Boat servicing in Fremantle spans everything from an outboard’s routine 100-hour check to the annual haul-out of a 90 ft motoryacht, and the standard of the work varies as widely as the vessels do. Motoryachts Australasia (MYA) runs its after-sales operation from the North Fremantle marina in the Rous Head Harbour precinct as an authorised Mercury Marine dealer, holding factory authorisation for service, maintenance and warranty work. Behind the workshop sits more than 80 years of combined marine experience, along with the obligations that come with representing Sunseeker, Saxdor and Sealegs in Western Australia.
If you are searching for the best boat servicing in Fremantle, the useful move is to stop reading adjectives and start checking criteria: factory authorisation, genuine parts, qualified trades in one place, and lifting capacity that matches your vessel. This article sets out how MYA answers each, what a tailored maintenance programme involves, and why factory-standard servicing keeps paying off long after the invoice is filed, right through to the day the boat is sold.
An authorised Mercury dealer, with the paperwork to match
Mercury Marine authorisation is not a logo on the shed. It means MYA’s Mercury-specialist technicians hold factory authorisation to carry out service, maintenance and warranty work, and that warranty repairs are completed to factory standard using genuine parts.
The distinction matters most on the day something fails. Warranty work performed outside authorised channels, or with non-genuine components, gives a manufacturer room to question a claim. Keeping the vessel with an authorised dealer keeps the record clean: genuine parts, factory procedures, and documentation the manufacturer recognises without argument.
Specialisation is the other half of the equation. A technician who works on one engine family week in, week out builds a diagnostic instinct a generalist cannot, which shortens the hunt for intermittent faults and trims the hours on the invoice. Genuine parts add a quieter benefit of their own: they are made to the tolerances the engine was designed around, which shows up as reliability over years rather than anything obvious on day one.
Warranty work itself follows the same standard. When a repair falls under warranty, MYA carries it out as authorised warranty repairs to factory standard, with genuine parts, so the fix is the one the factory intended rather than a workaround. For the owner, the process runs through one local dealership instead of a chain of intermediaries.
The complete scope of the workshop is set out on our service page. The sections below cover the questions owners raise most often.
What boat servicing in Fremantle covers at MYA
A modern motoryacht is several trades in one hull: an engine room, an electrical installation, a plumbing network and a finished interior, all sharing the same salt-laden environment. Splitting that work across separate contractors means split accountability, which is why the offer here is deliberately broad. The core after-sales services are:
- Engine servicing by Mercury-specialist technicians
- Mechanical and electrical diagnosis and repair
- Authorised warranty repairs to factory standard, using genuine parts
- Marine plumbing
- Antifouling
- Interior and exterior detailing to concours standard
Electrical work deserves particular mention, because boats have quietly become electrical platforms. Navigation electronics, battery banks, charging systems and shore power all interact, and a fault in one system often shows up as a symptom in another. Having electrical and mechanical capability in the same operation means the diagnosis does not stop at a trade boundary.
Plumbing follows the same logic. Freshwater systems, heads, bilge pumps and seacocks are unglamorous right up until one of them fails, and a seacock inspected on a hardstand costs a great deal less than one discovered the hard way in a flooded engine bay.
Antifouling earns its place on the list too. Fouling drags down speed and pushes up fuel burn well before it is visible at the waterline, and a coating applied properly during a scheduled haul-out outlasts a rushed job by seasons. Detailing, meanwhile, is held to a concours standard, which is a specific claim rather than a flourish: the finish is prepared to be judged up close, with gelcoat, brightwork and interior surfaces treated as part of the vessel’s presentation rather than an afterthought once the mechanical work is signed off.
Lifting to 200 tonnes, connected to the office
Serious servicing starts with getting the boat out of the water, and this is where MYA’s address does real work. The MYA office is attached to SFM Marina, so lifts, sheds, hardstands and pens are connected to the office rather than scattered across the port. One conversation covers the lift, the work and the berth afterwards, with no relocations between yards partway through a job.
The SFM Marine recreational facility at Rous Head Harbour runs two lifters rated to 200 tonnes and takes vessels up to 10 metres of beam. In practice that covers everything from a 14 ft trailer boat to a 90 ft cruiser, including catamarans and tri-hulls, whose beam puts them beyond many travel lifts.
The range matters in both directions. Fremantle’s fleet is not all motoryachts, and the facility that hauls a 90 ft cruiser handles the trailer boat with the same trades and the same water treatment behind it. The servicing standard does not scale down with the length of the vessel.
