Understanding Boat Speedometers
Before we delve into the problems associated with boat speedometers, it’s important to understand how they function. A boat speedometer primarily measures the speed of your vessel through water, providing crucial information for navigation.
Types of Boat Speedometers
There are two main types of speedometers used in boats:
- Mechanical Speedometers: These speedometers use a small paddle wheel located outside the hull. As the boat moves, water flows over the paddle wheel and turns it, which sends a signal back to the speedometer.
- Electronic Speedometers: These vehicles employ a transducer that reads water pressure or uses GPS to calculate speed. They offer more accurate readings and are less susceptible to mechanical wear.
Understanding the type of speedometer on your boat can help in diagnosing issues effectively.
Common Reasons Why Boat Speedometers Fail
There are several reasons why a boat speedometer may not function correctly. Below are some common problems:
