Posted on by

The Honda AquaTrax R-12X reveals the style and feel of a motorcycle company and offers the quality of manufacturing of an automotive giant. MORE!!! More power, more speed, more action in turns, more adrenaline. That’s what a passionate ski jet rider asks from his ride and that’s what the Honda engineers had offered in the AquaTrax R-12X.

Engine


The AquaTrax R-12X is powered by a 1235cc liquid-cooled dry-sump inline four-cylinder with intercooled turbocharger. The AquaTrax® R-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.

The R-12X has a smaller hull then the other ski jets made by Honda. The especially design hull, the sharp chine and the sponsons along hull allows the boat to transition quickly into turns. Another innovation implemented by Honda in to the R-12X is the adjustable quick-trim system that can redirect the angle of the jet nozzle helping the driver to take sharp turns.

Test drive


The Honda R-12X has amazing agility, is very fast and stable, quiet and efficient, easy to maintain. The design of the hull makes the R-12X to cut the water like a scalpel and the adjustable quick-trim system makes this ski jet very stable and responsive in sharp turns. The stability and control of the R-12X is influence by the small hull and the emplacement of the engine. The only problem with this model is that it needs to be fueled with the best gas at gas stations (gas with 91 octanes) or else it won’t give the best performance, and makes a strange sound when the engine reaches 5000 rpm. Fueled whit the best gas it can reach a top speed of 75 mph.

Conclusion


One of the most intense, precise-handling watercraft, the Honda AquaTrax R-12X takes the spirit of the championship winning Honda sport bike to the water. Not for the faint hearted the R-12X provides all the adrenaline rush you need!

Engine/Drivetrain

Honda AquaTrax R-12X
  • Lightweight, liquid-cooled, turbocharged DOHC 16-valve 1235cc dry-sump four-cylinder engine features a one-piece upper-crankcase/cylinder block engineered to withstand the rigors of marine duty. The inherently efficient, low-emissions four-stroke design consumes less fuel than a comparable two-stroke engine and meets all current CARB and EPA emissions standards.
  • 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.
  • Idle screw adjustment conveniently located on front side of engine for ease of adjustment.
  • 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.
  • Honda Ignition Control System (ICS) protects the engine from abnormal operating conditions.
  • 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 holes in each injector, producing a highly combustible air/fuel charge for maximum combustion efficiency and power.
  • 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 and wastegate adjustments to maximize driveability, acceleration and drive pump performance.
  • A unique fast-idle 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.
  • Four waterproof, transistorized, direct-ignition coils integrate the spark plug cap and the high-tension lead to produce a high-voltage, long-duration spark, providing maximum performance at high engine-output levels.
  • Iridium-tip spark plugs produce maximum spark performance and minimal carbon buildup for consistent engine operation and long spark plug life.
  • 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.
  • Stainless-steel oil cooler for lower engine temperature and corrosion resistance.
  • 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, ensuring 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 multibaffle system, optimize engine lubrication under a wide variety of marine operating conditions.
  • A uniquely 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 contributes to total heat management and reduces exhaust noise.
  • 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.
  • Engine power and pump characteristics are carefully matched for maximum performance without the use of power-robbing gear-reduction systems.
  • Unique Honda-designed Solas 155mm jet pump with three-blade impeller is matched to four-stroke power characteristics. This proprietary Honda impeller design minimizes pump cavitation, resulting in quiet pump operation and extended impeller life.
  • Pump-servicing features include easy-to-disassemble pump, driveshaft and driven coupling, and an easily accessible driveshaft-bearing grease fitting.


Hull

  • Hull design provides exceptional low- and high-speed cornering ability without sacrificing top-speed performance.
  • Dry-sump design allows the engine to be mounted low in the hull, resulting in a very low center of gravity that contributes to exceptional handling performance.
  • Sponson design further contributes to the AquaTrax’s low-speed maneuverability and high-speed stability, giving the two-passenger R-12X/R-12 an even more aggressive cornering character than the three-passenger models.
  • Ride plate designed for more agility and light feel.
  • 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 and encapsulated styrofoam increase hull rigidity more than 200 percent compared to a single-hull design.
  • The AquaTrax hull is designed to be a stable platform for mounting from deep water and to be easily uprighted in case of accidental overturn.
  • Footwell and rear-deck areas have an anti-slip surface to provide sure-footed comfort when mounting, operating and dismounting the AquaTrax.
  • Forward-located, large-capacity 16.6-gallon 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.
  • Storage is available in two sealed compartments, with a 5.2-gallon front storage box located under the front hood and a 0.6-gallon compartment located in front of the rider.


Additional Features

  • Honda’s lever-style quick-trim system provides for lightning-quick bow-angle changes. The quick-trim system is cable-activated by pulling a lever mounted on the left handlebar which positions the nozzle instantly.
  • An ECU-controlled off-throttle steering system (OTS) is provided to help the AquaTrax turn in certain conditions when the handlebars are turned and the throttle is closed.
  • 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 if the hull is accidentally overturned.
  • The 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 multifunction display when activated, and can be reset with push-button controls.
