01 310hp Yamaha 1800 LE

The five-person, 310-horsepower Yamaha® XR1800™ sport boat is the most powerful sport boat in the industry. The XR1800 is designed for the serious boater demanding world-class performance and styling in a recreational runabout. The XR1800 features two ultra-performance Yamaha marine engines that incorporate the most reliable exhaust emission and noise reduction systems in the industry. The engines are complimented by a high-performance hull design that delivers precise handling and exacting control. Also, its twin-engine design gives the XR1800 excellent "return to port" capability and its twin intake grates under the hull ensure that XR1800 hooks-up in all water conditions. The XR1800 comes with a long list of features that include full instrumentation, comfortable swivel seats, easy access jet pump clean-out ports and a high-quality trailer. apx 150 hrs

The Powerplant
The XR1800 is powered by two high-performance, 155 horsepower, three-cylinder, 1176cc Yamaha marine engines. Each powerplant is fueled by three 44mm Mikuni carburetors with two accelerator pumps that provide excellent throttle response throughout the total RPM range. Features include:

  • Yamaha Power Valve System — Computer controlled, electronic, variable exhaust port timing for maximum horsepower at all RPM ranges with no compromise to throttle response.
  • Ceramic-plated Cylinders — Optimal heat transfer, durable, accurate and consistent bore, lightweight.
  • Yamaha Loop-charged Combustion — Fuel mixture actually loops as it enters the combustion chamber, which helps distribute fuel/air mixture evenly for better combustion, performance and fuel economy.
  • Seven Port Cylinders — Allows for high efficiency of fuel/air mixture transfer to combustion chamber.
  • Accelerator Pumps — Maximum throttle response; no off-idle hesitation.
  • High-performance Tuned Exhaust Pipe — The equal flow manifold allows all cylinders to perform equally at peak performance. The exhaust chamber is specially designed to complement the Y.P.V.S. technology.
  • Variable Oil Injection — Regulates the fuel/oil mixture to deliver only what is needed at different RPM levels; reduces smoke and oil consumption.
  • Corrosion Protection System — Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) assure a long service life. Cylinders, cases and heads are all treated with a durable oxide coating to form a barrier between corrosion and expensive engine parts.
  • Electronically Controlled, Variable Ignition Timing — For exact ignition advance control at all throttle positions and RPMs.
  • Automatic Bilge Pump — Senses water presence and automatically turns on.

The Jet Pump Propulsion System
The XR1800 twin 155mm Hyper-Flow jet pump propulsion system with three-blade stainless steel impeller is designed to maximize water flow for high performance. The XR1800 twin pump configuration provides excellent hook-up and smooth acceleration in all water conditions. Features include:

  • Pumps are Manufactured with YDC30 — A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection.
  • Stainless Steel Impeller Housing Liner — For high durability, the liner maintains accurate clearance tolerances between the impeller and the housing.
  • High Flow Intake Duct and Grate — The dynamic shape of these items directs water flow into the pump for better thrust, performance and hook-up.
  • Cooling Water Intake Filter — Filters out harmful debris that could cause blockage of important cooling water passages.
  • Jet Pump Clean-out Plugs with Push Button — Allows for direct access to the inlet duct cavity to easily clear any debris from the pumps.

The Hull and Deck
The fiberglass construction of the hull and deck represents some of the best technology in the industry today. The hull and deck are constructed of multiple layers of fiberglass with sandwich core construction reinforcements. The fiberglass stringer is separately constructed, laminated into the hull and then injected with floatation foam to provide 100% floatation safety as well as longitudinal and lateral structural rigidity.

The engine bed, which represents a revolution in boat design, is a separate fiberglass part bonded into the hull with polyurethane adhesive then laminated to the hull and stringer system. This separate engine bed also isolates and protects the engines from any water in the bilge area of the boat as well as providing isolation from engine vibration and noise. The deck is then fastened to the hull with both mechanical fasteners and polyurethane adhesive giving this revolutionary semi-monocoque fiberglass structure unsurpassed strength and rigidity.

Environmentally-minded Innovations
By employing proven technologies, Yamaha delivers significant reductions in emissions output and noise levels without compromising performance and reliability. These technologies include:

  • Yamaha Sound Suppression System — This system of integrated noise reduction components targets the three common types of noise: 1.) intake noise, 2.) exhaust noise and 3.) noise from vibration.
  • Yamaha Platinum Plus System — The Yamaha Platinum Plus System is a high-tech, automotive-based catalyst that is artfully integrated into the exhaust system.

Added Features
The XR1800 comes with a long list of comfort features that make it one of the most complete sport boats offered today. These features include:

  • 322 Gallons of Total Storage — Seven storage compartments includes a cavernous 142 gallons of storage space under the bow with integrated tie-down eyes to secure a full-size carry-on ice chest. A full-size ski locker accommodates skis, kneeboards or wakeboards. A convenient storage tray under the motor hood is ideal for life jackets, duffel bags and small coolers. The stern clean-out compartment easily accommodates ski ropes, dock lines or bumpers. Storage is also available under each articulating windscreen and in the dash glove box.
  • Yamaha Enunciator Panel System — A series of lights and audible warning systems, which alerts the operator of engine overheating, low fuel and low oil.
  • Independent, Dual Engine Controls — Controls forward, neutral and reverse.
  • Driver's Side Adjustable Mirror — Automotive style and convenience.
  • Custom Bucket, Fully Adjustable Seats with Swivel — Two high-back swivel seats provide comfort and versatility.
  • Integrated Drink Holders — Located at all seat locations for easy access for everyone on board.
  • Swim Platform with Self-retracting Re-boarding Ladder — For easy boarding while in deep water.
  • High-quality Trailer — Every XR1800 comes complete with a matching painted trailer.
