The OptiMax JP is a derivative of the 3.0L OptiMax, and shares 95% of the same components. Because of this fact, no special training beyond OptiMax certification is required to work on and maintain OptiMax JP.

Custom built by Mercury Racing, the OptiMax JP is truly the toughest low emissions outboard available. It runs smoke free, and offers up to 40% better fuel efficiency than its gas derivative, on JP5, JP8, and Kerosene Jet A fuel. OptiMax JP is certified under the EPA emissions standards.

The OptiMax JP is available on GSA contract, is in stock, ready for delivery. It was created in response to a recent directive by the Department of Defense to cease the transportation of gasoline on ships or aircraft by 2010 and the US Navy's single fuel forward initiative.

The advanced powerhead features high performance cylinder liners featuring race-derived transfer and exhaust ports with hand-ground boost ports for increased power and overall performance. Custom pistons and o-ring cylinder heads, with special combustion chambers, were designed by Mercury Racing for a hand-in-glove fit, providing maximum horsepower and optimal running quality.

High performance rubber coated reed blocks cushion the impact of the five-petal, single stage carbon fiber reeds, greatly enhancing reed life without sacrificing performance. Unlike other Direct Fuel Injection (DFI) systems, OptiMax uses an exclusive 2-stage process. A burst of air (at 95 psi) shoots through the fuel, breaking it into a fine mist. This fine mist creates more surface area for combustion and stays suspended in the cylinder longer, resulting in a more consistent and complete burn.

The OptiMax JP comes equipped with the Mercury PCM 03 microprocessor and state-of-the-art SmartCraft Control Area Network (CAN) System.

The PCM 03 processor provides the ability to optimize fuel, spark timing, and knock control for each cylinder, enhancing engine running quality and performance. The PCM 03 processor also operates an electronic multipoint lubrication system. This reliable system delivers precise amounts of oil where and when it is needed. It also recognizes and allows the use of JP5, JP8, and Kerosene Jet A fuel. In extreme emergencies, the OptiMax JP will run on gasoline or even diesel fuel for a short time period.

The SmartCraft CAN System, a network of sensors and actuators, proactively monitors and controls multiple engine functions. It also enables the PCM 03 microprocessor to provide real-time engine function data to accessory SmartCraft gauges including speed, RPM, engine trim angle, fuel consumption and range, and much more.

Models are available with 25" (635mm) or 30" (762) production midsections outfitted with the Fleet Master gearcase with a 2:1 gear ratio. This gearcase features dual water pickups for additional water flow and cooling.

An assortment of Mercury and Mercury Racing® Lab Finished® propellers are available for virtually any application.
