Description YAMAHA F80B and F100D Trim Motors

Overview

A key component of the hydraulic trim system, this YAMAHA electric motor drives the hydraulic pump responsible for raising and tilting the outboard motor. A faulty motor is indicated by slow operation, unusual noise, or a complete lack of response.

Technical Specifications

Trim motor for YAMAHA F75B, F80B, F90B, F100D (2005 and later)

Part Numbers: 6D8-43880-00-00, 6D8-43880-01-00, 6D8-43880-08-00, 6D8-43880-09-00, ST-0340, PT627NM

Recommended Operating Conditions

This trim motor is intended for use on outboard motors in a marine environment. It must be installed in the dry conditions of the trim housing, protected from direct immersion. Before installation, it is essential to verify compatibility using the motor’s serial number. The electrical connection must respect the original polarity to prevent damage. Light lubrication of the contacts is recommended during installation.

Technical Benefits

Complete restoration of the electrical operation of the hydraulic trim circuit
Resistance to vibrations and mechanical shocks inherent in marine use
Protection of the windings against moisture thanks to the original housing
Guaranteed compatibility with the original outboard motor’s connectors and mounting hardware
Easy replacement, with no modifications to existing wiring required

Usage and Maintenance Tips

Check the condition of the brushes and commutator before replacing the entire motor: sometimes only the brushes are worn
Rinse and dry the trim housing before installation to prevent premature corrosion
Apply dielectric grease to the electrical connectors to prevent oxidation
Operate the trim system several times after installation to bleed air from the circuit
Periodically check the hydraulic fluid level in the trim reservoir

FAQ

How can you tell the difference between a trim motor failure and a hydraulic failure?

A simple test can help distinguish between the two: if the trim motor is running (audible noise) but the system does not move or moves only slightly, the problem is hydraulic (pump, cylinders, fluid). If the motor makes no noise despite a proper power supply, the problem is electrical (motor, relay, fuse).

Is the motor serial number really necessary to place an order?

Yes, it is essential for YAMAHA motors. Series updates and manufacturer modifications have led to changes in components that are sometimes not visible to the naked eye. Verifying the serial number helps prevent ordering an incompatible part, a costly product return, and prolonged downtime for the boat.

What is the service life of a YAMAHA trim motor?

The service life of a trim motor depends heavily on the overall maintenance of the hydraulic system, frequency of use, and sailing conditions. On a well-maintained motor that is regularly flushed with fresh water, a trim motor can operate without issues for 10 to 15 years. Premature failures are often due to corrosion of electrical contacts or contamination of the hydraulic system.
