Need to get your boat's speedometer working again? This TOTMOX Pitot Tube is a simple, affordable fix. It's the part that mounts on the transom (the back of the boat) and uses water pressure to tell your speedometer how fast you're going. This one has a handy automatic kick-up feature – if you hit something underwater, it flips up to avoid damage, then snaps back into place. It's made of durable white plastic and is designed to provide stable water pressure for accurate readings up to 80 MPH. It should work with most standard pressure-driven speedometers (the kind with a hose connection). Just make sure it's compatible with your specific boat and gauge setup. Installation is usually pretty straightforward. A must-have replacement part to keep an eye on your speed while you're out on the water.
