Kelly from Jax 0 Report post Posted May 26, 2020 I'm not familiar in with the that particular boat but I have owned several boats and have some general advice. Normally the speedometer measures speed based on pressure it senses from a small tube between the gauge and the stern of the boat. On some models the tube intake is built into the outdrive. Debris can clog the little hole in the outdrive. Use a paper clip to clear it. Sometimes it is a separate intake tube that hangs off the back of the the boat. It has a hinge has sometime gets pulled up. Put it back down when that happens. Sometimes the hose gets detached from the intake. It hasn't happened to me but I suppose it is possible for power to the gauge to disconnected. Just some things to check... Share this post Link to post Share on other sites
