Precision Propeller Shaft Engineering

Propeller shafts are a critical component of any vessel, transmitting engine power to the propeller while withstanding torque, vibration, and water pressure. Lex Baddiley Marine Engineering combines technical expertise with modern machinery to ensure shafts are engineered and maintained to exacting standards. Precision alignment, inspection, and balancing are all performed to maximise efficiency, reduce wear, and extend the lifespan of your vessel’s propulsion system.

Computerised Propeller Sizing

Selecting the correct propeller size and pitch is essential for optimal performance. Using advanced computerised propeller sizing tools, our team analyses vessel specifications, engine output, and operating conditions to recommend the ideal propeller. This service improves fuel efficiency, reduces vibration, enhances speed, and ensures smoother handling for private and commercial vessels alike.

Prop Repitching & Balancing

Over time, propellers may require adjustments to maintain optimal performance. We provide professional propeller repitching and balancing, which corrects inefficiencies, minimises vibration, and extends the life of the propulsion system. Balanced and correctly pitched propellers reduce strain on the engine and drive system, contributing to quieter and more fuel-efficient operation.

Propspeed Application for Shaft & Propeller Protection

Marine environments are harsh on metal components. Our team applies Propspeed coatings to propellers, shafts, and rudder gear to prevent corrosion and marine growth. This protective layer ensures smoother operation, reduces maintenance requirements, and prolongs the life of critical propulsion components, making it an essential service for vessels operating in saltwater conditions.

Shaft, Rudder Gear & Bearing Maintenance

In addition to propeller services, our engineers inspect, service, and replace shafts, rudder gear, and bearings. Regular maintenance keeps the entire propulsion and steering system running safely and efficiently. By addressing wear and alignment issues early, vessel owners can avoid costly repairs, reduce downtime, and maintain smooth, reliable handling on the water.

In-Water & Hardstand Capabilities

Lex Baddiley Marine Engineering operates from Rivergate Marina & Shipyard in Murarrie, QLD, offering both in-water and haul-out services. The 15 m in-water berth allows for diagnostics, propeller checks, and minor adjustments without removing the vessel from the water. For more extensive work, the 75T and 300T travel lifts enable safe haul-outs of vessels of all sizes, including large yachts. This flexibility ensures efficient service with minimal disruption to the vessel owner.

Propeller Shaft FAQs

  • Why is propeller shaft alignment important?

    Proper alignment ensures smooth power transmission, reduces vibration, and prevents premature wear on shafts, bearings, and the engine.

  • How often should propellers be repitched or balanced?

    Frequency depends on vessel use, but regular inspections help maintain efficiency, fuel economy, and smooth operation.

  • What is the benefit of computerised propeller sizing?

    Computerised sizing ensures the propeller matches engine and hull characteristics, optimising performance, fuel efficiency, and vessel handling.

  • How does Propspeed protect propeller shafts?

    Propspeed coatings reduce corrosion and marine growth, lowering maintenance costs and improving the smoothness and efficiency of the propulsion system.

  • Can work be done in water or only on haul-out?

    Minor adjustments, inspections, and diagnostics can be performed in-water, while more extensive shaft and propeller work is done on the hardstand using travel lifts.

  • Do you service both private and commercial vessels?

    Yes. We provide propeller and shaft services for all vessel types, from private yachts to commercial craft, across Rivergate and Brisbane, QLD.
