                                           Our Charges

What goes into our labour charge?


We carry out a wide range of repairs to all vessel systems. We recognise there are varying costs associated with various tasks undertaken.

Rather than absorbing these costs into a subsequently higher hourly labour rate, we list them as separate line items on our quotes and invoices. We feel this is a fairer way to pass on these costs to our customers with a variety of work requirements in a variety of marina locations.


Our Consumables / Environmental levy

This line charge on our invoices covers, but is not limited to rags, lubricant sprays, sealants, adhesives, tapes, Loctite, cleaning products, electrical items (crimp terminals, zip-ties). As it is extremely in-efficient to quantify these items, we charge them out as fairly as possible based on the works carried out. Some onsite jobs may include parking fees covered by the consumables charge.

We are also committed to disposing our hazardous waste as environmentally friendly as possible as required by the EPA, Australian law, (but most of all, our conscience!). This in turn incurs substantial costs.


Our Service Vehicle Surcharge

Mariner Engineering’s SVS is a 50 cent per K/M charge that covers some of the running costs of our specialised services vehicles. This rate is actually set lower than the VACC advised rate of 75 cents.

Many of our customers, looking to reduce costs, arrange to bring their vessels to a closer berth or our workshop if possible. This minimises travel costs associated with the job.


What we charge for freight

To stock standard service items for most marine engines we need to have these parts on hand, minimising delays and makes for a more efficient job for everyone.

If a job calls for parts from outside of our stock, we have a vast supplier base all over the world. The parts department endeavour to source parts as locally as possible. Ordering from our dealer brands of Yanmar and Volvo on a regular basis, twice a week on average.

If parts for a specific job can be added to these regular orders then freight cost are shared and reduced significantly.

If turnaround time is of most importance, we can place a special order and have parts sent by the quickest freight option. Higher costs for these services are then passed on to the customer.
