Good afternoon all.
Easter is here.
Busy start to the year. We have just tis month caught up with repairs and servicing from end of last year.
We recently had an engine failure onboard Whyalla Pilot vessel Swither.
These engine have been looked after by us since new 18 years ago. They has 10,000 hrs on them
We had a possible injector failure after some poor fuel went through the system.
We sourced a pair of new engines ex Power Equipment in Melbourne.
We travelled to Whyalla and remove both Port and Starboard engine's.
We had to remove the rudders, propellers and pull the shafts to allow engine removal. These engines have a "V" drove transmission. The propeller shaft runs through the centre of the transmission.
We returned back to workshop. Swapped over all ancillary components. Serviced all pumps and mount. Repaired a transmission valve body change over. and service the transmission coolers.
Returned back to Whyalla and refitted two new engines, replaced all wiring harness and installed two new dash panels.
We sorted through some wiring repairs and electrical issues.
Had both motors running on the slip trolly and back into the water.
Quick sea trail, 27 knts at 3300 rpm.
e are about to go back and compete a 50 hr service and check over.
Two week trub around, start to finish.
Great work by all the guys and thank you Rohan.
Videos attached.

Good morning all.
Busy start to the year. March already.
Seasons are changing. Fog and dew on the ute in the morning.
Since Christmas we have been involved with an installation of a pair of Diesel outboards.
D-Torque 50 hp, for Marine and General Engineering at the north Arm.
Installation was ok , with a lot learnt. These are the first batch of these engines. Slight changes and modifications to vessel, steering systems and engine harnesses, needed to get the outboards up and running.
Time spent chasing parts and components that did not arrive with engine kits.
Propellers are custom made to suit these outboards, 9 x 14" ally three blade
Eventually barge was placed into water with a basic operational check completed.
engines are a 2 cylinder diesel with two crankshafts. each piston has two con rods, spinning each crank which are counted rotating from each other.
Quiet while running. Smooth operation.
Expected fuel burn around 3 or 4 Lt per hour while at cruise.
Surprisingly, the barge moved on its own and even was able to be steered.
2.5 knts in the river with a little bit of tide.
Barge is 50t
At sea trials there were two 2.5 t steel blocks on the deck. These were moved around the barge to simulate load.
Nice job, Will be easier next time.
Have a good one, be safe.

Hello all,
Last few days of this year. A couple of last minute jobs to get out the gate today.
Clean up the workshop, scrap and dump runs.
We have had a busy year. All the lads have worked hard on many projects.
We have completed several repower, refits and rebuilds.
General servicing still takes place, although most turn into major repairs.
Times have changed. maintenance is not what it used to be.
people are busy and most are unorganised.
All our customers are great to deal with, mostly happy to go ahead with repairs or replacement.
Hope you all have a good Christmas, see you next year.

We completed a repower on Katie.
27' Robert's.
Original engine was a Yanmar 3QM30.
Vessel came in for a vibration issue.
We found engine in poor condition and transmission had failed.
Discussed options with owner and wet down to road to install a new Yanmar 3JH40 common rail 3 cylinder engine.
Every corner we went to required work. Stern tube was rotten, Gland had failed. beds required work.
Wiring and fuel system up grade.
Ended up with a good and reliable little boat.
At sea trails we acheived 8 knots.
Cruise at 6 knots all day.
Great little river boat.
