the downrigger. Key safety recommendations include:
- Only use the downrigger for its intended purpose. Improper use may void the warranty and pose a safety risk.
- Ensure that the downrigger is fully seated in the base. If it is not properly secured, it can become dislodged during operation.
- Supervise minors when using the device. The downrigger should only be used by individuals who have read and understood the user instructions.
- Follow all local boating laws and regulations. This includes speed limits, depth restrictions, and other rules that may apply to the area where fishing is taking place.
The manufacturer also provides WEEE (Waste Electrical and Electronic Equipment) compliance instructions for disassembly and recycling. If the downrigger needs to be disposed of, users should follow the appropriate guidelines for recycling and recovery.
