2007 Yamaha SX230 High Output Sportboat

The flagship boat in our Bowrider Series, the 320-horsepower, 23- foot SX230 High Output was designed to give your family the ultimate balance of luxury and performance. One ride in this boat and you’ll experience unbelievably responsive acceleration and speed.

And features like a satellite-ready JBL Marine sound system with four speakers, bimini top, comfortable seating for ten people, and an innovative swim platform with Turf® mats make cruising around with family and friends an absolute blast.

The Powerplant

The SX230 High Output is powered by two Yamaha High Output MR-1™ engines that deliver a combined 320 horsepower. These 1052cc four cylinder, four-stroke Yamaha marine engines deliver excellent power in a compact package.
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 High Output 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.
