The 2008 SX230 High Output is powered by a pair of 160 horsepower four-cylinder four-stroke MR-1 marine engines, legendary for their reliability. The internal propulsion system is one of the most important features of the SX230 High Output. Aside from mechanical simplicity and the ability to put the boat on plane very quickly, it offers two other major benefits: there’s no exposed propeller, so you can eliminate the associated fear and anxiety and a shallow draft and minimal risk of damaging running gear should you go astray.

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. The lubrication of the engine uses two oil pumps to deliver and return lubricated oil to each moving part of the engine with water-jacketed sump and oil backflow protection. The ignition timing, fuel injection mapping and engine diagnostics are controlled by an integrated, computerized management system. The engine is protected from harmful galvanic corrosion by sacrificial zinc anodes. 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.

The 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. A combination of zinc and copper alloys, developed by Yamaha marine engineers, that offers excellent corrosion protection for the propulsion system. For high durability of the propulsion system the Yamaha engineers designed a cooling water intake filter that filters out harmful debris that could cause blockage of important cooling water passages

The 2008 Yamaha SX230 High Output has a real nice profile, and its relatively high freeboard provides a feeling of security when on board.

The hull and deck are constructed of multiple layers of fiberglass with sandwich core construction reinforcements. The fiberglass layers are separately constructed – a revolution in boat design – combining the floor, stringer, and engine mounting system. The boat is constructed from a custom blended polyester resin with engineered fiberglass laminates and 3/8 in. 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.


The aft deck area of the SX230 High Output is roomy, comfortable, and easy to access from the cockpit or the water. The design encourages this to be the center of activities. The seating is comfortable, and there’s a mount for the standard cocktail table in just the right place.

Ten storage compartments include an enclosed head compartment (boat is not equipped with portable toilet), anchor storage compartment, storage under each seat and carpeted compartments under the starboard and port consoles. The SX230 High Output is also equipped with a full-size ski locker that accommodates skis, kneeboards or wakeboards. Stern storage is perfect for wet items, like ropes and wetsuits.

The swim platform of the Yamaha SX230 High Output can be transformed into a private patio on the water with room for a dinette table.

The J-shaped seating with a convertible lounger provides excellent comfort and versatility. The fully upholstered, flip-up captain seat provides a different, elevated view of your surroundings.

Drink holders are located at all seat locations for easy access for everyone on board and an ice chest keeps beverages chilled and sandwiches fresh while you are riding on the water.

High quality stereo and four speakers guarantee you’ll always have the right soundtrack on the water while you are hiding from the sun under the bimini top.

The helm features 4 in. dual tachometers, 2 in. fuel level gauge, low-fuel warning light, and depth finder that digitally monitors water depth from any spot on the water. The adjustable steering wheel allows the operator to adjust the angle of the steering wheel for added comfort while the independent dual engine controls adjusts each throttle position and control forward, neutral and reverse

Every SX230 High Output comes complete with a custom matching painted trailer with swing-away tongue for easy storage.

Test drive

Everything about the SX230 High Output has a good, solid feel of quality. The SX230 High Output was designed with a higher freeboard that shields riders from wind for a quieter, more comfortable ride.

On a day not quail perfect for speed the SX230 can reach 30 mph in 4.8 seconds and a top speed of 50 mph. The optimal cruising speed that allows you to travel 168 miles is 28.4 mpg
