Sierra 18-6782 Tilt/Trim Motor, Replaces Yamaha 61A-43880-01-00, 61A-43880-02-00, for 225-250 HP Outboards

The Sierra 18-6782 is a tilt/trim motor built for Yamaha outboard engines in the 225-250 HP range. It is a direct replacement for the original tilt/trim motor on these outboards, restoring reliable power to the trim and tilt system that raises and lowers the outboard and adjusts running angle on the water. The unit uses a 3-bolt mount and a 4-wire connection, matching the factory electrical and mounting configuration so it installs in the same location as the original motor. An O-ring is included with the motor, providing the seal needed at the mounting interface to keep water out of the trim system housing during installation.

Sierra engineers this motor to meet or exceed the performance of the original equipment part it replaces, built to hold up to the vibration, moisture, and load cycles of a marine tilt/trim system. It carries Sierra's Customer Satisfaction Warranty, which covers the product against defects in workmanship and materials for its useful life. The 18-6782 is intended for Yamaha outboards rated 225-250 HP and cross-references directly to the Yamaha OEM part numbers listed below, making it straightforward to match against a failed original motor.
