Mariner Engineering


Mariner Engineering is an authorised agent for the widely acclaimed and respected range of "Yanmar" diesel engines.
Yanmar engines come in an outstanding range.
We specialise in service, maintance and rebuilds of diesels between 10 and 800HP, and outboard motors between 2 and 150HP.

Apart from Yanmar, for whom we are an authorised service agent, we service and carry consumable parts for Volvo, Bukh, Sole, Perkins, Kubota, Nanni and Cummins.

We service and overhaul transmission such as Twin Disc, for whom we are an authorised dealer, ZF, Borg Warner, PRM and New Age / Coventry.

In our machine shop, we can manufacture propellor shafts, and shaft and rudder bearings to order. Many other types of bushings can be machined, brackets can be welded and threads removed and re-tapped or helicolied.

In addition to our main service centre, located in Williamstown, we operate four mobile service vehicles. These are frequently in the marinas of Williamstown, Pier 35, Docklands, St. Kilda, Brighton and Sandringham.
