2006 YAMAHA SX230

It’s obvious the SX230 is a great deal of boat for the money. It’s 23-feet long, roomy enough for ten people and powered by a 280-horsepower internal propulsion system. This boat is loaded with features, like an award-winning integrated swim platform, a satellite-ready JBL Marine sound system, a dinette table with two mounts, flip-up captain’s chairs, and Yamaha’s “No-Wake” Mode for easy slow-speed maneuvering. One ride and your family will know the true meaning of togetherness. OPTIONS INCLUDED: Bimini Top; AM/FM Stereo CD; Battery Switch; Shorelandr Trailer

Features & Benefits
The Powerplant
 The SX230 is powered by two Yamaha MR-1™ engines that provide 280 horsepower. These engines are four-cylinder, compact, ultra-lightweight DOHC, 20-valve and liquid-cooled for unequalled performance.  
  Electronic Fuel Injection (EFI): Four individually adjustable throttle bodies, throttle position sensor (TPS) and intake air pressure and air temperature sensors supply the optimum air/fuel mixture. The results are a smooth, high power output with low fuel consumption and low exhaust emissions.  
  Dry Sump Lubrication: Uses two engine oil pumps to deliver and return lubricated oil to each moving part with water-jacketed sump and oil backflow protection.  
  Yamaha Engine Management System (Y.E.M.S.): An integrated, computerized management system that controls and adjusts such functions as ignition timing, fuel injection mapping and engine diagnostics.  
 Independent Water-jacketed Exhaust Manifolds with Collector: Achieves high power while keeping noise and exhaust heat under control.  
  Thermostatic and Pressure Controlled Cooling System: Water flow through the engine is controlled by a thermostat and pressure system and is maintained by a pressure control valve.  
 Corrosion Protection System: Sacrificial zinc anodes protect the engine from harmful galvanic corrosion. Stainless steel fasteners (nuts, bolts, hardware) provide 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.  
The Jet Pump Propulsion System
 The SX230 twin 155mm hyper-flow jet pump propulsion system with three-blade stainless steel impeller is designed to maximize water flow for high performance. The twin pump configuration provides excellent hook-up and smooth acceleration.  
  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 from inside the boat.  
The Hull and Deck
 The SX230 utilizes a deep-V, multi-chine hull with 20-degree dead rise. The hull and deck are constructed of multiple layers of fiberglass with sandwich core construction reinforcements.  
 The fiberglass liner, which is separately constructed, represents a revolution in boat design, combining the floor, stringer, and engine mounting system. It is constructed from a custom blended polyester resin with engineered fiberglass laminates and 3/8" 6061-T6 aluminum plate for the engine mounts.  
 The liner is bonded into the hull with polyurethane adhesive and then injected with foam to provide maximum floatation as well as longitudinal and lateral structural rigidity. 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.  
Additional Features:
 Multiple Storage Compartments: Fifteen storage compartments include an anchor storage compartment, storage under each seat and carpeted compartments under the starboard and port consoles. The SX230 is also equipped with a full-size ski locker that accommodates skis or wakeboards. Two cockpit gunwale inserts provide additional storage for rear passengers. The convenient dual glove box is perfect for small items like keys and sunglasses.  
 Innovative Swim Platform: This award-winning stern can be transformed into a private patio on the water with room for a dinette table.  
 Adjustable Tilt Steering Wheel: Allows the operator to adjust the angle of the steering wheel for added comfort.  
 Center Walk-Thru Transom: Easy access to the stern patio area and swim platform from the cockpit.  
 Depth Finder: Digitally monitors water depth from any spot on the water.  
 Telescoping Re-boarding Ladder: For easy boarding while in the water.  
 Filler Cushions: Padded cushions turn cockpit and bow seating area into comfortable sundecks.  
 Independent, Dual Engine Controls: Adjusts each throttle position and control forward, neutral and reverse.  
 Ample Seating for 10: Two high-back captain seats, a large U-shaped bench seat and seating at the bow provide excellent comfort and versatility.  
 Flip-Up Seats: Two high-back, fully upholstered, flip-up captain seats provide a different, elevated view of your surroundings.  
 Marine Grade Carpet Kit: High-grade, removable carpet throughout the cockpit adds to the SX230’s comfort and great looks.  
 Bimini Top: Premium Stainless Steel construction with Sunbrella® material for better durability.  
 Integrated Drink Holders: Located at seat locations for easy access for everyone on board.  
  Premium AM/FM CD Stereo with Two Remote Controls: High quality stereo and four speakers with remote control at helm and stern, giving you access to the radio from the waterline.  
 High-quality Trailer: Every SX230 comes complete with a custom matching painted trailer.
