    Hi forum, Last year my speedo worked fine, Put it in storage for winter, (California non-freezing area) And now it does not work... Checked behind speedo, all hooked up, check fitting on the Alpha drive, also hooked up.. I unhooked it and tried my hardest to blow in and my son said it went up to 2 or 3 mph... Also, I sucked on the tube and put my tongue on it and it held suction... What gives?? Thanks!

    The actual pickup point for the speedometer is a small hole on the leading edge of the outdrive, just below the anitcavitation plate. Easy for that hole to get plugged with debris, take a small drill bit, piece of wire etc and ream it out - don't use a drill, do it by hand.
