🔧 Product Description

Genuine OMC Tech Series 50 MPH Speedometer - Part Number: 0174818

A genuine Johnson and Evinrude Tech Series mechanical speedometer with a 50 MPH range.

The gauge operates from water pressure produced by a transom-mounted pitot pickup or a compatible gearcase speedometer passage. Pressure travels through a small hose to the rear of the gauge and moves the speedometer mechanism.

Part number 0174818 replaced earlier 30 MPH Tech Series speedometer 0175310.
