I have a 5.7L Merc I/O with an Alpha One outdrive and my Speedo is not working. Would any of you have an idea where the cable woudl be located and where I should check besides in the dash? Does it connect to the engine??

Re: Speedometer Cable

It has no speedodmeter cable. It only has a small hose that puts pressure on the guage from water flowing by. Make sure the hose is connected at both ends then clean out the Pitot tube if it has one. If it does not then clean out the debree from the hole in front of the outdrive below the cavitation plate.
