At Steve’s Mobile Boat Service, we understand that a reliable engine starts with a clean, efficient fuel system.

That’s why in 2025, we expanded our services to include mobile fuel injection diagnostics, testing, and repair, along with a state-of-the-art mobile diesel polishing service.

Whether you need to restore your injectors for peak performance or ensure your fuel is free from contamination, we bring the expertise and equipment directly to your vessel—wherever you are.

Fuel Injection Servicing, Diagnostics & Repair

Diesel engines are known for their durability, but fuel injection issues can quickly lead to power loss, poor fuel economy, rough running, and even complete engine failure. Our mobile fuel injection service ensures your injectors and fuel system components are operating at peak efficiency.


Our Fuel Injection Services Include:

✔️ Injector Testing & Calibration – Using specialised equipment, we check for correct spray patterns, pressure, and atomisation.
✔️ Injector Cleaning & Overhaul – Carbon buildup, varnish, and deposits are removed for optimal performance.
✔️ Fuel Pump Diagnostics & Repair – We inspect and repair mechanical and electronic fuel pumps to ensure proper delivery.
✔️ Leak Testing & Pressure Analysis – We diagnose leaks and pressure inconsistencies that could cause performance issues.


By servicing your fuel injectors and pumps regularly, you extend engine life, reduce fuel consumption, and improve throttle response—ensuring smooth sailing all season long.

Why Schedule Diesel Polishing?

✅ Pre-season Maintenance – Ensure your fuel is clean before the active boating season.

✅ Pre-Purchase Inspections – Verify fuel quality in a used boat before buying.

✅ After Long-Term Storage – Prevent injector clogging and engine stalling due to degraded fuel.

✅ For Long-Distance Voyages – Reduce the risk of fuel-related breakdowns far from shore.


Mobile Diesel Polishing Service – Clean Fuel, Reliable Engine

Fuel contamination is one of the leading causes of marine engine failure, especially in boats that sit idle for extended periods. Over time, diesel fuel can degrade, leading to water accumulation, microbial growth (diesel algae), and sediment buildup in your tank. Our mobile diesel polishing service effectively removes these contaminants, restoring your fuel system to peak condition.


How Our Diesel Polishing Works:

🔹 Advanced Filtration – Our system filters down to 2 microns, capturing dirt, sludge, and algae.

🔹 Water Separation – Removes 99% of water from your diesel, preventing injector and fuel pump damage.

🔹 Full Tank Circulation – Unlike traditional draining methods, our system cleans the fuel while it remains in the tank.

🔹 Contaminated Waste Disposal – We safely remove and dispose of the extracted sludge and water, keeping your boat environmentally compliant.


A clean fuel system means fewer headaches and more time enjoying the water!
