Shafts, Propellers & Running Gear Refit Laser Alignment, Dynamic Balancing & Stern Seals.
Vibration-free propulsion protects gearboxes, cuts fuel consumption, and delivers whisper-quiet cruising. PMT oversees running gear overhauls in drydock: computer-aided propeller pitch tuning, laser shaft alignment, cutlass bearing replacement, and mechanical face seal renewals.
Optical Shaft Alignment, Propeller Tuning (ISO 484/2), Cutlass Bearings & Seals
Backed by 39+ years at sea, PMT Yachts Pro delivers uncompromising quality, transparent reporting, and independent owner advocacy.
Operational Rigor: Dynamic Propeller Pitch Tuning & Balancing
Scanning propeller blades with digital Pitchometers, tuning pitch across all blades, and dynamic balancing to ISO 484/2 Class S standards.
Tailored For Maritime Decision-Makers
Whether you operate privately, manage charter assets, or oversee institutional superyachts.
Yacht Owners Experiencing Vibration
Eliminating annoying hull vibration, rumbling running gear, and premature shaft seal leaks.
Drydock Survey Requirements
Mandatory 5-year classification shaft pulling, crack testing, and bearing clearance inspections.
Propeller Damage Recovery
Straightening bent blades, re-pitching for optimal engine RPM, and edge dressing.
What PMT Handles
Specific, hands-on operational deliverables executed with captain-grade oversight.
Dynamic Propeller Pitch Tuning & Balancing
Scanning propeller blades with digital Pitchometers, tuning pitch across all blades, and dynamic balancing to ISO 484/2 Class S standards.
Laser Driveline & Strut Optical Alignment
Using laser alignment optics to ensure the engine output flange, gearbox, shaft log, P-bracket struts, and rudder bearings form a straight line.
Shaft Straightening & Dye-Penetrant Crack Testing
Checking pulled shafts in heavy-duty lathe beds for runout, cold hydraulic pressing, and NDT testing on taper keys and threads.
Cutlass Bearing Replacement
Extracting worn water-lubricated rubber or composite cutlass bearings and pressing in new custom-machined nitrile rubber bearings.
Dripless Shaft Seal & Stern Tube Overhauls
Servicing Tides Marine SureSeal, Deep Sea Seals, or mechanical face seals, including spare seal carrier installation.
Propspeed Foul-Release Coating Application
Applying certified Propspeed non-toxic foul release coatings to propellers, shafts, rudders, and trim tabs to prevent growth.
Shafts, Propellers & Running Gear Refit Laser Alignment, Dynamic Balancing & Stern Seals. In Action
Every journey, technical refit, and maritime operation executed with uncompromising aesthetic and engineering standards.
Operational Precision: Laser Driveline & Strut Optical Alignment
Using laser alignment optics to ensure the engine output flange, gearbox, shaft log, P-bracket struts, and rudder bearings form a straight line.
Structured Execution Process
From preliminary technical audit to final sea trials and documented sign-off. Every phase gated by uncompromising maritime standards.
Pre-Haul Vibration Baseline
Perform sea-trial vibration spectrum analysis to pinpoint frequencies (1x shaft speed vs. blade pass).
Drydock Disassembly
Safely uncouple shafts, press off propellers, and measure existing bearing clearances.
Workshop Balancing & Trueing
True shafts in precision lathe and computer tune propeller pitch and dynamic balance.
Laser Optical Re-Assembly
Install new cutlass bearings and align the driveline with laser targets before coupling.
Sea-Trial Validation
Underway vibration measurement confirming silent, silky-smooth power delivery across all RPMs.
Turnkey Standard: Shaft Straightening & Dye-Penetrant Crack Testing
Checking pulled shafts in heavy-duty lathe beds for runout, cold hydraulic pressing, and NDT testing on taper keys and threads.

Vibration is a Symptom, Not a Normal Sound
A properly aligned yacht runs with library silence. We do not rest until every trace of running gear vibration is gone.
Fuel Economy Savings
Balanced props and true shafts can increase cruising speed by 1 to 2 knots while burning less diesel.
Long-Term Gearbox Protection
Eliminating shaft misalignment prevents expensive damage to transmission output bearings and seals.

Frequently Asked Questions
Running gear vibration is typically caused by a slightly bent propeller blade tip, uneven blade pitch distribution, bent shaft, worn cutlass bearings, or misalignment between the engine mounts and the shaft strut.
Request Dedicated Consultation
Please specify vessel length, shaft diameter, propeller blade count/material, symptoms, and target haul-out date.
