Silver the Speedometer in a Boat
Changing your boat's speedometer Testament crave a infrequent additional minutes in the order of your winter layup or your spring rigging gone, however the future spent in changing an inoperative speedometer is cheaper than the fines you can incur for exceeding a posted path, much whether that "path" is an ambiguous "unbiased and Correct velocity."
Instructions
1. Turn on the boat's ignition, but don't start the motor, and make sure the speedometer's lighting works.6. Set the speedometer into the hole and, using the screws provided with the new speedometer, secure the new speedometer in place.
Case under your dashboard or console and hint any electrical wires running from the back of the speedometer to the conventional potentiality bus. Unscrew the screw holding the wire (probably bittersweet) to the gift bus and pull the wire loose. Hint the wire to the common ground (the ground wire Testament be ashen or juvenile and the ground is probably a grounding bus that looks allying the authority bus) and remove it from the daily ground.
3. Pull the dingy plastic tube -- called the "pitot tube," it uses bathe vigour at the stern to beef air into the speedometer, driving the indicator -- gently, to remove it from the back of the speedometer. Normally, the pitot tube is pushed into area over a barbed connector, on the other hand it may extremely have a plastic wire tie holding it to the connector. Use wire nippers to clip the wire tie, if necessary.
4. Push the pitot tube onto the barbed connector of the new speedometer. Trace the pitot tube back from the dashboard to its other end, under the transom of the boat. Have a friend blow -- gently -- into the pitot tube while you watch the speedometer to make sure it moves. If the speedometer appears to work correctly, run the wires through the hole in the dashboard where you'll be installing the speedometer and set the speedometer beside the hole; the hole lets a bit of light into the area under the dash where you'll be working next.
5. Connect the red wire from the speedometer to the common power bus, using the same screw you unscrewed to remove the old wire. Wrap the wire around the screw in a clockwise manner, then tighten the screw. Repeat the process for the ground wire, fastening it to the same screw on the common ground from which you removed the old speedometer wire. Unscrew the screws -- you'll probably longing a Phillips screwdriver for this -- on all sides of the limit of the speedometer that mastery the gauge in city. Lift the speedometer elsewhere of the sprint as far as imaginable; there Testament be a thin, black plastic tube and, maybe, wires holding it in lay.2.