The facility employs qualified mechanics, electricians, shipwrights and engineers, so structural, mechanical and electrical work can proceed side by side while the vessel is on the hardstand. Wash-down water runs through a closed-loop treatment plant rather than back into the harbour, and the facility operates 7am to 4pm daily. SFM also runs a second facility at the Australian Marine Complex in Henderson.
The haul-out process, hardstand options and pen arrangements are covered in detail in our guide to boat lifting and servicing in Fremantle.
Tailored maintenance programmes and 24/7 technical support
No two vessels age the same way. A flybridge cruiser that does forty hours a season needs different attention to a Saxdor that runs to Rottnest most weekends, and an amphibious Sealegs adds considerations of its own on top of the usual marine ones.
Perth conditions sharpen the point. Long summers of hard UV, salt spray and a working harbour environment are relentless on gelcoat, canvas, seals and electrics, and a schedule written for milder waters ages badly here. Maintenance planned around local conditions is not a luxury; it is how the boat stays reliable and presentable.
MYA builds tailored maintenance programmes around the individual vessel and how it is actually used. Engine servicing, antifouling, plumbing checks and detailing are timed to the boat’s real hours and exposure rather than to a generic calendar, so wear is caught on the hardstand instead of announcing itself offshore. The programme also removes the most common failure mode in boat maintenance, which is nobody being responsible for remembering.
Behind every programme sits a 24/7 technical support line. Faults rarely choose business hours, and an owner staring at a warning alarm at anchor on a Sunday evening can speak to the dealership rather than a search engine. The line exists for precisely the moments a manual cannot cover: an unfamiliar alarm, a system behaving oddly mid-passage, a decision about whether to press on or turn back.
There is continuity in the arrangement as well. MYA is the official Western Australian dealer for Sunseeker and Saxdor and, since July 2026, the appointed WA dealer for Sealegs amphibious craft. The business that sells these vessels is the same one that services them, which means the team quoting your work already knows the boat.
Service history is resale value
Every haul-out, oil change and warranty repair becomes part of the vessel’s file, and that file is one of the first things a buyer’s broker or surveyor asks to see. A documented history of authorised servicing with genuine parts answers questions before they are asked, and a vessel with a clean record is a noticeably easier sale.
MYA sits on both sides of that conversation. The same office that maintains vessels also runs a brokerage with around 30 listings at the time of writing, spanning roughly A$7,000 to A$995,000 and topped by a Sunseeker Manhattan 60 MKII. The brokers see daily what a thin service file does to a negotiation, and the workshop exists partly so that MYA-maintained vessels never arrive at market with one.
How the two operations reinforce each other is covered in our article on Perth yacht brokerage and servicing, and the current stock is on the pre-owned page.
The practical advice is short: keep the record complete from the first service onward. Every owner is a future seller eventually, and the discipline costs nothing beyond doing the servicing properly in the first place.

Frequently Asked Questions
Does Motoryachts Australasia service Mercury engines?
Yes. MYA runs its own Mercury service department, and its Mercury-specialist technicians service and maintain Mercury power to factory standard using genuine parts. Warranty work is covered on the Mercury engines supplied new with the boats MYA sells. The workshop operates from the North Fremantle marina in the Rous Head Harbour precinct, backed by more than 80 years of combined marine experience across the team.
How big a boat can be lifted for servicing at Rous Head?
The SFM Marine recreational facility attached to MYA's office runs two lifters rated to 200 tonnes and takes vessels up to 10 metres of beam. That covers everything from 14 ft trailer boats to 90 ft cruisers, including catamarans and tri-hulls. The facility operates 7am to 4pm daily and uses a closed-loop water treatment plant.
Does MYA offer after-hours technical support?
Yes. A 24/7 technical support line backs the servicing operation, so a fault at anchor on a weekend does not have to wait for business hours. For scheduled servicing, warranty work or a tailored maintenance programme, the office can be reached on +61 499 770 180, with viewings available seven days by appointment.
What is included in a tailored maintenance programme?
Each programme is built around the individual vessel and how it is used, drawing on MYA's full servicing range: engine servicing by Mercury-specialist technicians, mechanical and electrical work, marine plumbing, antifouling, and interior and exterior detailing to concours standard. Warranty repairs with genuine parts are handled as required, and work is documented so the vessel builds a complete service history.
Where is MYA's boat servicing facility located?
MYA operates from the North Fremantle marina in the Rous Head Harbour precinct. The office is attached to SFM Marina, so lifters, sheds, hardstands and pens are connected to the office rather than spread across the port. SFM also runs a facility at the Australian Marine Complex in Henderson.
