Mercury – Pitot/Speed Sensor Kit | 100 PSI SmartCraft Speed Input | 881879A13

Overview

For boats that run under 80 mph and rely on SmartCraft for speed data, this kit makes the whole setup easier and more complete. The Mercury 881879A13 Pitot/Speed Sensor Kit delivers a 100 PSI water-pressure speed signal and includes the harnessing needed for today’s 10-pin rigging layouts. It mounts cleanly on the MerCruiser sterndrive transom bracket or directly on the hull near the engine, giving SmartCraft gauges a steady, dependable speed reading without depending on GPS or paddle wheels.

• MerCruiser sterndrive transom bracket or hull-mounted installations

Performance & Practical Benefits

This kit brings together the sensor and the harnessing you need for current 10-pin SmartCraft setups, eliminating the usual guesswork that comes with pitot-style speed installations. The 100 PSI rating keeps the readings stable through the boat’s usable speed range, and the included harnesses ensure the signal reaches the network cleanly. Once installed, SmartCraft gauges respond quickly to pressure changes, giving you consistent and reliable speed data.

Why Buy OEM

Water-pressure speed sensors take a beating, and accuracy matters. Mercury’s OEM sensor is built for clean SmartCraft communication and long service life. The included harnesses guarantee proper pin alignment and shielding—critical for avoiding the intermittent readings and wiring headaches that come with aftermarket parts. This all-in-one kit ensures everything fits and works as intended.

FAQ

Q1: What makes this kit different from the standard 100 PSI pitot kit?
It includes the two SmartCraft harnesses needed for modern 10-pin rigging layouts, so installation is plug-and-play.

Q2: Can this replace GPS or paddle-wheel speed readings?
Yes. It provides a water-pressure-based SmartCraft speed signal on its own.

Q3: Where should I mount the sensor?
Either on the MerCruiser sterndrive transom bracket or on the hull near the engine in clean water flow.

Q4: Is this kit compatible with older 3-pin or 4-pin systems?
It’s meant for current 10-pin applications—older systems may require different harnessing.

Q5: Does it work with Mercury Racing engines?
Yes. It’s fully compatible with all SmartCraft-ready Racing models.
