Honda AquaTrax F-12X

Description

At the forefront of the personal watercraft market, the AquaTrax F-12X represent the cutting edge of four-stroke performance.

Class-leading performance is provided by a water-cooled IHI turbocharger with water-cooled intercooler. The AquaTrax® F-12X turbocharger produces a maximum boost of 13 psi to generate 32 percent more power than a normally aspirated engine.

The turbine bearing is an enclosed, ceramic-ball design that withstands sustained high-rpm compressor operation while providing nearly vibration- and friction-free performance. Water-cooling of the turbocharger housing maintains optimum turbine operating efficiency, while the water-cooled intercooler assures a denser intake charge to provide maximum power and combustion efficiency.

An electronic control unit (ECU) monitors, boost pressure, engine speed, cylinder head temperature and an engine knock sensor to manage an electronic waste gate valve that controls turbocharger boost, protecting vital engine components and maintaining long engine life.

Features

AquaTrax F-12X Features:

Purpose-built marine-duty 1235cc liquid-cooled fuel-injected inline four-cylinder four-stroke engine delivers amazing power across a broad rpm range. The inherently efficient, low-emissions four-stroke design consumes less fuel than a comparable two-stroke engine and meets all current CARB and Environmental Protection Agency (EPA) emissions standards.
Engine power and pump characteristics are carefully matched for maximum performance without the use of power-robbing gear-reduction systems, moving the AquaTrax F-12X to planing speed more rapidly than a conventional two-stroke watercraft--ideal for one, two- or three-person cruising, sport riding, skiing and wake-boarding.

Engine/Drivetrain:

Lightweight, 1235cc liquid-cooled DOHC 16-valve dry-sump four-cylinder engine with one-piece upper-crankcase/cylinder block is engineered to withstand the rigors of marine duty.
Side-mounted cam chain and ultra-narrow cylinder-sleeve spacing reduce engine size and weight.
Crankshaft main bearings feature a micro-grooved bearing surface to improve oil retention and bearing durability as lateral loading occurs throughout a broad range of operating conditions.
DOHC-actuated valves use a simple, lightweight and direct cam-over-bucket design.
Four-valve cylinder head design with a narrow, 30 degree included valve angle creates a compact combustion chamber for optimum efficiency and power output at all rpm levels.
Silent-type cam chain reduces engine noise, while an automatic chain tensioner virtually eliminates maintenance.
Oil jets located on the crankcase main journal castings continually cool piston undersides, ensuring consistent operating temperatures and even better engine life under maximum power.
Air intake system features an intake port mounted centrally in the hull and a labyrinth airbox construction with paper air filter. Together they keep water out of the engine during normal operation and if the craft is accidentally overturned.
High-pressure programmed fuel injection (PGM-FI) delivers fuel at 43 psi to four injectors, each mounted in a 38mm throttle body. Fuel is delivered through four laser-drilled nozzle holes in each injector, producing a highly combustible air/fuel charge for maximum combustion efficiency and power.
PGM-FI setting result in increased cruising range and less fuel consumption.
The ECU provides two digital 3-D fuel injection maps for each cylinder, creating the ideal fuel mixture and spark advance settings. A sophisticated throttle sensor and advanced fuel injection mapping combine to produce smooth and linear throttle response, responding precisely to minor throttle adjustments.
A fast-idling system uses an electric stepping motor to maintain a stable idle speed when the engine is cold. An automatic fuel enriching system is integrated into the PGM-FI module, eliminating the need for a manual choke.
Powerful, compact oil-cooled alternator contributes to the engine’s lightweight design.
Oil pump is driven by the alternator, further contributing to the engine’s lightweight design.
Engine cooling system allows water from the jet pump to circulate through two separate circuits to cool the engine and exhaust manifold, ensuring consistent operating temperatures for each system.
Unique three-way coolant coupler and specially designed discharge outlet reduce engine coolant flow during idling and low-speed operation to prevent over-cooling, assuring smooth operation and low emissions. A one-way valve permits simplified coolant system flushing.
Dry-sump engine incorporates an oil reservoir mounted adjacent to the cylinder bank. The tank shape and location, together with a specially designed internal multi-baffle system, optimise engine lubrication under a wide variety of marine operating conditions.
A specially designed crankcase breather system featuring three breather chambers prevents oil from flowing out of the engine or clogging the breather system if the hull is accidentally overturned.
Water-cooled cast aluminum exhaust manifold reduces exhaust noise.
Exhaust is equipped with a backfire flame arrester.
Crankshaft output end is directly coupled to the jet pump drive via a rubber damper, providing shock-free, efficient power transfer while minimizing lateral crankshaft load forces.
Pump servicing features include easy-to-disassemble pump, driveshaft, and driven coupling, and an easily accessible driveshaft bearing grease fitting.

