Shaun Tiedemann

Purchased a yacht in Sydney with a Yanmar 30HP which needed a bit of a health check and a little work done. Not being from Sydney (thank goodness) it could have been a little difficult but following recommendation from my local Tassie mechanic I had Ian and his team do the work. Great work. Needed it – as we brought her to Hobart without a sniff of breeze across the strait and down the East Coast. 3 days of motoring and she went like a charm. Thanks guys.

As a transient boater with Yanmar engine problems I was directed to Hume for help. They were great. First they walked me through all the things I could check. Then quickly got spare filters into stock. When my self-debugging didn’t work Ian and Nick came out to Reboot. Their diagnosis showed that the problem was not in the engine nor transmission. They set me up with a diver to check the cutless bearing while standing by to arrange a tow and haul. It turned out the tow was not needed. Their bill was modest and more than fair.
