The WM12
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 WM12 is based on the Kubota Z482 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. |
