Common Boat Lift Problems and How to Fix Them

Published October 2, 2026

Boat lifts are built to handle regular use, but problems can still develop over time. Salt air, moisture, heavy loads, worn parts, and electrical issues can all affect how a lift performs.

Some problems can be traced to simple maintenance needs, while others require professional repair. Knowing the warning signs and a few basic troubleshooting steps can help you identify what may be wrong, determine what you can safely check, and know when it is time to call for service.

1. Boat Lift Won’t Raise or Lower

A lift that won’t move is often dealing with a power, control, motor, or gearbox issue. F&S Lift Pro services failed motors, drum switches, limit switches, auto-stop systems, and remote-control boxes such as GEM Remotes.

Troubleshooting Tips:

  • Check that the lift has power
  • Look for visible signs of damage to the control box or wiring
  • Check the motor for obvious damage or unusual sounds

  • Listen for humming, clicking, or grinding from the motor or gearbox

Avoid opening electrical components or attempting wiring repairs while the system is energized. If the motor hums but the lift doesn’t move, F&S recommends stopping operation and scheduling service.

2. The Lift Is Squeaking or Grinding

Grinding, squeaking, or other unusual noises often point to a lack of lubrication, worn bearings, misaligned components, or problems with the motor or gearbox.

Marine-grade grease and proper lubrication can help with routine wear, but loud or persistent noises should not be ignored.

Troubleshooting Tips:

  • Inspect visible components for wear or damage

  • Check for loose hardware

  • Lubricate moving parts according to manufacturer recommendations

  • Inspect pulleys, bearings, and cables

Persistent noises can be a sign that parts are wearing against each other and need professional attention.

3. The Boat Lift is Stalling Under Weight

If a lift operates normally when empty but slows or stalls with the boat on it, the system may be overloaded or struggling to lift the weight.

Troubleshooting Tips:

  • Check weight capacity and confirm fully loaded weight
  • Make sure the boat is positioned correctly on the lift

  • Check that the weight is balanced properly

  • Confirm the lift is receiving adequate power

Continuing to operate an overloaded lift can put additional strain on the cables, motor, gearbox, and other components.

4. Boat Lift Cables Are Frayed or Corroded

Boat lift cables are especially vulnerable to saltwater, moisture, and regular wear. Even stainless-steel cables can eventually corrode or weaken in coastal conditions.

Troubleshooting Tips:

  • Rinse with fresh water after saltwater exposure

  • Inspect for fraying, rust, kinks, or broken strands

  • Make sure cables are winding evenly on the drum

  • Apply anti-corrosion products

  • Replace corroded parts

Fraying, rust, broken strands, kinks, or cables that are not winding correctly are all signs that service may be needed. In the Wilmington saltwater climate, F&S generally recommends replacing stainless steel lift cables every two to four years, depending on use and maintenance.

5. The Boat Lift Is Raising Unevenly

If one side of the lift rises faster than the other, the problem may involve cable alignment, improper tension, or the condition of the pilings.

Troubleshooting Tips:

  • Check that the boat is positioned evenly on the lift

  • Inspect cables for uneven winding or visible damage

  • Look for noticeable differences in cable tension

  • Check for loose or damaged hardware

  • Use built-in leveling controls only according to the manufacturer’s instructions

Uneven lifting can also put additional strain on cables and other components. A professional inspection can help correct the alignment and identify any worn parts before more damage occurs.

Know When to Call for Boat Lift Repair

Basic troubleshooting can help identify an obvious problem, but a boat lift shouldn’t be operated if something doesn’t look or sound right.

Stop using the lift and schedule professional service if you notice badly frayed cables, loud grinding or screeching, uneven lifting, a motor that hums without moving the boat, or repeated problems after basic checks.
