This document is the Owner's Manual for Yamaha F150G, FL150G, F175C, FL175C, F200G, and FL200G outboard motors. It provides essential information for proper operation, maintenance, and care of these engines.
Function Description:
The Yamaha F150G, FL150G, F175C, FL175C, F200G, and FL200G are 4-stroke DOHC L4 16-valve outboard motors designed for marine propulsion. They are equipped with an electric starter and fuel injection system. These models feature a digital electronic control system that manages shifting, throttle, and other electrical operations, including a start-in-gear protection device that prevents the engine from starting unless it is in neutral. The power trim and tilt system allows for adjustment of the outboard motor's angle relative to the transom, optimizing performance, fuel economy, and protecting the propeller and lower case from damage in shallow water. Some models may include a Yamaha Security System (Y-COP) for theft protection, consisting of a receiver and remote control transmitters. The engines are designed with a cooling water passage flushing device for easy maintenance.

Usage Features:
- Digital Electronic Control: Provides precise control over shifting and throttle. The control lever allows for engaging forward, neutral, and reverse gears, and adjusting throttle. A free throttle switch enables throttle operation in neutral without engaging gear.
- Start/Stop Switch Panel: Allows for starting and stopping the engine(s). For twin engine setups, individual or all engines can be controlled.
- Engine Shut-off Cord (Lanyard): A safety feature that stops the engine if the operator falls overboard or leaves the helm, preventing runaway boat incidents.
- Trolling Speed Adjustment: Allows for fine-tuning trolling speed between 600 r/min and 1000 r/min in 50 r/min increments when the control lever is in gear and throttle is fully closed.
- Multi-Display Gauges (6Y9 Multifunction Color Gauge, 6YC Multifunction meter, 6Y8 Multifunction meters): Provide comprehensive engine status and alert information, including engine warm-up, synchronization, overheat, low oil pressure, water separator, low battery voltage, and engine trouble alerts.
- Propeller Selection: Critical for optimal performance, fuel economy, and engine life. Yamaha offers propellers suitable for various applications, including those with the "Shift Dampener System (SDS)".
- Shallow Water Cruising: The power trim and tilt system allows for partial tilting of the outboard motor to navigate shallow waters, protecting the propeller and lower unit.
Maintenance Features:
- Periodic Maintenance Charts: Detailed schedules for inspections and replacements, categorized by operating hours (20, 100, 300, 500 hours) or time intervals (3 months, 1 year, 3 years, 5 years).
