Signs of a faulty fuel injector
Sea-Doo fuel injectors can be professionally cleaned by shipping them to a service provider. The process involves a comprehensive diagnostic and cleaning regimen, including flow and spray pattern testing.
- Increased Fuel Consumption: While this could be due to other factors, like spark plugs, it is worth considering fuel injectors as a potential cause.
- Reduced Performance: Dirty or leaking injectors will reduce the performance of your Sea-Doo's engine.
- Engine Surging or Bucking: This can be caused by reduced or poor fuel flow, leading to engine surges when one cylinder receives the appropriate amount of fuel while another does not.
- Knocking Noise: Although this could indicate a catastrophic issue, many times it is caused by poor fuel flow, which can be rectified by cleaning the injectors.
- Smoking Tailpipe: A tailpipe emitting smoke could be due to a rich or lean fuel mixture rather than burning oil.
- Poor Idling: A Sea-Doo with a rough idle could be caused by dirty injectors failing to deliver the right amount of fuel to the engine.
- Loss of Full RPMs: Performance issues, such as a loss of RPMs, may be attributed to dirty, clogged, or faulty fuel injectors.
- Hard to Start: Dirty injectors may not deliver enough fuel for normal starting, making it challenging to get your Sea-Doo running.
- Check Engine Light: The check engine light may illuminate due to incorrect fuel delivery, leading to error codes and warning lights.

Using fuel injector cleaner
If you're looking to clean your Sea-Doo fuel injectors, there are several options available to you. One option is to use a fuel injector cleaner, which can be added directly to your fuel tank. This is a convenient and effective way to clean your fuel injectors and improve your engine's performance.
There are several fuel injector cleaners on the market, such as Sea Foam IC5 Fuel Injector Cleaner, which is designed to be poured directly into your fuel tank. It is formulated to clean fuel injectors and restore injector spray patterns, leading to enhanced engine performance and power. One bottle treats up to 25 gallons, and it is recommended to add it when the tank is low to maximise its cleaning concentration. Regular use can help prevent issues like hard starts, rough idling, and engine hesitations.
Another option is to use a high concentration of Sea Foam Motor Treatment, which is also an effective fuel injector cleaner. This method involves adding a small amount of fuel (2-4 gallons) and a whole 16 oz can of the treatment to your tank. Then, you simply drive until the tank is almost empty, allowing the treatment to clean your fuel injectors. This method is ideal for treating large fuel tanks without having to fill the entire tank with the treatment.
Additionally, some people choose to manually clean their fuel injectors. This involves removing the injector rail and injectors, and then using a throttle body cleaner to spray out any contaminants. However, this method may not be as comprehensive as using a dedicated fuel injector cleaner or seeking professional cleaning services.
It is worth noting that some fuel companies add injector cleaners to their products. For example, Chevron uses "Techron", a detergent additive designed to clean injectors and reduce carbon deposit build-up. Using high-quality fuel from reputable companies can help keep your fuel injectors clean and maintain the performance of your Sea-Doo watercraft.

Manually cleaning fuel injectors
- Prepare the necessary tools and safety equipment. It is important to wear face and eye protection and have a fire extinguisher within easy reach.
- Disconnect the battery and locate the fuel injectors. Refer to your vehicle's manual for specific instructions on locating the fuel injectors.
- Disconnect the fuel pump or supply line. This will allow you to access the fuel injectors and prevent fuel from flowing during the cleaning process.
- Remove the fuel injectors. This step may vary depending on the vehicle, but it typically involves unscrewing bolts and disconnecting wiring.
- Clean the fuel injectors. Use a can of throttle body cleaner or a high-quality injector cleaning kit to spray and clean the injectors. Pay close attention to the inlet side, which has a cone-shaped screen to catch contaminants.
- Inspect and verify the cleanliness of the fuel injectors. Use a light source to check if there is any remaining debris or buildup.
- Reassemble the fuel injectors. Ensure that all components are properly connected and secured.
- Add a fuel injector cleaner to the fuel tank. This will help maintain the cleanliness of the fuel injectors and prevent future buildup.
It is important to note that the above steps provide a general guide, and the specific process may vary depending on the vehicle and the products used. Always refer to the manufacturer's instructions and take the necessary safety precautions when working with fuel injectors.
Additionally, some sources suggest using high-quality fuel and fuel additives to prevent the need for manual cleaning. For example, using top-tier gasoline can help mitigate injector clogging issues, and major fuel companies often add injector cleaner to their products.

Flow testing fuel injectors
To clean Sea-Doo fuel injectors, you must first identify whether they are dirty or clogged. Some signs of faulty fuel injectors include increased fuel consumption, reduced performance, engine surging or bucking, knocking noises, smoke from the tailpipe, poor idling, loss of RPMs, and difficulty starting the engine.
If you suspect your Sea-Doo fuel injectors require cleaning, you can either manually clean them or send them to a professional service for cleaning and flow testing.
- External Cleaning and Inspection: The injectors are first cleaned externally using a special detergent and visually inspected for any damage or issues.
- Resistance, Shorts, and Current Draw Testing: The injectors are then tested for resistance, shorts, and current draw. This includes ohm testing to verify the condition of the injector coil by measuring resistance across the terminals.
- Paint and Rust Removal: Any loose paint and rust are removed from metal injector bodies using a wire brush. Plastic injectors skip this step.
- Disassembly and Internal Cleaning: The injectors are disassembled, and components like filter baskets, O-rings, and pintle caps are removed. The injectors are then re-cleaned to eliminate any remaining particles or dirt.
- Ultrasonic Cleaning: The injectors are placed in an ultrasonic cleaning tank with special detergents. Ultrasonic waves agitate and dislodge internal and external buildup, pushing out dislodged dirt, carbon, gum, and varnish. This step typically lasts for a minimum of 30 minutes and may be repeated if the injectors fail subsequent tests.
- Leak Testing: The injectors are tested for leaks at the injector body and output nozzle.
- Static Flow Test: Injectors are flow tested for 15 seconds at a specific fuel pressure (43.5 psi or 3 BAR) while held full open (static).
- Dynamic (Pulsed) Flow Test: Injectors are tested for 30 seconds at different duty cycles and pulsed at varied pulse widths to simulate real-world conditions such as idling, acceleration, deceleration, low speed, and high speed.
- Flow Rate Testing: The volume of gas each injector flows in cc/min at specific fuel pressure is measured. Injectors in a set should ideally flow within 5% of each other for optimal engine performance.
- Lubrication and Sealing: After flow testing, the injectors are lubricated with a special lubricant and sealed in poly bags.
Please note that the specific steps and procedures may vary slightly depending on the service provider or the model of your Sea-Doo watercraft. Additionally, some services may include additional tests or inspections as part of their flow testing process.
