What are signs that my boat propeller needs repair?

Vibrations, reduced top speed, increased fuel use, or uneven engine RPMs often point to a damaged or unbalanced prop. We inspect, balance, and restore your prop to factory spec for smooth performance.

Can a damaged propeller affect my fuel efficiency and handling?

Absolutely. Even minor dings or bends reduce efficiency and put strain on the drivetrain. We restore blade shape and balance to improve fuel economy, acceleration, and steering response.

Do you repair stainless steel and aluminum boat props?

Yes – we repair both aluminum and stainless steel props. Our process includes blade reshaping, welding (if needed), dynamic balancing, and polishing for optimal performance and durability.

How much does it cost to repair a damaged propeller?

Most prop repairs cost $100–$250 depending on blade material and damage severity. Severe cracks or broken blades may require replacement – we’ll inspect and provide a free estimate.

How do I know if I need to replace the prop instead of repairing it?

If the hub is spun, blades are severely cracked, or the prop is heavily distorted, replacement is usually the best option. We’ll advise honestly and help you pick the right pitch and diameter.

Do you offer propeller balancing to reduce vibration?

Yes – we use dynamic balancing to eliminate vibrations that can damage your gearbox and reduce ride comfort. A balanced prop protects your drivetrain and improves fuel efficiency.

Can you remove and reinstall the prop at the marina?

Definitely. We offer dockside propeller removal, repair pickup, and reinstallation. Whether you're in a slip or on a trailer, we handle the whole process so you can get back on the water fast.

Why would I need my propeller pulled off the shaft?

Propeller removal is necessary for inspections, shaft seal work, cutlass bearing replacement, or propeller repairs. Proper pulling prevents shaft damage and ensures the prop can be reinstalled safely and correctly.

What is propeller re-hubbing and when is it needed?

Re-hubbing replaces the inner rubber hub inside the propeller. It’s needed when the hub slips, causing loss of power, vibration, or poor acceleration even though the engine RPM increases normally.

What are signs of a spun or failing prop hub?

Common signs include sudden loss of thrust, inconsistent speed, high RPM with little movement, or vibration. A hub inspection confirms whether re-hubbing is required.

Can propeller removal damage the shaft or seals?

If done incorrectly, yes. We use proper marine pullers and techniques to safely remove the propeller without damaging the shaft, keyway, or shaft seals.

Does re-hubbing restore original performance?

Yes, re-hubbing restores proper power transfer from the engine to the propeller, improving acceleration, smoothness, and overall performance when the blades are still in good condition.

Do you inspect the prop shaft during removal?

Absolutely. We inspect the shaft, key, keyway, and hardware for wear or corrosion and recommend repairs if needed to prevent future issues.

Is propeller pulling and re-hubbing better than buying a new prop?

In many cases, yes. Re-hubbing is more cost-effective than replacing the entire propeller and provides reliable performance when the prop blades are still structurally sound.

What is a cutless bearing and what does it do?

A cutless bearing supports the propeller shaft and keeps it properly centered as it spins. It reduces vibration, minimizes wear on the shaft, and allows smooth power transfer from the engine to the propeller.

How do I know if my prop shaft alignment is off?

Common signs include excessive vibration, unusual noises, shaft seal leaks, or premature cutless bearing wear. Misalignment can also stress the transmission and engine mounts if left uncorrected.

What causes cutless bearings to wear out?

Normal wear, misalignment, sand or debris in the water, and bent prop shafts can all shorten bearing life. Boats operated frequently or in shallow water may require more frequent inspection and replacement.

What is included in prop shaft alignment service?

We inspect engine mounts, transmission alignment, shaft straightness, and coupling tolerances. The shaft is aligned to manufacturer specifications to ensure smooth rotation and minimize drivetrain stress.

Can running with a worn cutless bearing cause damage?

Yes. A worn bearing can cause shaft wobble, damage the strut, shaft seal, transmission, and even the gearbox. Replacing it early prevents costly drivetrain repairs.

How often should cutless bearings and shaft alignment be checked?

We recommend inspection every 12 months or during haul-out. Alignment should also be checked after engine mount replacement, propeller strikes, or transmission service.
