• Official Honda Motor Co., Ltd. service publication P/N 66ZW900, dated January 2001
• Covers 2001 Honda BF8D, BF9.9D, and BF10D outboard motors, including BFP-series Power Thrust variants with Short, Long, and Extra Long shaft configurations
• 383-page factory reference spanning 18 chapters with detailed exploded-view diagrams, torque reference tables, and wiring schematics

Manual Content and Structure

This factory reference is built for the bench. It breaks down the 2001 Honda BF8D, BF9.9D, and BF10D outboard series into highly detailed chapters, giving you clear visibility into core systems like the engine block, fuel delivery, electrical equipment, gear case, and both tiller and remote control mechanisms. High-resolution exploded-view diagrams map out internal components down to the last washer. Whether you are inspecting the crankshaft, testing the oil pump, or rebuilding the lower unit, the schematics show exactly how parts interlock. Maintenance schedules are also included to define strict service intervals based on actual engine hours. Marine environments are unforgiving, and working on outboard fuel or electrical systems carries inherent risks. Always follow factory-prescribed safety protocols and verify component baselines before operating the engine on the water.

Specification and Reference Data

Accurate data eliminates guesswork in the shop. The manual organizes technical specifications by system to speed up component evaluation and diagnostics. You will find exact baseline figures rather than generic estimates. Cylinder compression is documented at 1.23–1.42 MPa. The flywheel nut requires a precise torque of 88 N-m (65 lbf-ft). It also covers operational metrics like the 377 g/kWh fuel consumption rate and the 1.0-liter SAE 10W-30 oil capacity requirement. For electrical diagnostics, the text details 12A charge coil specifications alongside exact sensor resistance thresholds. Relying on this specific 66ZW900-series documentation ensures you have the exact torque yields and clearances needed to maintain these outboards to original OEM standards.
