Comforting purr…then nothing. Sound familiar?
Before you panic and think you're entire ignition system needs replacing, consider your options. The cause for your boat ignition breakdown could be simple. Energy supply can cause boat ignition failure.
First, check your battery. Make sure you have a solid ground connection. A loose cable could be the cause for your motor not turning.
If your battery is low and represents an ongoing problem, consider installing a secondary battery bank. This is particularly important with today’s modern engines where low battery voltage can keep the ignition system from functioning properly.
Or track energy usage with a metering device. Have energy in reserve to guarantee an ignition start.
Have you replaced your spark plugs lately? Fouled spark plugs could be the problem. This could explain why the boat engine stopped running and represents an easy fix. Replace with one of our long-lasting spark plugs from top brands.
Another common hidden problem is corrosion. If you’re a weekend boater, it’s easy to forget the simple things like cleaning the battery terminals. A wire brush and corrosion spray can work wonders. Inspect, clean and coat each exposed connection with a quality anti-corrosion product. Make it a habit.
Sometimes the simplest solution represents the likeliest answer to your ignition problem.
1) Has water run into the key switch and corroded it?
2) Is the kill switch loose in its fitting? On some boats, the engine won’t start if the safety lanyard is not installed properly. Mounting screws may need tightening.
3) Other motors have an ignition fuse which, when blown or missing, will disable the system.
4) Are you out of gas?!
Rule of thumb: check the basics first like wiring and connections (and fuel level). Then consider more expensive options like replacing the ignition power pack or ignition coil.
It pays to know how an ignition system works because it can cost you a ton on labor and diagnostics if you don’t.
