Readers ask: Can I Use An Automotive Coil In A Boat?

Can automotive parts be used on a boat?

Car parts are for cars. Boat parts are for boats. Because if you buy an automotive alternator or any electrical appliance that’s not ignition-protected, you run the risk of blowing up your boat.

Are outboard ignition coils interchangeable?

Yes, the coils are interchangeable.

Are ignition coils car specific?

A modern passenger automobile may use one ignition coil for each engine cylinder (or pair of cylinders), eliminating fault-prone spark plug cables and a distributor to route the high voltage pulses. Ignition systems are not required for diesel engines which rely on compression to ignite the fuel/air mixture.

Do boats have ignition coils?

The coil is a critical part of an outboard engine’s ignition system. A coil is composed of a primary and a secondary circuit. If your outboard motor will not fire or runs hard — chugs and lurches — test the resistance of the coil using a voltmeter. The values given by a volt meter are in OHMS.

What is the problem with using your boat’s engine to drive it onto a trailer?

NOTE – While many people drive the boat onto the trailer, it isn’t advised. Using the engine to assist trailering erodes the ramp bed, can lead to debris being sucked into the engine, and can cause an accident! Make sure you drain all water from the boat – the bilge, the live well, the trailer lights, etc.

Can you use a car starter in a boat?

The starter for a car looks exactly the same as the one you just removed from your marine engine. Don’t be fooled by the fact that an automotive starter will bolt on to your marine engine. A marine approved starter has better seals and gaskets to keep water out. It also contains more corrosive resistant materials.

How do you tell if a coil is bad on an outboard?

Bad Coil Symptoms in an Outboard Motor

  1. Cracked Body. The coil on your outboard is a sealed unit.
  2. Hard Starting. If the coil is weak or damaged it will produce less spark energy than it is designed to.
  3. Engine Misfires.
  4. No Spark at Spark Plug Gap.

Can I use different ignition coil?

You can of course change just one coil. However, as a mechanic I’ve seen it so many times, when one coil fails another isn’t too far behind. If your coils are easy to access, replacing them as they fail is OK, apart from the inconvenience. It is possible to drive a car with a faulty coil but it isn’t advised.

What are the symptoms of a bad stator on an outboard?

The engine will lose spark on one or all of those cylinders. Making the engine run very poorly. This is why you can have a bad stator, but the engine will still run, just very poorly.

How often should ignition coils be changed?

The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.

What’s the difference between a coil pack and ignition coil?

The ignition coil is a device which is capable of generating a high voltage pulse which goes to the spark plug. Coil pack refers to the set of coils used in the engine which do not run a distributor. Each coil will supply power to the individual spark plug or a set of spark plugs.

What causes multiple ignition coils to fail?

When it comes to an ignition coil failure there are only three things that come to my mind; 1.) something is causing the ignition coil to work too hard; 2.) something is causing the ignition coil to be turned on too long resulting in overheating; or 3.) the ignition coil has worn out from a long life.

What happens if coil pack goes bad?

Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what’s commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.

How do I know if my boat spark plugs are bad?

Signs that your boat’s spark plugs are failing include:

  1. Trouble starting the engine.
  2. Engine hesitating or cutting out.
  3. Loss of engine power.
  4. Decreased acceleration.

What is the resistance of an ignition coil?

Most ignition coils should have a primary resistance falling somewhere between 0.4 and 2 ohms; however, refer to your manufacturer’s specifications for the correct reading. If a reading of zero is displayed, that signifies that the ignition coil has shorted internally in the primary windings and needs to be replaced.
