Can someone with this outboard tell me if there is a hookup on the engine, hole on front leading edge of lower unit for a speedometer hookup. I am not seeing a small hole to indicate such a hookup. Maybe a pitot tube needs to be installed on the lower transom? Please help. There is a speedometer in the dash that is hooked up but not working because of mice chewing through the tubing. Just not sure if this motor has the hole in the lower unit. Cant seem to find the hose from the speedometer to the engine?
