Comments:
Originally built in Western Australia, this West coaster 72 left the factory powered by the 17.5
Lt cubic capacity Yanmar 6LAHM-STE3 complete with the Nigata MGN80 that is still going
strong today. It spent most of its life working as a Tuna Long liner out of WA before it was
based out of Mooloolaba in Queensland where it continued to work as a Tuna Long liner.
Eventually it was sold to the current owner in Tasmania, modified and put to work as an
Abalone Mother Ship. When the re-power was undertaken in July 2014, the original engine
had clocked up close to 48,700 hours without a single rebuild. Due to the 6AYM-WST having
a very similar horsepower rating as the original engine, the transmission was retained and the
front PTO arrangement all mounted up without modifications. Fuel consumption is 12 Lts/hr
better for the same cruise speed and the most noticeable improvement is the 6AY's improved
torque rise and acceleration.
