8 Things to Check Before Installing a Trolling Motor or Motor Mount

Planning to upgrade your boat with a trolling motor? Great choice! Whether you are passionate about fishing or just want smoother control over your boat, the right trolling motor can make your time on the water much more enjoyable.

But before you jump into the trolling motor installation, one key thing most boat owners overlook is properly setting up their trolling motor mount. If you do not have a solid mount, the motor won't work as it should.

In this article, we will discuss the top eight things you should check before installing a trolling motor or motor mount.

What to Ensure for a Successful Trolling Motor Installation

Trolling motors are an important component of any boat. The demand for these boats has surged over the past few years as recreational boating continues to grow in popularity, offering a peaceful and precise way to navigate lakes, rivers, and coastal waters.

As per reports, “The global recreational boating market was worth $29.0 billion in 2019 and is expected to grow to $35.4 billion by 2027” (Source). So before installing, paying attention to the checkpoints below ensures a safer, more efficient trolling motor installation and long-term performance on the water.

Here is what to consider:

1. Is Your Boat Compatible with a Trolling Motor Mount?

The first thing you need to do is check if your boat can support a trolling motor mount. Take a look at your boat’s bow (front) or transom (back) and ensure it’s sturdy and flat enough to support the mount.

If your boat is made of aluminum or fiberglass, that’s usually a good sign—but still double-check the thickness and strength of the area to make sure it’s better.

Also, make sure you choose the right mount type—bow mounts are best for serious anglers, while transom mounts are better for casual use or smaller boats. As per reports, “In 2024, the bow mount segment accounted for 64.8% of the market share.” (Source)

2. Do You Have the Right Trolling Motor for Your Boat Size?

Ensuring if your trolling motor is the right fit for your boat size and weight is the next key factor to consider. A motor that’s too weak won’t move your boat efficiently. One that’s too powerful can be harder to control.

Check the thrust rating of your trolling motor and compare it with your boat’s specifications. As per experts, “A 30-pound thrust motor is suitable for a 12-foot boat, while a 55-pound thrust motor is best for boats up to 21 feet in length.” Source

3. Where Will You Install Your Trolling Motor Mount?

Plan ahead. Think about where you want the motor to go. Whether it’s on the bow or the transom, the position of the motor largely affects its performance. A bow-mounted trolling motor gives you better control and precision, especially for fishing, while transom mounts are easier to install and ideal for smaller boats.

Measure carefully and visualize how the motor will deploy and stow. Make sure it won’t interfere with your fishing gear, seats, or other equipment.

4. Is the Mounting Surface Flat and Clean?

The surface where you’re installing the trolling motor mount must be flat and clean. Any unevenness can lead to a shaky motor, poor performance, or long-term damage to your boat or mount.

Clean off all the dirt, grease, or old adhesive before starting your installation process and if the surface isn't flat, you may need to use a leveling plate or shim to ensure a secure fit.

5. Do You Have the Right Tools and Hardware?

Having the right tools is nonnegotiable for a smooth trolling motor installation process. Here is a list of equipment you must have before embarking on this journey:

• Drill and bits (stainless steel recommended)

• Marine-grade bolts, nuts, and washers

• Marine sealant (to prevent water leaks)

• Screwdriver or wrench

• Measuring tape and pencil for marking

If your motor didn’t come with all the mounting hardware, make sure to get marine-grade replacements. Regular hardware tends to get rusty or fail in wet conditions.

6. Measure Twice, Drill Once

Once you've picked the right mount and collected all the necessary tools, carefully measure and mark where you’ll drill. A small error in positioning can throw off the whole trolling motor installation process. Double-check your measurements to ensure that the mount won’t interfere with hatches, storage lids, or the boat’s edge.

Also, make sure there’s enough clearance for the motor shaft and propeller to lower into the water properly.

7. Will You Be Using a Trolling Motor Tray?

Trolling motor trays are an excellent add-on that can make your motor setup cleaner and more comfortable. These trays allow your foot pedal to sit flush with the deck, reducing fatigue and giving you better control.

Check if your deck has enough room to install a trolling motor tray, and consider adding one during the installation process. It’s much easier to install everything at once than to go back and cut into the deck later.

8. Check Battery Placement and Wiring Length

Your trolling motor needs power, and that means you'll need to plan for battery placement strategically. Make sure your battery is located close enough to the mount, or be ready with extension cables.

Keep in mind that longer wiring can lead to voltage drop, which affects performance. It is best to use marine-grade wiring and connectors for the best durability and safety.

Final Thoughts

Installing a trolling motor or motor mount is not as hard as it seems. If you take the time to check everything in advance, like choosing the right location and planning for trolling motor trays and wiring, you can seamlessly install your trolling motor in no time.
