what is line boring?

Line boring is a specialised machining process used to ensure the stern tube and propulsion shaft on your vessel are perfectly aligned. Over time, or after impact, these areas can shift. Leading to misalignment, vibration, fuel inefficiency, and increased wear on gearboxes and engines. By machining the tubes to be completely straight and true, we restore the alignment and performance of your vessel’s propulsion system. The result? A smoother, quieter, and more efficient ride.

Proper line boring keeps your propulsion shafts perfectly aligned, preventing vibration, fuel loss, and mechanical wear. It’s essential for maintaining performance and longevity in any marine vessel.

We recommend having your propulsion system inspected every few years, especially if your vessel operates in rough conditions or shows signs of vibration or noise.

Yes. Our Cairns marine engineering workshop is equipped to perform line boring on commercial boats, government vessels, and large ships, including aluminium and steel hulls.

Common symptoms include increased vibration, uneven engine noise, excessive shaft wear, or poor fuel efficiency. If you notice any of these, it’s time to get your propulsion alignment checked.
