We come to you
Mobile Service & Sea Trials
On-water testing and dockside repairs across greater Sydney. We come to the vessel, by road or by our own work boat.

Not every vessel can get to a marina. If the boat’s on a mooring and it’s broken down, we can get to it without you having to move it anywhere at a cost.
We work fully mobile, by road and by our own work boat, turning up geared up with the tooling and parts on board so we can work efficiently and get you sorted on the spot.
“If the owner has their vessel on a mooring and it’s broken down, we can get to it without the owner needing to move it anywhere at a cost.”
What’s involved
Fully mobile
By road and by work boat, right across greater Sydney, marina, mooring, or mid-passage.
Sea trials
On-water testing under real load, the only way to properly prove a repair, a repower or a boat you’re about to buy.
Dockside repairs
The everyday breakdowns and fixes handled where the boat sits, not weeks away in a yard.
No tow, no yard
No tow fees, no hauling out unless the job genuinely needs it. We get to the vessel.
Why Sydney Diesel Marine
Sydney Harbour, Middle Harbour, Pittwater, the Hawkesbury, Central Coast, Sutherland, and the South and North Coast of NSW, if the vessel can’t come to us, we get to the vessel.
Engines we service
Phil’s tips
Straight from the workshop
Tether the key to the sea cock
If you close the sea cock for the engine every time you leave the vessel, leave the engine key tethered to the sea cock handle. You physically cannot start the engine without opening the water first.
Keep the bilge clean
For closed bilges under the engine, keep the area clean. A clean bilge shows you immediately if anything is leaking, whether engine oil, diesel, coolant or seawater, before it becomes a breakdown.
