the speedometer pitot is located near the outdrive. I am trying to identify a tiny pinhole in the outdrive on the side of housing near the bottom near the nose cone.

I think it's to let any residual water from the drive when you pull it out of the water {winter]J.

Re: merc alpha 1 outdrive

tysick, when you say "the speedometer pitot is located near the outdrive" are you talking about an add-on speedometer pitot that bolts onto the transom? I know some of the alpha ones have a built in pitot for the speedometer, and some do not. (Mine doesn't).
