WM50 Diesel Engine
(Click to enlarge)

The WM50 diesel is professionally marinized in Australia. Our engineering upgrade is heavy duty, and only proven components are chosen. Standard features include ZF Hurth gearboxes, Johnson water pumps, Polyflex engine mounts, Bosch electrical gear and VDO instrumentation. All WM Diesel engines feature large capacity heat exchangers made from 'admiralty bronze' with heavy walled copra nickel tube, which is hand soldered (with 45% silver solder) for extra long life. 

The WM50 is based on the Kubota V2203-B and features the new E-TVCS, 3 vortex pre-combustion chamber design from Kubota. This offers improved efficiency with lower emissions.

All WM Diesels are covered by a full 12 months parts and labour warranty and the base Kubota engine has a 2 year world-wide warranty.
