Comprehensive Propulsion Shaft Inspection by YachtService.meWe perform a full range of diagnostics and precision measurements to assess every aspect of your yacht’s shaft performance.
1. Visual Inspection- Examine shaft surface, couplings, and bearings for cracks, wear, or corrosion.
- Identify pitting, scoring, or deformation along the shaft length.
2. Alignment Check- Use laser alignment tools to measure alignment between the engine, shaft, and propeller.
- Correct misalignments that can cause vibration and accelerated wear.
3. Bearing and Seal Examination- Inspect seals for leaks or hardening due to salt exposure.
- Test bearing condition and replace components showing excessive friction or play.
4. Shaft Straightness Testing- Conduct precision runout tests to detect bending or warping.
- Straighten or replace shafts that fail tolerance standards.
5. Corrosion and Surface Analysis- Identify galvanic corrosion, especially around the propeller end or couplings.
- Apply protective coatings or recommend replacement of compromised parts.
6. Coupling and Keyway Inspection- Check couplings, bolts, and keyways for wear or looseness.
- Retighten or replace to maintain secure power transmission.
7. Performance Testing- Run the propulsion system under load conditions.
- Monitor for abnormal noise, vibration, or temperature fluctuations.
Common Problems Solved by YachtService.me a. Excessive VibrationsCause: Misaligned or bent shaft, worn bearings, or imbalanced propeller.
Solution: Shaft realignment, bearing replacement, and dynamic balancing.
b. Leaking Shaft SealsCause: Worn or cracked seals allow water ingress or oil leakage.
Solution: Replace seals and verify proper fitment.
c. Corrosion and PittingCause: Galvanic activity or saltwater exposure.
Solution: Remove corrosion, apply protective coatings, or replace components.
d. Reduced Propulsion EfficiencyCause: Shaft misalignment or bearing wear reduces power transfer.
Solution: Precision alignment and component replacement.
e. Shaft Noise or KnockingCause: Loose couplings, bearing failure, or misalignment.
Solution: Tighten and align couplings, replace bearings.
f. Overheating BearingsCause: Poor lubrication or excessive friction.
Solution: Replace or re-lubricate bearings and inspect seals.
g. Shaft Bending or WarpingCause: Impact from debris or prolonged strain.
Solution: Straighten or replace shaft, verify engine alignment.
Pro Tips from YachtService.me Experts- Schedule Inspections Annually or Every 200 Hours: Prevent unseen wear from developing into major damage.
- Use Proper Anodes: Incorrect anode selection can accelerate galvanic corrosion on the shaft.
- Monitor Vibration and Noise Levels: Early detection of imbalance saves time and repair costs.
- Avoid Running in Shallow or Debris-Filled Waters: Propeller impact is a leading cause of shaft bending.
- Lubricate Bearings Regularly: Follow manufacturer intervals to maintain smooth operation.
