While some repairs can be performed by boat owners, more serious issues may require the assistance of a professional marine construction specialist or electrician.

Fixing a drifting boat lift platform

A drifting boat lift platform is a common issue with hydraulic boat lifts. There are a few possible reasons for this, and some simple fixes you can try before calling a boat lift repair technician.

Firstly, air in the system can cause the platform to drift down. To resolve this, simply cycle the lift up and down a few times to remove any trapped air. This is a good first step as it is a simple fix that can save you time and money.

Secondly, check the oil in the reservoir. The oil level may be too low, or the oil may be contaminated. If the oil level is low, top it up, and if it is contaminated, change the oil. This is a more serious issue, and if you are unsure about how to do this, it is best to contact your boat lift dealer for assistance.

If the above solutions do not work, there may be a more serious issue with your boat lift. Contact your boat lift dealer, who can assess whether oil is seeping past the lift cylinder. If this is the case, then your lift tube and control valves will need to be checked and possibly repaired or replaced.

It is important to address any issues with your boat lift as soon as possible to prevent further damage and ensure the safety of your boat. While some issues can be resolved with simple fixes, others will require the expertise of a professional technician.

Repairing a noisy boat lift

A noisy boat lift can be a real nuisance and can be caused by a few different issues. Firstly, it could be due to insufficient lubrication, particularly if the boat lift is an older model with a flat plate drive system. This type of system uses an open worm gear, which can cause grease to squeeze out over time, leading to a lack of lubrication and resulting in noise from chatter and vibration. To fix this issue, you will need to re-grease the open worm gear and realign the shaft collars and belt pulleys.

Another possible cause of noise in boat lifts is air in the system, which can create a squealing noise from the pump. To correct this, simply raise and lower the platform a few times without any load to release the trapped air.

It is also important to inspect the gears and belts of your boat lift monthly. Noisy operation may be due to un-greased gears or loose or fraying belts. Keeping these components well-maintained and lubricated will help to ensure smooth and quiet operation.

If your boat lift continues to make noise despite your best efforts, it may be time to consult a professional for further assistance. They can help diagnose and address any underlying issues that may be causing the noise.

Dealing with electrical wiring issues

Electrical wiring problems with your boat lift can be complex and challenging to troubleshoot. These issues can range from malfunctioning motors to faulty controls, and sometimes, increasing the voltage to the pump may be the solution. However, if your boat lift is rising too high, it could indicate a problem with the circuit controls. Corrosion is a common issue with electrical wiring, and it's essential to address it promptly to prevent further damage.

To repair electrical wiring issues, start by consulting your boat lift dealer, who can help assess the problem. Depending on the severity of the issue, they may recommend contacting a professional electrician to make the necessary repairs safely. It is important to take safety precautions when working with electrical systems to avoid any accidents or injuries.

Some common electrical faults include overheating components, faulty wiring, and corroded circuit contacts. These issues can cause the lift to raise the boat too high or function erratically. In some cases, faulty remote controls that need rewiring may make it challenging to raise or lower the boat. Therefore, it is crucial to inspect the system regularly and ensure proper use and preventive maintenance.

Additionally, it is essential to consider the power source for your boat lift. Some lifts may be hardwired into your electrical system, while others may use a plug-in power source. Ensure that the power source is adequate for the lift's requirements and that all connections are secure and free of corrosion.

Finally, remember that electrical wiring issues can be dangerous if not handled correctly. If you are unsure about any aspect of the repair process, it is always best to consult a qualified technician or electrician to ensure the work is done safely and effectively.

Removing rust from cables

Boat lifts are susceptible to rust, especially in saltwater environments. Rust can quickly accumulate on cables, which are typically made of galvanized steel or stainless steel, and this can lead to faulty drum winding, overloading, misalignment, and inadequate tension. It is important to address any signs of rust or fraying on boat lift cables as they are crucial for lifting the rack assembly and bearing the weight of the watercraft.

Clean the cables:

Use a degreaser or soapy water to clean the affected areas on the cables. Ensure that you dry the cables thoroughly after cleaning.

Apply a rust remover:

Use a quality rust and stain remover, such as RustFree, which is a phosphoric acid-based cleaner. Apply the product to the affected areas and let it penetrate for 30 to 60 seconds, depending on how severe the rust is.

Scrub the cables:

Use a Scotch Brite pad or a similar abrasive pad to scrub the cables until all the rust is removed. Be careful not to damage the cables during this process.

Neutralize and dry:

After removing the rust, neutralize the acidic residue of the rust remover by wiping the cables with a cloth dampened with soapy water. Ensure that you dry the cables thoroughly afterward to prevent new rust from forming.

Apply a rust protectant:

To prevent rust from returning, apply a rust and corrosion protectant, such as Boeshield T-9, to all metal parts, including the cables, railing, posts, and tensioning components. This will help protect against corrosion and ensure the longevity of your boat lift.

Repeat the process of cleaning, treating, and protecting the cables every 6 to 12 months, or more frequently if your boat lift is in a coastal or high-humidity environment. Additionally, consider applying a penetrating oil to your cables to reduce abrasive wear and protect against corrosion.

Replacing broken boat lift cables

Boat lift cables are crucial as they bear the entire weight of your boat. They are prone to rust and wear out over time, so they need to be replaced periodically. Here is a step-by-step guide on replacing broken boat lift cables:

Step 1: Inspection

Before replacing your boat lift cables, it is important to inspect them for any signs of damage. Look for rust spots, kinks, broken strands, and other abnormalities. Pay close attention to the vertical length of the cable, especially near the winch, as this is a common area for fraying. Always wear leather gloves when handling the cable to protect your hands.

Step 2: Lower the Lifting Platform

When replacing the cables, it is recommended to have the lifting platform or rack in the lowered position. This makes it easier to access the cables and ensures that the main cable does not go slack.

Step 3: Remove Old Cables

Before installing the new cables, carefully remove the old ones. Loosen any clamps or fasteners that are holding the cables in place. If the cables are broken, you may need to cut them to remove them safely.

Step 4: Prepare New Cables

Measure the length of the new cables to match the old ones. Cut them to size if necessary. Apply a penetrating oil to the cables to reduce internal friction and help preserve them. Do not use grease, as it can trap moisture.

Step 5: Install New Cables

Follow the manufacturer's instructions for installing the new cables. Make sure they are properly placed on their winders and attached to the cradle. You may need to use ratchet straps or web slings to hold the lift in place while installing the new cables.

Step 6: Test the Lift

Once the new cables are installed, test the lift to ensure it is functioning properly. Raise and lower the platform without any load to check that the cables are securely in place and there is no slack.

Step 7: Maintenance

To prolong the life of your new cables, proper maintenance is key. Clean them regularly and lubricate grease fittings according to the manufacturer's instructions. Inspect the cables periodically for any signs of wear or damage, and replace them as needed.
