A tachometer is a useful tool to have in a boat. It tells you all sorts of information, such as whether the motor has started or stalled, and whether the prop is right for your boat. Tachometers work by counting the number of pulses or cycles the outboard has to get the correct reading. This is done by counting the number of poles on the charge coil as the fly wheel rotates.

What You'll Learn
- Tachometers count pulses to measure rotations
- Tachometers can be installed by wiring up the power and selecting the number of pulses
- Tachometers are more accurate than GPS for measuring boat speed
- Tachometers are useful for finding the right prop
- Tachometers can tell you if your motor has started or stalled
Tachometers count pulses to measure rotations
For example, if you have an outboard with six poles, you'll get six pulses per rotation. So, you select that on the dial with a screwdriver. The tachometer then counts those six pulses and when it gets to six, it knows it's done one rotation.
A tachometer is a really useful thing to have on a boat. It tells you all sorts of information like whether the motor has started or stalled, and whether the prop is right for your boat. It's a good instrument to help you find the right prop and to check if it's cavitating or if the bushing is failing.
A tachometer is just a display of the rpm to get you to a certain speed. When trolling for fish, about 1400rpm gives about 6 knots, which works perfectly. You can control the throttle by hand and make adjustments based on boat speed, not engine speed.

Tachometers can be installed by wiring up the power and selecting the number of pulses
The tachometer will tell you all sorts of information, such as whether the motor has started or stalled, and whether the prop is right for your boat. You can also use it to find out if the prop is cavitating or if the bushing is failing.
To install a tachometer, you will need to refer to the instructions for your brand of outboard, which will tell you how many poles your outboard has. You then need to select this on the dial with a screwdriver. You will also need to know the colour of the wire that is the signal wire.

Tachometers are more accurate than GPS for measuring boat speed
A tachometer can tell you all sorts of information, such as whether the motor has started or stalled, or whether the prop is right for your boat. It's a really good instrument to help you find the right prop and can also tell you if it's cavitating or if the bushing is failing.
When trolling for fish, about 1400rpm gives about 6 knots, which works perfectly. You can control the throttle by hand and make adjustments based on boat speed, not engine speed. If your boat is going too slow, you need more throttle, and if it's going too fast, you need less throttle. It's the knots you're interested in, not rpm.

Tachometers are useful for finding the right prop
When trolling for fish, about 1400rpm gives about 6 knots, which works perfectly. You can control the throttle by hand, but make adjustments based on boat speed, not engine speed. If your boat is going too slow, you need more throttle, and if it's going too fast, you need less throttle. It's the boat speed that matters, not the engine speed.

Tachometers can tell you if your motor has started or stalled
Tachometers are handy to have on boats as they can tell you if your motor has started or stalled. They work by counting the number of pulses or cycles the outboard has to get the correct reading. As the flywheel rotates, there's a certain number of poles on the charge coil, so it knows it's going to get six pulses per one rotation. It counts these pulses and when it gets to six, it knows it's done one rotation and then it translates that to the movement of the needle.
