Product Evaluation: Livorsi Marine GPS Speedometer

Installation is easier than most standard gauges, and the Livorsi GPS is a perfect replacement for standard speedometers.

The most common installation is a simple swap from the pitot-actuated speedometer to the GPS unit. The installation process is very straightforward, with only three main connections to make – gauge power and lighting, receiver connection, and electronic recall connection. It should be noted that there are two types of connections available for the receiver. The first type uses eyelet connectors that are attached to studs on the gauge itself. This is beneficial for custom installations where resizing the receiver cable is necessary. The second type is a simple plug connector that requires no tools to install, and it just snaps in place. For this installation, we are using the eyelet-type connector, since we’ll want to cut the receiver wires to match our installation perfectly.

Once the gauge is installed, select a location for the receiver antenna. It is recommended that the antenna be mounted above the deck, or in a location where it is unobstructed. In most cases, however, the receiver will function if it is mounted below the deck of your boat. If you choose to mount the receiver in this location, you should test it by temporarily mounting the unit in your desired location before drilling any mounting holes. In our installation, we found that the Livorsi GPS receiver had no problems functioning under the deck of our boat.


Left to right:  1. Cutting the gauge bracket to fit our angled bezel.  2. Make certain the gauge is perfectly centered before cutting brackets or wires.  3. Recall switch plug just snaps into place. 4. Receiver antenna leads connected.

The final step in your installation is to choose a location for your recall toggle switch, which connects to the head unit via simple a plug-in terminal. The switch is weatherproof, so you can mount it in virtually any location, and the recall feature comes in very handy during engine tuning.

Even at over 120 MPH, the Livorsi GPS maintained perfect accuracy with no needle jump whatsoever.  160 MPH version shown.

Typical of Livorsi Marine, gauge and system quality are top notch. Unlike other systems, the Livorsi gauge is designed to not only perform accurately, but withstand the rigors of the marine environment. We tested our GPS unit at over 120 MPH, and accuracy is spot on.  Our unit experienced no needle jump at all, allowing for quick glances at the gauge for an accurate reading.

The Livorsi GPS also refreshes much faster than typical handheld units, providing more accurate acceleration feedback. Livorsi Marine also offers a military-grade dedicated and portable GPS testing unit designed to measure critical changes in speed very quickly.  This particular unit is housed in a weatherproof Pelican case for maximum protection.

It's difficult to find a reason why you would not upgrade your speedometer to GPS technology.  Livorsi Marine offers a kit that is suitable for every application, from pleasure boating to professional racing.  Although handheld units are convenient at times, they simply can't match the satellite acquiring ability and fast refresh of these dedicated gauges.
