The speedometer on my 1996 Mercruiser 5.7L with Alpha One Gen 2 drive operates poorly. It does register, but inconsistently and at least 15 MPH below actual speed. Since I'm fairly inexperienced, are there any easy things I can do to fix it?
about the only thing you can do is be sure the hole in the drive is clear<br /><br />you can blow out the line from the speedo back and be sure the tubeing is not kinked<br /><br /><br />for the most part the speedos are of very low quality <br /><br /> the good ones like airguide speedometers work very well but they went out of Business<br /><br />tommays
You have something clogging the tube. Disconnect and blow it out from one end, and then the other end. Royal pain in the a$$ those speedo tubes.<br />Search this post for hundreds of entries on this topic.
