“I have known Stewie Butler for many years.  I first met him when he was swinging spanners and did some work for me. 

Over the years Stewie and I continued our association and in 1998, when he was running Lees Industries, he supplied a new 120hp naturally aspirated Iveco engine and did the engine room design for the refurbishment job I did on my old bay cruiser the Margaret C.



In late 2009 I started running Megumi, a 44ft Assegai marlin fishing boat, that had been in Fiji for a few years.

When I got the boat, she needed quite a bit of work done on the QSM 11 engines, turbos, cooling systems and gen set.


Stewie had taken over Sea Wasp some years earlier and I engaged his services to do the work to bring the boat to the excellent mechanical level we required for a boat that was going to do a lot of work.

The job was extensive, but the work was done to a very high standard and on schedule.

After the initial mechanical refurb, Stewie and his team continued their good work on Megumi, with scheduled maintenance and fixing any small problems we had, until I ceased to run the boat in January 2014.

In one instance, I had a warranty issue with Cummins over a heat exchanger and without hesitation, Stewie followed through with me and we were able to achieve the desired result.

I have recommended Stewie and his Sea Wasp team to many other boat owners and have never heard a bad word said about their work.

They show up on time, do a good job, charge fairly for their work and leave the engine room clean and tidy when they are finished.

You can’t ask for more than that.’’

“We have been dealing with Stewart and the crew for 11 years, we run 3 barges to and from Fraser Island on a daily basis and regularly require parts. Sea Wasp have always gone above and beyond to help us out in somewhat critical times. All the best in the future guys’’

Peter Fenton – Workshop Manager, Fraser Island Barges


“I have dealt with Sea Wasp for the last 16 years. In fact, they repowered my 40 foot O’Brian with a pair of 450 Iveco’s . Stewart and his team provide great service and technical back up. Drew his right hand man is always quick to help, in and out of normal business hours. The team is up to date on the latest technical advancements in diesel engines, which is very important with today common rail diesel engines. I wish the Sea Wasp team well in the future’’
