2007 Yamaha Marine AR230 HO Standard Features


The Powerplant
The AR230 High Output is powered by two, Yamaha High Output MR-1™ engines. These 1052cc four cylinder, four-stroke Yamaha marine engines deliver excellent power in a lightweight, 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 AR230 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.

Boat Of the Year 2007

The jet boat has grown up. Once a rowdy, raucous puppy chasing around the lake, nipping at the heels of “real” boats, the jet-powered runabout has matured into a well-mannered craft. In fact, with this boat, the time has come to drop the qualifier. It’s a runabout. One that not only holds its own among the reigning stern drives but, in many ways, betters them.

We’ve thought highly of the 23' Yamaha since it debuted in 2003, but the all-new version rolled out for 2007 blew us—and you—away, becoming the flat-out best-seller in its class. For 2008, the tower-equipped AR230 High Output is priced at about $40,000. That’s a whopping $20,000 less than most of the popular runabouts in the ultra-competitive 22'-to-24' range. And though its low price makes it an attractive value for boating families, what sold us—and you—is the boat’s innovative design and fresh thinking.

What hits you right off is the boat’s transom. Yamaha designers watched how we use runabouts and saw that when not underway, we congregate in the stern. So why not make the aft platform area the center of activity?

0712_boat_year_interior.jpgThe low profile of the Yamaha engines made it possible to design a 4'-deep platform that’s arranged on two levels to create a comfortable lounging area. The latest version features curved and padded vertical surfaces for backrests and horizontal surfaces covered in soft HydroTurf material that’s easy on the feet and knees. A wide hatch in the upper level of the platform covers a wet-stowage compartment that can handle lines and fenders, swim fins, and other gear. The lower level has a pedestal socket for a table, and a new optional extension for the standard Bimini top provides shade. There’s even a remote for the stereo.

It’s a design that can’t be duplicated on a stern drive–powered boat, which has a much taller engine sitting right up against the transom.

There’s also the feeling of safety offered by the jet drives, which are tucked far under the stern of the boat—away from the feet of young swimmers. Those drives give this boat its shallow draft and make it easy to beach. But they come with disadvantages as well. At no-wake speeds this keelless boat wanders in a cross wind and can be tricky to maneuver around a dock, and top speed is slightly limited due to the lack of drive trim. But the self-draining engines and drives are easy to maintain, and the acceleration and midrange handling rival those of an inboard skiboat. Or even a waterbike.

Yamaha has been building jet-powered boats at its Vonore, Tennessee, plant since it introduced the weird little Exciter 220 in 1996. We’ve watched the quality steadily improve, and today fit-and-finish is first rate. Yamaha has worked hard to learn the boatbuilding business. For 2008, it will offer a more luxurious version of the 230 platform with the 232 Limited, along with the standard SX230 and the AR230.

And the future looks bright, too. There’s a new 1.8-liter supercharged engine in the Yamaha FX SHO waterbike this year that makes about 250 hp. Sounds like the perfect powertrain for a new generation of Yamaha boats. We can’t wait.
