Premium Fuel Injector Cleaning, Injector Flow Testing, & Ultrasonic Fuel Rail Cleaning
The Mercury Optimax uses a specialized injection system where fuel and air injectors work in precise sync, delivering a timed fuel-air mixture for maximum power. Performance can be affected by high-ethanol fuel or debris from air pump failures.
Our Mercury Optimax Air Fuel Injector Service uses custom-machined cups we designed and has CNC’s by our machine shop partners for the Carbon Zapp test bench and our proprietary POWERFLUSH machine to clean and test the air side of the injector stack. Premium service includes seal installation with our proprietary tool—at a cost lower than most shops charge for cleaning alone. Details are on our Port Injector Cleaning and Flow Testing page.
Our Optimax injector and Air injector service builds on the Port Injector service detailed on the Port Injector page. Some shops advertise Mercury Optimax air injector cleaning for $20, but this typically excludes O-rings and seals, which are extra—OEM Seal Kit #26-804875 alone costs $22.
To cut costs, many shops use aftermarket combustion seals, but most are inaccurate, they all come from the same supplier base regardless of who you buy them from. They were either too thin or too large or both. After discarding thousands of these, we now manufacture the proper precision-fit Optimax Air combustion seals ourselves.
To fix the quality gap in the market, we now produce our own proprietary Air Injector combustion seals and a precision billet aluminum re-sizing tool ensuring exact OEM-level fit and performance.
By making these components in-house, we can provide full Mercury Optimax cleaning and testing at a price lower than most shops charge for cleaning alone—no more worrying about short, bulging, inadequate seals.
As part of our standard Optimax Air service we always include:
We’ve developed premium Optimax AIR Injector combustion seals that match the OEM seals in full height and thickness. While many suppliers use incorrectly sized, lower-cost substitutes; or charge a premium for OEM parts. We manufacture fully accurate replacements seals ourselves, passing the savings directly to our customers.
We developed a specialized seal compression tool specifically for this injector. The commonly used nylon tool tends to pinch the seal at one end, causing a bulge and installation issues.
Our custom billet compression tool provides a perfectly uniform compression sleeve with precise, optimized dimensions.
OEM O-rings are often overpriced, and many aftermarket kits include incorrectly sized seals. After testing several unsatisfactory kits, we partnered with an O-ring manufacturer to produce our own precision-fit Viton O-rings; and we pass those savings directly to our customers.
