2003 Yamaha Two Stroke Service and Repair Manual

The 150TXRB is the engine documented here, a 2003 two stroke, and its service information was published by Yamaha as LIT-18616-01-87. Coverage takes in the 1998 and 2003 model years, which means the book was written once and reissued rather than rewritten for each season.

It also appears under the general Outboard listing in the catalogue.

The code on the clamp bracket plate should read 150TXRB in full. The X and R positions matter, since shaft length and rotation change parts and procedures on a V6 unit.

Specification tables with service limits, torque values printed with each assembly step, carburetion and ignition timing, powerhead disassembly and measurement, gearcase shimming and backlash, tilt and trim hydraulics, wiring references, and symptom based troubleshooting as Yamaha wrote it for dealers.
