It’s been a week
From diagnosing a cracked turbo and waiting for new housing to fitting turbo and running up to find a further coolant leak
Pressure didn’t show a big drop in pressure so using boreoscope through egt port found coolant in manifold
From there we removed injectors to find a cracked cylinder head
Diagnosed, Stripped down, replaced head and several other part and reassembled and sea trialed in 3 days
Good Luck to Graham and the Caboom team as they run in the World Cup fishing comp this weekend
Tight lines

V12 heat exchanger stack removed for cleaning as part of the 5-year service schedule. This shows the reasoning behind not just doing a “flush” as others suggest. By doing a complete strip down, it allows for proper cleaning of both sides of the heat exchanger plate. It is not always the saltwater side that causes the problem, with salt/calcium buildup on one side and dirty coolant/staining on the other, heat does not transfer effectively. This is also the case for tube bundle style heat exchangers. Also, doing a full strip allows you to inspect for corrosion, bent/buckled/cracked plates, and replacement of old seals, etc.

This week saw us do a road trip to Sydney to carry out a service on mains, gearboxes and genset in this clean Sunseeker.
Loaded up the car with parts and oils on Wednesday and drove down to Rose Bay Marina
Oils and filters
Primary and secondary fuel filters
Air filters
Valve adjustments
Gearbox oils and filters
Impelles
Generator oils, filters, fuel filters, impeller, anode and drive belt

We often follow our customers boats to offer better continuity of service which also acts as a record of service

Been a couple of years since we’ve been down to Sydney for work and a lot more years since I’ve worked at Rose Bay Marina, so much has changed
