On the Water, Reliability is Everything !



KG Mechanical are dedicated marine specialists, and a quality Yanmar Dealer. We maintain all types of marine vessels from the weekend fisherman to the professional, from the part time sailor to the full time world traveller.

Being authorised dealers for YANMAR, PERKINS and IVECO marine and industrial engines and ZF marine transmissions, allows access to genuine parts and technical information.

We provide quality service for all Yanmar diesel engines, pumps, and generators. We cover Papua New Guinea, Torres Strait, Solomon Islands, North Queensland and the Northern Territory.



Compact and powerful, clean and quiet, these are mid-range three and four-cylinder Yanmar diesels based on a completely redesigned engine block and new combustion system. The new 3JH5E and 4JH5E are fully compliant with EPA Tier 3 emissions regulations, so you can enjoy more displacement, power and torque, with low vibration, low noise and low emissions. Maintenance is easy and straightforward.
