Marine Fuel Injector Cleaning - Unichip Marine.


Petrol Injector Cleaning.

Fed up replacing injectors?

 Boat injectors live a much harder life than their road going counterparts - the marine environment, stagnant / low quality fuel and a lack of annual fuel system maintenance all take their toll. 

 One of the most predominant reasons for injectors failing is Foreign Object Debris mixing with your fuel. Contaminants & debris can be transferred from fuel bowsers, small flakes of paint from the inside of jerry cans and even your own fuel tank corroding can all build over time. 

Your fuel filter will catch the majority of this debris however, smaller particles can pass through this filter. On rough seas with 50% fuel load, your fuel crashes around within your fueltank, breaking these particles up even more. This is the fundamental reason why injectors fail.  

If a job's worth doing...

 IMPORTANT: You may have experience with fuel treatments / additives that claim to clean your injectors. While they may do a reasonable job overall, they will not provide a deep clean to the intricate areas such as the injector filter (pictured, right). Additives may alleviate some of the problems, but will not resolve them all. Unichip Marines service provides your injectors the love they need!

Commonly Asked Questions

Why should I clean my boat injectors?

A boat's fuel injectors spray/inject fuel into the intake manifold /cylinders at a precise angle.  Harsh usage, environmental factors and poor fuel quality are all common reasons as to why your injectors need professionaly maintaining. Failure to implement will result in reduction in fuel efficiency, difficulty starting your engines, idling problems and engine misfires. Your injectors can have a massive impact on your overall boating health and experience

What can I expect from Unichip Marine's professional injector cleaning service?

 Firstly, your injectors will be flow tested. They will then be stripped & ultrasonically cleaned in our state of the art facility. Once this process has been completed, they will once again be flow tested to check on results before they are returned. Small mechanical parts such as filters, o-rings, and pintal caps will be replaced if faulty / damaged. This is complimentary to the service we provide. 


How often should I clean my injectors? 

This depends on multiple factors however, a general rule is that you should clean your injectors at around every 300 engine run-time hours, or every 3 - 4 years. The overall integrity of your engine components, fuelling quality & your overall engine upkeep will all be contributing factors. 

How much better will my boat's performance be once they're clean? 

We can't put an exact percentage on how much power has been lost due to clogged injectors. You will however, see an increase in fuel economy and an increase in power now your engine receives the fuel it needs. This will also deliver a much smoother engine idle speed.  

Can't I just clean them myself?

We would not recommend this course of action. You can of course use carb cleaner + compressed air on your injectors, and you may experience some associated benefits however, only a professional clean will result in true results.

As a side note, self cleaning could lead to major issues in the future. If any debris is not completely removed, it can cause injectors to leak and can also cause fuel to wash oil away from your cylinder walls. This in turn, will cause friction, potentially resulting in engine meltdown. 

Trying to cut costsin the short term can cost considerably more in the long run. Avoid this today and enquire about our marine specialised petrol injector cleaning service today

Injector Cleaning Tips.

Buying a new set of quality injectors will increase power output due to their lack of physical defects. Lower quality injectors can leak oil from the solenoids, leaking horsepower! Always complete your research, read consumer reviews and be prepared to pay a premium when making mechanical decisions to your vessel.

Ensuring your boat has a high grade fuel filter / water separator system will improve injector longevity. This will minimise the risk of contaminants reaching your injectors, ensuring that you will need less injector maintenance. 

Using fresh, high quality fuel will minimise the risk of clogging injectors. Marine fuels are notoriously low quality than road going counterparts. Stagnant fuel increases the risk of contamination and lowers the overall fuel quality.
