Mercury – Fused Bow Trim Harness | Fuse Adapter | 84-8M0169503

Overview
This fused bow trim harness is a simple adapter used to bring fused protection into a bow-mounted trim circuit. It’s meant for setups where you need a fuse in-line rather than running an unfused trim feed up front. The harness itself is just the fuse adapter—no extra wiring—so it drops into place cleanly. For V6 and V8 DTS engines, Mercury requires the L6SC fuse to be used with this adapter.

Key Features
    • Fuse Adapter Only – Provides in-line fused protection for bow trim circuits.
    • Bow Trim Use – Made for forward-mounted trim switches or panels.
    • V6/V8 DTS Requirement – Must be paired with an L6SC fuse on those engines.
    • OEM Connector – Factory-style plug that seats securely.
    • Compact Layout – Easy to place without crowding the rigging bay.

Engine & Boat Compatibility
    • V6 DTS
    • V8 DTS
    • Bow-mounted trim circuits

Performance & Practical Benefits
Adding fused protection keeps the bow trim switch from feeding an unprotected circuit, which reduces the chance of electrical issues down the line. The adapter fits neatly into the run so you don’t have to build your own splice or fuse holder. It keeps the trim wiring tidy and makes service easier since the fuse sits exactly where Mercury expects it to be.

Why Buy OEM
OEM adapters match Mercury’s fuse spec and connector layout, so you avoid loose fits or odd trim behavior. They’re built for the heat and vibration of the bow area and hold up better than generic parts. It’s a small piece, but it keeps the system reliable.
