Why is my boat speedometer not working?
Besides, what causes a boat speedometer to stop working?
The usual cause is a clogged intake hole. That is either in the front of the lower unit or a separate pickup attached to the transom. The gauge measures pressure. You can disconnect the hose at the gauge and blow backwards to disloge whatever is clogging it.
how does a speedometer work on a boat? Speedometer (Pitot Tube Type) The pitot tube speedometer operates by air pressure changes in the hose and speedometer. Water is pushed through the pitot into the hose, compressing the air. Air pressure increases with boat speed, causing the gauge to indicate faster speeds.
Keeping this in consideration, how do I fix my boat speedometer?
