Mercury – Analog Trim Sender (Starboard Mount) | 40–115 HP Outboards | 8M0098264

Overview

A reliable trim sender makes a big difference when you’re running shallow, easing into a dock, or trimming the boat for a smoother ride. The Mercury 8M0098264 Analog Trim Sender brings that steady feedback back to the helm. Mounted on the starboard side, it gives older analog gauge systems the clear, predictable trim reading they depend on. Once it’s in place, the gauge starts behaving the way it should—no jumpiness, no dead spots, just honest information about where the engine sits.

Key Features

• Starboard-Mount Design – Installs on the starboard side for engines built for this layout.
• Analog Gauge Output – Sends clean, steady trim information to traditional dash gauges.
• Natural Finish – Features an unpainted natural housing as used on factory assemblies.
• 40–115 HP Coverage – Built for the 40–60 Family 2 and 75–115 EFI outboards.
• Smooth Signal Response – Tracks engine trim position without lag or fluctuation.
• Direct Replacement – Uses factory-style mounting points and wiring for easy installation.

Engine & Boat Compatibility

• 40–60 HP Family 2 Four Stroke
• 75 EFI Four Stroke
• 90 EFI Four Stroke
• 115 EFI Four Stroke

Performance & Practical Benefits

A properly working trim sender makes trimming feel intuitive again. With this unit installed, the gauge follows the engine movement smoothly, making it easier to find the right running attitude when the water turns choppy or when you need to lift the bow in shallow areas. The sender stays protected at the mount, holds calibration well, and provides predictable readings even after long seasons of vibration and exposure. It’s a simple part, but it restores a sense of control you can feel at the helm.

Why Buy OEM

Analog senders need tight tolerances to deliver a smooth, accurate signal. Mercury’s OEM version matches the engine’s movement exactly and communicates cleanly with the gauge. Aftermarket versions often introduce signal noise or fail prematurely, especially in saltwater. With the OEM unit, you get a direct fit, reliable calibration, and long-term performance you won’t have to revisit.

FAQ

Q1: What symptoms suggest the trim sender needs replacement?
If the gauge sticks, jumps, or no longer matches the engine angle, the sender is usually worn or water-intruded.

Q2: Is the starboard mount location important?
Yes. This model is engineered specifically for starboard-side mounting on eligible engines.

Q3: Will this improve gauge accuracy right away?
Most installations show accurate, steady readings as soon as the sender is aligned and connected.

Q4: Does it require calibration after install?
No full calibration is required, but adjusting the sender position during installation ensures proper gauge travel.

Q5: Is this sender suitable for saltwater?
Yes. When installed correctly, the housing and internal components hold up well in both saltwater and freshwater conditions.
