ABSTRACT:
A number of embodiments of marine outboard drives having conduitry for conveying a water pressure signal through the outboard drive housings to a remotely positioned indicator for speed indication. The conduitry of the outboard drive is formed by first and second conduits formed respectively in the lower and upper unit housings of the outboard drive and which communicate with each other upon assembly. A flexible conduit conveys the pressure signal from the second conduit to the remotely positioned indicator and one end of this flexible conduit is affixed to the upper unit housing before the housings are assembled together to provide a neat, compact and easily assembled arrangement.
