This problem indicates that the outboard coil is not maintaining a steady voltage output. Maybe one day, the engine is giving smooth acceleration, but the next, it becomes rough. You could also notice that this occurs sporadically. In these cases, the engine might run erratically. Let’s say that the coil produces just enough voltage to start the engine and keep it running, but not enough to maintain the operation. And if it does, then it is going to be shaking or misfiring pretty badly. When the coil fails completely, you won’t get any more voltage to the plugs.īecause there will be a lack of energy to the plug, there will be no spark at the gap and your outboard motor will generally not start. Anytime this is noticed, you must replace the coil. This is a sign that the coil has gotten, hot, shorted, or overheated at some point in time. If you examine the coil and find it is cracked or looks melted. To run properly, the coil must remain intact and crack-free. Like everything that is on a boat engine, the coil inside your outboard is sealed component. This is another sign of possibly a bad coil, or missing spark on one cylinder. If the engine takes a little bit longer to fire up when turning the key and getting the engine to turn over. If you regularly foul the spark plugs, this is one indication that your boat is suffering from a weak spark. What you are left with is a weaker spark at the plug gap, which makes it more difficult to start the engine. When the coil becomes weakened and damaged, it is unable to produce the energy that it once did. Engine Experiences a Hard Starting Condition

If your coil does go bad, there are several symptoms you might notice. Symptoms of a Bad Coil on an Outboard Motor This spark then ignites the fuel, which keeps your motor running. This vital part is responsible for transforming the voltage from the battery into the volts needed to create a spark at the plugs. The marine coil works just like the component in your vehicle.
