Home' Ausmarine : August 2009 Contents When professional fisherman Paul
Sullivan decided to move up from his
trusty aluminium trailer boat to a
genuine sea-going commercial fishing
boat, he factored in an engine re-power
from the outset.
Operating out of Fisherman's Wharf on
Sydney Harbour, Paul Sullivan describes
himself as a commercial fish trapper. His
fishing grounds are within 10 nautical miles
of the coast and stretch from Cronulla in
the south to Broken Bay up north. Each trip
runs to about nine or ten hours at sea.
Initially Paul considered purchasing a
new boat, but the $600,000 price tag was
off-putting. Then he came across an
ex-West Australian cray boat, operating
out of Ulladulla. The 1981 'Randell 47'
was priced right, and with the
modifications required, plus a fresh
engine, the boat would be on the water
and ready for work at roughly half the
price of a new boat of the same size.
"In buying the Randall, I factored in a
re-power from the outset," Paul said. "The
engine was original, but it was old
technology and would have been noisy,
thirsty and expensive to run, not to mention
the oil leaks. The principal cost in
commercial fishing is fuel, so my plan was to
spend a bit up front to save a heap over the
Paul Sullivan researched his engine
alternatives and quickly learnt that Yanmar
was "THE" brand of choice amongst
"Other fishermen in the industry that I
know kept raving about Yanmar," Paul
said. "People kept referring to the
incredible fuel savings associated with
Yanmar, their quiet operation and
uncomplicated maintenance requirements.
I settled on the 6HYM-ETE model."
Once acquired, the Randall, 'Rachael E',
was taken down to Craig Hurst at Bermagui
(who is an authorised Yanmar Dealer) for
the re-power and associated hull work to
Craig has carved an enviable
reputation along the East Coast as a
Yanmar re-power specialist. His approach
to the project certainly won Paul as an
"Craig decided to completely strip out
the engine room and begin the re-power
with an empty room. The installation is an
absolute work of art -- it is spotlessly clean,
neat and simple."
Paul also had a MASE 6.5kVA genset
fitted in the engine room. This was needed
to power the big floodlights and deck lights
on board which are mainly used at the start
of the day when leaving port in the early
hours of the morning. The cabin also has a
decent fridge and microwave oven, so 240
volts was deemed essential.
"I chose MASE simply because it was
powered by a Yanmar diesel engine and has
the same warranty as the main engine,"
Yanmar's 6HYM-ETE model engine is a
true blue work boat quality engine and
includes Yanmar's latest combustion
chamber design named ASSIGN, a system
originally pioneered by Yanmar on their
large bore, low speed propulsion engines.
This technology combined with Yanmar's
own mechanical fuel system has enabled a
fuel consumption specification of
201gr/kW/hour at 100 percent load from the
heavy duty 368kW model, a result which is
the envy of many other brands and is giving
owners something to smile about in the
current times of high fuel prices. The 6HYM-
ETE offers an emission compliant IMO
certified product with full classification to
BV/ABS/LR/RINA and NK if required.
This is a six-in-line cylinder block that
displaces 13.733 litres. The induction
system features a 24-valve cylinder head
design with twin turbo chargers and can be
specified with four power ratings between
303kW at 1,850rpm to 515kW at 2,200rpm,
depending on the application and duty
cycle proposed. All up weight without a
gearbox is 1,385kg.
On the water, this translates to
performance and fuel economy that
delights Paul Sullivan. Working locally up
and down the New South Wales coast, the
'Rachael E' operates most efficiently at 12
knots with the Yanmar spinning over at
1,550rpm. Fuel consumption at this speed
is 25 litres per hour. With the fuel tanks
holding 1,800 litres of fuel, this gives
Rachael E 72 hours of endurance.
"The original engine in 'Rachael E' used
30 litres per hour at nine knots. It was very
thirsty and noisy."
"I couldn't be happier with my new
Yanmar engine," Paul Sullivan said. "Now
I'm operating 30 percent faster and using
"The re-power has delivered an excellent
outcome -- it has been a lot cheaper than
buying a new boat, I'm enjoying wonderful
fuel economy and reliability with not an oil
leak to be seen."