Hull:

Unique AquaTrax hull design provides excellent overall stability and exceptional low- and high-speed turning performance without sacrificing the ability to perform low-speed maneuvers.
Dry-sump design allows the engine to be mounted low in the hull, resulting in a very low center of gravity that contributes to the AquaTrax’s exceptional handling performance.
Raised hull design aids in docking and provides excellent splash protection.
Sponson design further contributes to the AquaTrax’s low-speed maneuverability and high-speed stability.
Strong, lightweight fiberglass reinforced plastic (FRP) hull and deck are joined and permanently sealed at the gunwale, providing the AquaTrax with a distinctive and attractive profile.
The liner-type FRP inner hull increases hull rigidity more than 200 percent compared to a single-hull design.
AquaTrax hull is designed to be a stable platform for mounting from deep water and to be easily uprighted in case of accidental overturns
Footwell areas have an anti-slip surface to provide sure-footed comfort when mounting, operating and dismounting the AquaTrax.
Forward-located large-capacity, 62.8 litre polyethylene fuel tank is attached to the hull with rubber-cushioned hold-down straps. A two-way valve is provided to control internal tank pressure and prevent water incursion or fuel leakage if the hull is accidentally overturned.
Abundant storage is available in two sealed compartments, with a large, 87.4 litre front storage box located under the front hood and a smaller, 9.5 litre compartment located in front of the rider.

Additional Features:

Honda Ignition Control System (ICS) senses low oil-pressure and/or abnormally high coolant temperatures and acts to limit or shut off engine operation as necessary. If oil pressure drops below the optimum level, the ICS limits engine speed to 3000 rpm. Extremely low oil-pressure stops the engine. If high coolant temperature is detected, a warning light and audible alarm are activated. ICS also shuts off the engine after the hull is accidentally overturned.
AquaTrax’s selectable Limit Mode provides a lower top-speed setting, ideal for beginning riders, borrowers and rental users. The system displays “Limit Mode” on the multi-function display when activated, and can be reset with push-button controls.
Electronic keyless ignition system (ID mode) allows operator to select from 999 possible identification numbers to effectively deter unauthorized use
Waterproof instruments feature LCD digital displays for speed (kph), trip distance (kilometres), travel time (hours and minutes) clock and engine hourmeter; LCD bar graph display for engine speed and fuel level; flashing indicator light and audible alarm for fuel level, battery charge, coolant temperature, oil pressure and fuel injection
Self-diagnosing ECU cycles at start-up and operates continuously during operation to provide immediate troubleshooting and warning functions
Operational lanyard tethers the ignition button to the operator’s wrist or personal flotation device (PFD) and stops the engine if tether comes unplugged
The fully sealed fuel system is leak-free and vapor-free, eliminating the possibility of water contamination.
Anti-corrosion treatments for die cast aluminum components include Alodine / Alumite chromate surface plating with an additional Superlac top-coat for exterior components, and epoxy-resin-based primer applied to coolant-exposed parts before Alodine / Alumite treatment.
Extensive use of stainless steel, chrome plated and zinc plated stays and fasteners.
Waterproof electrical couplers and spark plug/coil caps
Rubber engine-mounts feature two-phase damping to simultaneously minimise engine vibration and engine shock when the AquaTrax is traversing rough water.
