• PDF download covering 1999–2003 Yamaha V6 outboards (150HP through 200HP), including 130TXRA, DX150, LX150, LX200, PX150, SX150, SX200, and VX150 series.
• Original OEM publication (Part number: 67H28197Z811, dated October 1998).
• Features 35 exploded-view assembly diagrams and 15 electrical reference tables.
• Serves as the foundational reference for all documented V6 2-stroke variants.
• Details complete component overhauls for the vapor separator, stator assembly, CDI unit, throttle position sensor, high-pressure fuel pump, reed valves, and the oil injection system.
• Includes step-by-step instructions to help you avoid expensive workshop visits, covering throttle valve synchronization, engine idling speed adjustment, shift cable calibration, oil injection system bleeding, gear backlash shimming, power trim and tilt inspection, and precise wiring diagrams.

Shop-Floor Reference and System Documentation

This 380-page service publication details the maintenance and mechanical inspection procedures required for the V6 series. Inside, you get a comprehensive breakdown of the power unit assembly (including the crankcase, crankshaft, and piston assemblies), lower unit maintenance, bracket systems, and complete electrical schematics. Whether you are tracing a wiring fault or comparing fuel system diagnostics on the bench, the extensive troubleshooting section helps you isolate performance issues efficiently and get the outboard back in the water. By providing exact factory multimeter readings and pinpoint test parameters, this reference eliminates diagnostic guesswork. It delivers procedural clarity for tasks that typically require a dealer visit, saving you from expensive workshop labor rates during any repair.

Critical Specifications and Factory Tolerances

Expect precise technical data for the 2.596 L engine architecture. The documentation covers critical required values, including the flywheel magnet assembly nut torque (190 Nm / 137 ft-lb) and the exact fuel pressure for the high-pressure line (250 kPa / 35.6 psi for EFI systems). You will also find the cylinder head warpage limit (0.1 mm / 0.004 in) and standard internal tank oil capacity (0.9 L). The ignition coil output is listed at a standard 12 V for baseline electrical testing.

Reference how factory workshop documentation is structured for additional insight into assembly conventions. Working with marine fuel injection systems and high-torque powerhead components carries inherent risks; always verify tolerances and procedures with a certified marine technician to maintain a safe working environment.
