Can you use a freshwater motor in salt water?

You can use a fresh water motor in salt water but it will be prone to damage so is not recommended. If you do it, be sure to rinse off well.

Where there is a particular type of trolling motor that is suitable for use in the brackish, the fresh water motor also has the flexibility to perform well in the salty water, though that performance is limited to a particular extent. It is however, not highly recommended to use a fresh water motor in the more saline parts of the sea, as it’s parts are less protected against the cruelty brackish will subject it to. 

A trolling motor is primarily an electric motor who’s your best bud when it comes to going after fishes in the waters. It is attached to the bow or stern of your boat. It’s noiselessness is what makes it ideal to be used for fishing as that keeps the fish from being spooked away like they would be by any regular motor.


Protecting your fresh water motor after use in salt water 

If you have decided to go ahead with using your motor in salt water, this next part is crucial for you to read. There are a few protective methods that can make your motor a little friendly with the salt. The application of these depends entirely on how long you are planning on taking it for a spin in the sea. If it’s a quick in and out situation a thorough rinse will work well as a protective measure, but if you are deciding to shift your attention to the saline part of the waters for an extended period of time, you should consider selecting a more permanent solution. 

Installing sacrificial nodes 

These are like young soldiers protecting the borders, they lay down their lives to save the nation. They have the tendency to corrode away to keep the motor from rusting. After attaching these you should keep regular check on their status and replace them when needed.

Rinse off with fresh water 

After using the motor, spray it with fresh water. This will wash away any sediments that might have stuck in the internal parts and have been secretly conspiring to subjecting it to rust. 


Using paint

Get a little creative, use those bright colours that spark joy. Paint serves as a protective coat that will prevent the metal from rusting. You can use temporary paint when taking it for a dive and then return it back to the original state when done. Paint can be unreliable and can chip off. There can be a need to monitor it carefully. 

Don’t leave the boat submerged in water

Once your feet touch the shore you should carry your boat out of the water. Leaving it in there will expose it to the harm of salinity, which is why it is important that you at all costs do not abandon it in the water.  

Types of trolling motors 

Trolling motors are classified into fresh water and salt water motors. What sets them apart are their components. Salt water motors are constructed in a way that their parts remain protected against the salinity they will be exposed to. Salt water motor consists of sacrificial anode which is what guards the motor against the extremely corrosive effect salinity of the water can have on it, this is all thanks to the coating on the anode with a material that protects it from rusting. It adds to the performance of the motor and makes it long lasting. To further make them suitable for salt water use they have covered electrical connections and stainless steel hardware.

Which motor to choose? 

The type of trolling motor you need to choose depends mainly on where you are planning to carry out your favourite water sport activity. The type of water will be the judge of what kind of trolling motor you need. 

The decision to whether use your fresh water motor in salt water comes down to you. It is an easier option to buy a salt water motor. It will also be more reliable and will be less prone to damage, however if you are willing to spend some time putting the protective measures in effect you can also make use of your fresh water motor.
