2007 Yamaha Marine SR230 HO Standard Features


The Powerplant
The SR230 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 SR230 High Output 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.
