1. COMMON MODEL INFORMATION MOTOR SELECTION AN TI-V E N TI LATlO N PLATE H E I G HT Secure and correct outboard motor set-up is essential for safe boating and good performance. Follow the installation instructions provided in this guide. I NOTICE I I - _ Do not use an air impact tool to tighten or loosen the transom bolts. Using an air impact tool to tighten or loosen the transom bolts can generate enough heat to damage the bolt threads. The air impact tool can also produce enough tightening torque to damage the boat transom. Before installation, be sure the outboard motor does not exceed the recommended maximum horsepower for the boat.
Refer to the boat's certification plate for recommended maximum horsepower. For most applications, the outboard motor should provide 80% of the recommended maximum horsepower for the boat. If the certification plate information is not available, contact the boat dealer or manufacturer. Refer to the dimensional drawings in the appropriate Honda Marine Shop Manual to be sure there is nothing on the boat that will interfere with outboard motor tilt-up and steering. On a dual motor installation when the minimum distance between motors is used, the engine cover of one motor June interfere with the adjacent motor if only one motor is tilted up when the boat is steered full right or full left.
1 NOTICE I BOAT TRANSOM BOAT TRANSOM Install the outboard on the center of the transom securely, and be sure the boat is well-balanced. PLATE As a general rule, the outboard should be mounted so the anti-ventilation plate is parallel to and on the same plane as the boat bottom or slightly higher. If the boat transom angle is less than 8" (4" on BF8D/9.9D, BF15D/BF20D and BF25A/30A; 12" on BF200A/225A), the anti-ventilation plate will not be parallel to the boat bottom when trimmed to the lowest hole. Do not tilt one motor up when the boat is steered full right or full lee, or the engine cover June be damaged. 5 in.
With the boat loaded and unmoving, and the outboard perpendicular to the water, ensure a minimum 5 in. clearance exists from the idle exhaust ports to the water level. Refer to the boat specifications for details. Date of Issue: June 2003 0 2001-2003 American Honda Motor Co., Inc. 1120
