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.

Primary and secondary fuel filters
Air filters
Valve adjustments
Gearbox oils and filters
Impelles

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
