A propane outboard motor is an alternative to a standard gasoline powered outboard motor. Using propane offers some advantages, environmentally and economically. Propane burns 50 times cleaner than gas, and is domestically produced. Also, a propane outboard motor will generally start more easily that a gas one due to the fuel being pressurized. Propane motors are very easy to refuel and there are no issues with water in your fuel.

Choosing a propane outboard motor is an important investment for a boat owner.  Sticker shock is common for a new propane outboard motor, as prices are typically between $400-$1000.  While the price may seem high, a good propane motor is well worth the cost.  A propane outboard motor is not an essential piece of equipment on a boat, it is good for the environment and a healthier alternative to gasoline motors.

Our buying guide reviews the best propane outboard motors on the market so you can choose the right one for your needs. Here are some features to look out for which commonly occur when looking at propane outboard motors.

Efficiency Features

Propane outboard motors have features which make them easier to use and more efficient. In order to preserve the clutch, a start-in-gear feature may be utilized. This stops the prop from rotating when the motor is idling, therefore protecting the clutch from unnecessary damage. Another feature you may come across is CDI ignition system which makes starting the motor easy. Lastly, propane motors should have built in air cooling systems to ensure they run to their maximum potential.


There are a number of materials commonly used in propane outboard motors. The motors ideally need to be lightweight because of the type of boat they will be on. Aluminum alloy is used for its strength and durability, as well as engineered plastic which is lightweight yet fairly strong.


Windlasses are made of corrosion-resistant materials because they are installed at the bow of the boat where they have high exposure to sun and sea spray.  Common materials include stainless steel, aluminum, and plastic.  Be sure to buy a windlass that is made of high-quality materials for a long service life.  Stainless steel is the strongest and best choice for long term use.


360 steering control is a great feature on a propane outboard motor. This feature allows you to reverse easily, perfect for getting out of those tricky situation that may arise on the water.
