Creating Your Own Kayak Trolling Motor Mount

Building a kayak trolling motor mount yourself is totally achievable. You can save a good chunk of cash compared to buying a commercial one. Plus, there’s a great feeling of accomplishment that comes with using something you made. We’ve found that a sturdy DIY mount can be just as reliable as its store-bought cousins.

Essential Considerations Before You Build

Before you grab your tools, let’s think about what makes a good trolling motor mount. It needs to be strong enough to handle the motor’s thrust. It also needs to be stable so it doesn’t wobble or threaten your kayak’s balance. Think about where you’ll place it and how it will attach to your kayak.

Choosing the Right Location on Your Kayak

Where you mount the motor really matters. Most people find the stern (back) of the kayak to be the best spot. This keeps the motor out of your way while you’re paddling or fishing. It also helps with weight distribution. Some kayaks have pre-made mounting plates, which are a huge bonus. If yours doesn’t, you’ll need to create a solid mounting surface.

Understanding Your Kayak’s Material

Your kayak’s construction plays a role. Is it plastic (like polyethylene), composite, or inflatable? Plastic kayaks are common and generally easy to work with. You can often drill into them or use specialized hardware. Composites might require more care. For inflatables, you’ll need a special type of mount designed for soft surfaces, often using air pressure or specific adhesives. We found that understanding your kayak’s material helps prevent damage.

Common DIY Mount Design Options

There are a few popular ways to build your own mount. Each has its pros and cons. Let’s look at some of the most straightforward designs that many DIYers have success with.

The Transom Mount Style

This is perhaps the simplest design. It mimics a small boat’s transom. You’ll typically use a piece of sturdy lumber, like a 2×6 or 2×8. This wood is then bolted or clamped to the stern of your kayak. The trolling motor clamps directly onto this wooden board. It’s a no-fuss method that works well for many kayaks.

Materials for a Basic Transom Mount

For this style, you’ll need:

• A strong piece of wood (e.g., treated 2×6 or 2×8, about 12-18 inches long)
• Bolts, washers, and nuts (stainless steel is best to prevent rust)
• Optional: U-bolts or C-clamps for attaching the wood to your kayak
• Optional: Screws to attach a small backing plate to the wood

The Rail-Mounted System

If your kayak has existing accessory rails (like YakAttack or RAILBLADE), you’re in luck! You can build a mount that attaches to these rails. This often involves using rail-mount adapters and some aluminum or strong plastic to create a platform. This type of mount is often adjustable and can be repositioned easily.

Benefits of Using Kayak Rails

Using rails means you don’t have to drill holes into your kayak hull. This is a big plus for maintaining your kayak’s integrity. Many manufacturers offer specific adapters that work with their rail systems. We found that this method offers a clean look and good flexibility.

Custom Platform Mounts

For those feeling a bit more ambitious, a custom platform can be built. This might involve cutting a piece of durable plastic (like StarBoard) or marine-grade plywood. This platform can then be securely fastened to your kayak’s deck or stern using bolts and sealant. This offers a very customizable and robust solution.

Step-by-Step: Building a Simple Transom Mount

Let’s walk through building that basic transom mount. It’s a popular choice for its ease and affordability.

Step 1: Prepare Your Wood Board

Get your piece of wood. Cut it to the desired length, usually around 12 to 18 inches. You want it wide enough to securely clamp your trolling motor. Sand down any rough edges. You might want to paint or seal the wood to protect it from water damage, especially if it’s not pressure-treated.

Step 2: Attach Mounting Hardware

Decide how you’ll attach this board to your kayak.

1. Bolting through the kayak: If you’re comfortable drilling through your kayak’s stern, drill holes through the wood board and the kayak. Use large washers on both sides to distribute the pressure. Stainless steel bolts are a must.
2. Using U-bolts or C-clamps: Alternatively, you can use U-bolts or heavy-duty C-clamps that wrap around the kayak’s stern or a scupper hole (if applicable). Attach the wood board to these. This avoids drilling into the hull itself. We found this method is preferred by many paddlers.

Step 3: Mount the Trolling Motor

Once the wood board is securely attached to your kayak, you can clamp your trolling motor onto it. Position the motor so it hangs off the stern. Tighten the motor’s clamp securely. Ensure it’s straight and doesn’t wobble. It’s wise to double-check the clamp’s tightness before you head out.

Tips for a Secure and Stable Mount

A wobbly mount is no good. Here are some tips to make yours as stable as possible. Many experts suggest using backing plates where you bolt hardware through your kayak. This spreads the load and prevents the bolts from pulling through the hull material. For wood mounts, consider adding a thin layer of marine sealant around any drilled holes to prevent water intrusion. Research from boat builders often highlights the importance of proper fastening techniques (Naval Systems Engineering).

Reinforce Your Mounting Points

If you’re drilling, use large, thick washers on both sides of the bolt. This distributes the stress over a wider area. For very heavy motors or rough water, consider using backing plates made of aluminum or a sturdy plastic. These add extra strength. Many kayak anglers also add a small piece of starboard or plywood to the inside of the kayak where the bolts come through for added reinforcement.

Check for Movement

After installation, give the mount and motor a good shake. Does anything feel loose? Are there creaks or groans? Take your kayak to shallow water for a test run. Paddle around slowly, then engage the motor at low speed. Watch and listen for any signs of instability. Small adjustments can make a big difference.

Materials Comparison for Mounts

When choosing materials, consider durability and weight. Here’s a quick look:

Material	Pros	Cons
Treated Lumber (e.g., 2×6)	Inexpensive, easy to cut, readily available	Can be heavy, may warp or rot over time if not sealed well
Marine-Grade Plywood	Strong, relatively stable, takes sealant well	Can be more expensive than lumber, still susceptible to water damage
StarBoard / HDPE Plastic	Very durable, waterproof, won’t rot or warp, easy to clean	More expensive, can be harder to cut and drill than wood
Aluminum Angle/Flat Stock	Lightweight, very strong, corrosion-resistant	Can be more complex to fabricate, may require specialized tools

Frequently Asked Questions

What’s the best type of wood for a DIY transom mount?

For a transom mount, treated lumber like a 2×6 or 2×8 is a great choice. It’s durable enough to handle the motor’s stress and readily available. Ensure you seal it well with waterproof paint or sealant to protect it from constant moisture.

Can I use a trolling motor on an inflatable kayak?

Yes, but you’ll need a specialized mount designed for inflatables. These mounts often use air pressure or specific attachment methods that won’t damage the kayak’s material. Standard wooden or bolted-on mounts are generally not suitable for inflatables.

How do I prevent my mount from damaging my kayak?

Always use large washers on both sides of any bolts going through your kayak hull. For extra protection, consider adding backing plates made of sturdy plastic or metal. If you’re using clamps, ensure they have rubber or soft padding to avoid scratching or denting the kayak.

Is a rail-mounted system easier than a transom mount?

If your kayak already has accessory rails, a rail-mounted system can be much easier and quicker to install. It often requires fewer tools and avoids drilling holes into your kayak. Transom mounts might require more drilling and hardware, but they are still quite straightforward.

How tight should I clamp my trolling motor to the mount?

You want the trolling motor clamp to be securely tightened so the motor doesn’t shift or wobble during use. However, don’t overtighten to the point where you might damage the motor’s clamp or the mount itself. A snug fit that prevents any movement is ideal.
