Smooth Power. No Vibration. No Surprises.
Your driveline is the critical link between your engine and the water — and when something’s off, you’ll feel it. Whether it's a vibration at cruising speed, a clunk in gear, or uneven performance, problems in the shaft line can quietly impact efficiency, safety, and long-term reliability.
At AB Marine, we provide precision driveline and shaft services for Auckland boaties who want their vessels running at peak performance. From subtle vibrations to serious shaft damage, we’ve got the tools and experience to get it sorted.
Our Driveline Services Include:
-
These wear items are critical to shaft support and watertightness — we inspect, replace and test as needed.
-
Bent, scored or corroded shafts can be machined or replaced to prevent drivetrain issues.
-
A correctly balanced and pitched prop not only improves speed and economy — it also protects your gearbox from excessive load and vibration. We work with trusted industry partners to carry out this specialised work.
-
We install and maintain premium mechanical seals that keep your bilge dry and shaft protected.
