Sierra 18-6765 Tilt/Trim Assembly, Replaces 828708 & 878265A4, for Mercury/Mariner 135-250 HP & 105-140 HP Jet Outboards 1996 & Up

The Sierra 18-6765 is a tilt/trim assembly built for most late-model Mercury and Mariner outboard motors from 1996 and up. It replaces the tilt/trim system on a wide range of Mercury/Mariner outboards, including 135, 150, 175, 200, 225, and 250 HP models, the XR6 Mag III, and 105-140 HP Jet outboards, giving boaters a direct source for restoring smooth, reliable power tilt and trim function on these engines.

This assembly directly replaces Mercury/Mariner OEM part numbers 828708 and 878265A4, so it installs as a like-for-like unit on applicable outboards without requiring a mix of separate components. Sierra engineers its tilt/trim assemblies to meet or exceed the specifications of the original equipment they replace, and every Sierra part is backed by Sierra's Industry Leading Customer Satisfaction Warranty, which covers defects in workmanship and materials for the useful life of the product.

At 8.77 pounds, the 18-6765 is sized and weighted consistent with a complete outboard tilt/trim assembly rather than a single component, and it operates on the standard 12-volt electrical systems used on the covered Mercury/Mariner outboards.
