Sierra 18-6767-1 Tilt/Trim Motor, Replaces 172850, 173564, 173596, for Evinrude 2/3/4 Cylinder Outboards

The Sierra 18-6767-1 is a replacement tilt/trim motor built for Evinrude outboards, supplied as the motor only. It is designed to restore power tilt and trim function on applications where the original motor has failed or worn out, and it includes an 18-7510 O-ring for a proper seal on installation.

This motor is a direct cross-reference for OEM numbers 172850, 173564, and 173596, and it covers a wide span of Evinrude configurations: 1974 115 HP and 135 HP models, most 45 HP commercial models from 1989-90, 2 cylinder applications from 1984-88, 3 cylinder applications from 1977-83, and 4 cylinder applications from 1974-77. Because it is supplied as the motor only, it is intended for installations where the existing reservoir and tilt/trim assembly are being reused; the motor and reservoir together are used on applications noted above. If a full internal rebuild of the trim unit is needed rather than a motor swap, the corresponding repair kit is 18-6252.

The unit measures 8.5 x 5.75 x 5.75 inches and weighs 5.7 pounds. It carries UPC 808282199197 and is identified under the Sierra part number 18-6767-1.
