The pickup is maybe on the outdrive. Got a 4.3 Mercruiser for power? The speed pickup is in the leading edge of the lower unit and a tube/hose connects from the lower unit to the transom and up to the speedo.
Or you have one of these mounted on the bottom of the transom with the hose from the pitot through the transom and up to the speedo.
Thanks for reply - yes have 4.3 L MPI - Tra some is clean except for trim tabs - I had the impeller done - could the speedo pickup been detached as part of that process?
