Alright, so here’s that casual, vendor-style blog post about mounting a trolling motor on an inflatable boat—totally real-sounding, no AI jargon, hits the mark. Trolling Motor
If you’ve ever spent a quiet morning fishing from an inflatable boat, you know the struggle of rowing against a lazy current or a light breeze. Hand-cranking gets old fast, right? I run a trolling motor supply company, and one of the most common questions I get from new customers is: “How do I actually mount this thing on my inflatable boat?” It’s not rocket science, but skip a step, and you’ll end up with a wobbly motor, a ruined transom, or worse—drifting way off your favorite spot. Let’s break this down like we’re chatting by the lake, no confusing jargon.
First, let’s get one thing straight: not every inflatable boat is built for a trolling motor. I see this mistake all the time—folks buy a cheap one-person inflatable dinghy, grab a 55-lb thrust motor, and wonder why the transom caves in. Inflatable boats come in two main types for motors: rigid transom and inflatable transom. Rigid transoms are the ones with a hard aluminum or fiberglass plate at the back—those are safe for trolling motors up to, like, 70 lbs thrust, depending on the transom’s thickness. Inflatable transoms (the ones that are just part of the air tube) are only good for small, light motors—max 30 lbs thrust, tops. If yours is a inflatable transom, don’t even bother with a heavy motor; it’ll pull the tube in and mess up the boat’s shape. That’s tip #1, don’t skip the motor-to-boat weight match.
Next, gear up. You don’t need a ton of stuff, but skimping here will make the job a headache. First, your trolling motor (duh—we’ve got a great selection, so hit us up if you’re still picking one out). Then, a mounting bracket designed specifically for inflatable boats—generic brackets for hard boats won’t cut it. Those have sharp edges that can puncture inflatable tubes, plus they don’t flex with the boat. Our brackets are made of marine-grade aluminum with rubber padding on the contact points, so they grip tight without scratching or popping a hole. You’ll also need: a drill (with a bit for your boat material—most inflatables are PVC or hypalon, so a sharp metal bit works), stainless steel bolts and lock nuts (rust is a killer on the water), a few large washers (rubber ones for the tube, metal ones for the bracket), and a tube of marine-grade adhesive (just in case you need extra grip on the tube). Oh, and a marker to pre-drill spots—no one wants to guess and mess up their boat.
Now, the step-by-step. Let’s start with prepping the boat. First, deflate the transom area a little. Not all the way—just enough to make the tube slightly soft where the bracket will sit. If you leave it fully inflated, the pressure will push against the bracket, and it won’t sit flat. Then, clean that area really well—use rubbing alcohol to get rid of any dirt, wax, or sunscreen. If there’s grime, the bracket won’t stick, and you’ll have a motor that shifts mid-troll. We always tell customers this: clean = happy mount.
Next, position the motor. This is key for performance. You want the motor shaft tilted so the prop is 12 to 18 inches below the waterline when the boat’s loaded (with gear, coolers, whatever you’re bringing). If the prop is too high, it’ll cavitate—suck air instead of water—and you’ll lose power. If it’s too low, it drags, makes noise, and slows you down. Also, make sure the motor is centered on the transom? Wait, no—wait, for inflatables, a little off-center is fine if you’re dealing with wind, but try to get it as close to the middle as possible so the boat tracks straight. Stand in the boat, step back, hold the motor up, and eyeball it. Don’t rush this—move the bracket around a few times until it feels right.
Once you’ve got the position marked, put the bracket on the boat, and mark the drill holes. Hold the bracket steady, and use your marker to draw the exact spots where the bolts will go. If you’re drilling into hypalon (the more heavy-duty inflatable material), we suggest making a small pilot hole first with a tiny bit, then going bigger. For PVC, you can go straight to the right size bit, but go slow—PVC can crack if you drill too fast. Now, drill the holes. If you hit a resistance check—maybe the air tube is thicker than you thought—slow down, and make sure you’re not drilling all the way through to the inside of the boat (that’s how you get a leak, oops).
Now, mount the bracket. Put the rubber washers on the bolts first, then slide them through the outside of the air tube, then add metal washers on the inside, then the bracket, then another washer, then the lock nut. Tighten the nuts evenly—don’t crank one all the way down before the others, that’ll warp the bracket. Go back and forth, tightening each a little at a time until it’s snug, but not so tight that you squish the tube flat. If you over-tighten, you’ll make a permanent indent in the air tube, which is bad news when you’re on rough water.
Once the bracket’s on, test it. Wiggle it back and forth—if it moves, you didn’t tighten the nuts enough, or you missed a washer. If it feels solid, attach the motor to the bracket. Most of our brackets have quick-release pins, so you can take the motor off when you’re done to save space. That’s a big plus for inflatable boat owners—extra storage is always nice. Tilt the motor up and down a few times to make sure the pivot works smoothly, and that the locking mechanism clicks into place.
Wait, one pro tip: add a tie-down strap. Even with a good bracket, if you hit a big wave or accidentally pull the motor up while moving, it could come loose. Run a heavy-duty marine strap from the top of the motor mount to a D-ring on the bow of the boat. That extra layer of security has saved so many of our customers from losing their motor mid-lake. No one wants to watch a $500 trolling motor float away, trust me.
Now, the fun part—testing it. Take your boat out in calm water, power it up, and go slow. See how the boat tracks. If it pulls to one side, adjust the motor’s position a little. If the prop cavitates, tilt the motor down a notch. If it drags, tilt it up. Don’t take it out in rough water on the first go—work out the kinks in a small, controlled area.
Let’s be real, mistakes happen. I’ve had customers come back with a dented transom or a motor that won’t stay in place, usually because they used the wrong bracket or skipped the cleaning step. Here’s what not to do: don’t use wood screws to mount the bracket—they’ll rust, and the sharp ends will poke through the tube. Don’t mount the motor too far forward on the transom—that makes the bow sit low, and you’ll take on water. Don’t use a motor that’s too powerful for your boat—we have a size chart on our site that matches boat length and weight to thrust, so use that.
Now, if you’re still unsure about mounting, that’s totally fine. A lot of customers ask if we offer installation help. We don’t send techs out, but we do have step-by-step videos on our Instagram and YouTube (go check ‘em out—we post real customer installs, not just fancy ads). Also, if you’re in the market for a trolling motor, our team can help you pick the right one for your inflatable boat—just reach out, we’re all boat guys here, we get it.
One last thing: maintenance. After each use, rinse the bracket and motor with fresh water to get rid of salt or algae. Tighten the nuts every few uses—vibration on the water can loosen them over time. If you’re storing the boat, take the motor off and wrap the bracket in a towel to keep it from scratching the air tube. That’ll make your setup last for years.
So yeah, mounting a trolling motor on an inflatable boat isn’t hard, but it pays to do it right. Skip the cheap brackets, match the motor to your boat, take your time drilling, and test it slow. If you’ve got questions, or you need a new motor or bracket, hit us up—we’re here to help you get on the water faster, no headaches.
