Common units & reductions in stock:

Our standard marine transmissions feature helical gearing for quieter operation; hydraulic-operated and oil-cooled clutches for smooth, fast shifting; identical reduction ratios in forward and reverse, full power forward and reverse and minimal external plumbing.

Some models are available with down angle output to provide near-level engine installation, a feature of particular interest to boat builders for optimizing space within the vessel. For additional space savings, remote mounted V-drive and direct-mounted V-drive models are available

What Our Customers Say...

Tony Knewman

Twindisc 506 transmission rebuild

Hi James, just a quick note to say thanks again for repairing my gearbox.··I have had some bad experiences in the past from supposedly reputable companies in the marine industry, I thought I got very good service and overall great value from what was a pretty expensive exercise.

Terry Smith

Transmission upgrade

I would Like to thank you for the brilliant service I received from you with regards to purchasing a rebuilt Marine transmission for my boat.

The replacement hydraulic transmission to replace my old Manuel paragon transmission was of the exact length and dimensions needed to replace my old trans. Your expertise on sending me a replacement trans from the photos I sent is to be commended.

Rodney Deeble

ZF Transmission purchase

We sought your advice on the choice of a suitable engine to re-power our Townson 36.· You provided helpful guidance after inspecting the engine bay and previous installation.

Following the choice of engine it became evident a “drop-down” gearbox was required. With little time left before the Christmas break you identified a suitable gearbox, and on finding no stock was available in New Zealand, air-freighted the gearbox from Australia to Auckland, and efficiently fitted it to the motor, so allowing installation before the Christmas closure.· You have provided helpful after-sale advice.
