Servicing for performance

​
​Our goal with every outboard service, is to ensure that your boat and motor performs at its best for longer, so that you enjoy more quality time on the water. 

When we ​service your outboard we have a thorough checklist to ensure nothing's missed. We'll check the works. Everything from the winch handle right through to the boat bungs. Plus, we use only the best parts, oil and lubricants so you can be sure your engine is getting the very best.​ 

After service care

It's not just the boat service that's important, it's how you look after the boat in between services. At GT Marine, we help you look after your engine all the time, so you spend more time on the water and less time in the workshop. 

That's why we offer a range of tips and tools, covering everything from how to flush your boat properly to choosing a propeller and how to know if you need a permatrim. Plus, our exclusive to GT Marine 6-weekly maintenance checklist helps keep your engine running well and prevents expensive repairs. ​

Outboard motor service price

The cost of an outboard service depends on a lot of different factors, like the size and age of your engine and when it was last serviced. As a guide services range from $400 - $600 + GST for a 50 - 90HP and $700 - $900 + GST for a 100HP and over. 

Often outboard motors will come in for a service, but we'll soon discover issues that need to be repaired, commonly water pump issues. The best way to lower your service bill is to use your engine regularly, flush it properly and use the GT Marine Maintenance Checklist ever six weeks.  
Let the GT Marine team help you get more out of your boat.
