Important Fitment Note

Do not select this control by Mercury engine horsepower alone. Fitment is determined by the boat's rigging configuration.

This control is specifically for compatible installations requiring a Mercury 8-pin electrical connection, Gen 1-style mechanical throttle and shift cables, and a 15-foot harness.

A similar-looking Mercury control may use a 14-pin connector, Gen 2 control cables, a different harness length, or a different mounting arrangement. Verify the existing control before ordering.

OEM and Cross Reference Numbers

Pro Marine 881170A15P cross-references the following Mercury side-mount remote-control numbers.

What This Control is Used For

The side-mount remote control provides helm operation of the mechanical throttle and shift system on compatible Mercury outboard installations.

The control mounts on the side of the helm or console and connects to the engine rigging through the required Mercury electrical harness and Gen 1-style mechanical control cables.

The control also provides convenient power trim and tilt operation from the control handle on the compatible installation.

Mercury Rigging Fitment

Fitment for 881170A15P should be determined by the complete rigging configuration rather than by a broad Mercury horsepower range.

8-Pin vs. 14-Pin Mercury Controls

Mercury side-mount controls are available with different electrical harness configurations. The 881170A15P is the 8-pin version.

Do not confuse this part with Pro Marine 881170A13P, which is intended for a different 14-pin Mercury electrical configuration. Connector type should always be verified before ordering.

Gen 1 Mechanical Control Cable Application

This remote control is specifically identified for compatible Gen 1-style Mercury control cables.

Gen 1 and Gen 2 control systems use different cable attachment configurations. Do not assume interchangeability based only on the appearance of the control box.

Common Replacement Reasons

• Original Mercury side-mount control is worn or damaged.
• Throttle or shift lever movement has become loose or unreliable.
• Control housing or handle is physically damaged.
• Power trim switch in the existing control no longer operates correctly.
• Electrical harness or internal control components are damaged.
• An older cross-reference control is being replaced during a rigging restoration.

Hard shifting or throttle movement can also result from damaged, corroded, binding, or incorrectly adjusted control cables. Inspect the complete control and cable system during diagnosis.

Installation Tips

• Disconnect battery power before working on the control or engine electrical system.
• Verify the original control uses the required Mercury 8-pin electrical connection.
• Confirm the installed throttle and shift cables use the correct Gen 1-style connections.
• Compare the replacement control and harness with the original before installation.
• Inspect existing control cables for stiffness, corrosion, kinks, or damage.
• Route the 15-foot harness without excessive tension, sharp bends, or chafing.
• Route mechanical cables with smooth bends to reduce control effort and binding.
• After installation, verify neutral, shift direction, throttle travel, trim operation, and overall control function.

Because remote-control installation directly affects throttle and shift operation, installation and adjustment should be performed by a qualified marine technician when the installer is not familiar with Mercury mechanical rigging.
