NGK Marine Spark Plugs: Everything You Need to Know
|
Welcome to our comprehensive guide on NGK marine spark plugs. Learn everything you need to know about marine spark plugs, including types, parts, and the importance of regular replacement. Explore our NGK marine spark plug charts to find the right spark plug for your boat's engine. Marine spark plugs are a critical component of your boat's engine. They are responsible for igniting the fuel-air mixture in the combustion chamber, which is what ultimately produces the power that drives your boat. View our outboard motor spark plugs charts below to find the right spark plug for your motor: |
Types of NGK Marine Spark Plugs
NGK marine spark plugs come in a variety of types, including:
- Standard spark plugs: These are the most common type of marine spark plug. They are made with a copper core and a nickel alloy shell.
- Platinum spark plugs: These spark plugs have a platinum tip, which makes them more durable and resistant to corrosion.
- Iridium spark plugs: These spark plugs have an iridium tip, which makes them even more durable and resistant to corrosion.
Parts of a Spark Plug

A spark plug is a relatively simple device, but it is made up of several important parts:The Importance of Replacing Your Spark Plugs
Spark plugs wear out over time, and they need to be replaced regularly. The recommended replacement interval for marine spark plugs is typically every 100 hours or 24 months. However, if you operate your boat in harsh conditions, you may need to replace your spark plugs more often.
Symptoms of Bad Spark Plugs
There are a few signs that your spark plugs may be bad, including:
- Engine misfires
- Poor fuel economy
- Rough idle
- Engine hesitation
- Black smoke from the exhaust
