Upgrading Your Ulterra Trolling Motor: GPS, Remote, and When to Walk Away

Is the Ulterra GPS Upgrade Worth It? Three Scenarios, One Honest Answer

If you manage purchasing for a marine dealership, a fishing guide service, or a fleet maintenance operation, you've probably seen the question come up: "Should I get the Ulterra Advanced GPS Upgrade Kit?" Or maybe it's the other way: "My Stow/Deploy stopped working—is it the remote or the motor?"

There's no universal answer. Period. The right call depends on what you're working with—and I've learned that the hard way over about 80-odd orders I've processed since 2022 for our small fleet.

So let's break it into three common scenarios. I'll give you my honest take for each, and then help you figure out which one matches your situation.

The Three Flavors of 'Should I Upgrade?'

In my experience, most inquiries fall into one of three buckets:

1. The Retrofit Project – You have an older Ulterra (pre-2019) and want the latest GPS/i-Pilot Link features.
2. The 'What's Broken?' Diagnosis – Your remote is acting up, the motor won't deploy, and you're trying to decide if it's a fix or a full swap.
3. The 'New Build' Decision – You're spec'ing out a new boat or rig and wondering if the upgrade kit is worth the premium over the base model.

Each one has a different answer. Let's walk through them.

Scenario A: The Retrofit Project (Older Ulterra → New GPS)

If you're sitting on a 2017 or 2018 Ulterra that works fine mechanically but lacks the fancy GPS-based features—Spot-Lock, jog controls, the i-Pilot Link ecosystem—the Advanced GPS Upgrade Kit is compelling.

From my perspective, this is the sweet spot for the upgrade. I've processed orders for these kits and seen the results. The install is straightforward if you're comfortable with basic wiring (remove the old control board, plug in the new one, re-pair the remote). According to Minn Kota's own literature, the kit is compatible with most Ulterra models (check the serial number against their compatibility chart—I've seen one slip-up where a post-2020 model needed a different harness).

What I'd recommend: If the motor itself is in good shape—no corrosion, no intermittent stow/deploy failures—go for it. The upgrade cost is roughly $250-400, which is less than half of a new Ulterra. You get the full i-Pilot Link functionality. Simple.

But—and this is critical—if the motor has any history of deployment issues (sticking, slow retraction, error codes), I'd pause. The upgrade kit doesn't fix mechanical problems. It only upgrades the electronics. We had a customer who retrofitted a motor with a sticky drive shaft. The new GPS worked great, but the motor still wouldn't stow reliably. They ended up replacing the whole unit six months later. That's $400 down the drain.

Oh, and one more thing: the upgrade kit requires the current software version to be compatible. If your motor is really old (pre-2015), you might not be able to update the firmware. I learned that one the hard way on a 2014 model. Should mention: check the firmware version before ordering—Minn Kota's support line is actually helpful for this, call them first.

Scenario B: The 'What's Broken?' Diagnosis (Remote vs. Motor)

This is the one I see most often in the admin chair: someone calls up and says, "My Ulterra won't deploy from the remote. Is it a bad remote, or is the motor fried?"

The honest answer? It's usually not the motor. The i-Pilot remote is a fairly complex piece of electronics—rechargeable battery, touchscreen, wireless pairing. I'd say 7 out of 10 times the issue is the remote, not the motor head.

Here's a quick diagnostic checklist I've stolen from our service tech (his name's Eddie, and he's been fixing trolling motors for 15 years):

1. Check the remote battery. Sounds dumb, but we had a customer order a whole new remote kit because his didn't power on. Turned out the battery was dead and the charging cable was frayed. A $15 cable later, problem solved.
2. Try the foot pedal. If the motor deploys with the pedal but not the remote, it's a remote or pairing issue. If neither works, it's more likely the motor control board.
3. Look at the Bluetooth pairing. The remote sometimes loses its pairing after a firmware update. Re-pairing is simple (I can walk you through it, but Minn Kota's manual is actually clear for once).

What I'd recommend: If you're in this scenario, don't order the full GPS upgrade kit yet. First, try a new i-Pilot remote (about $100-150) or just a charging cable. We've had good luck with replacement remotes from the OEM. That said—I should be honest—I've only worked with the Minn Kota branded remotes, not aftermarket ones. If you're looking at a third-party remote, your experience might differ.

If it turns out to be the motor's control board, then you're looking at $200-350 for the board plus labor. At that point, the math gets fuzzy. A new Ulterra is $1,200-1,800 depending on shaft length and voltage. If you're paying $350 to fix an 8-year-old motor... I'd start thinking about Scenario C.

Scenario C: The 'New Build' Decision (Should You Pay for the Upgrade?)

This is the one where I have a surprisingly strong opinion that might sound weird at first: Sometimes, the upgrade isn't worth it, and you should save your money for something else.

Controversial, right? The Ulterra Advanced GPS Upgrade Kit is a fantastic add-on for serious anglers who use Spot-Lock heavily, chart trails, or integrate with Humminbird fish finders. If that's you, great. Buy it. It's worth every penny for the convenience alone—auto-stow/deploy plus GPS navigation is a killer combo.

But if you're a casual weekend fisherman who lives on a smaller lake and doesn't need GPS-guided trolling? The base Ulterra (or even a Terrova) might be overkill. And upgrading to the GPS kit when you don't use the features is just throwing money at a problem you don't have.

I'm going to use a weird analogy here: it's like buying an elaborate Halloween costume for a party you're not even sure you're attending. You see a great idea (Eddie Murphy's character from "The Nutty Professor"? Or maybe a crusty old fisherman costume?), you buy all the parts, and then the party gets canceled. You're left with a bunch of stuff you don't need.

What I mean is: don't upgrade for the sake of upgrading. Ask yourself: "What problem am I actually solving?" If the answer is "I want Spot-Lock for precise anchoring," then yes. If the answer is "I heard it's better," then maybe not.

Also—I should note—if you're running a saltwater boat, pay attention to the 'Riptide' models. The Ulterra and Riptide Ulterra are different animals. The Riptide has a sealed control board and corrosion-resistant components. The Advanced GPS Upgrade Kit for the standard Ulterra won't work on a Riptide. Don't ask how I know this. (Fine, I'll tell you: we ordered one without checking, and it sat in our warehouse for two weeks before we realized the mistake.)

How to Know Which Scenario You're In

Here's a quick checklist I use when I'm helping our internal team decide:

• If your motor is less than 3 years old and has no mechanical issues → You're in Scenario A. The upgrade kit is a good bet.
• If your motor won't deploy/stow but GPS worked before → You're in Scenario B. Start with the remote, not the motor.
• If you're buying new and you don't fish with GPS features → You're in Scenario C. Save the $400 and put it toward a better transducer or a nice cooler. Seriously.
• If your motor is old (5+ years) and has multiple issues → Honestly, you're probably looking at a replacement. The upgrade kit will be a band-aid, not a cure.

One last thought: I've been managing this stuff since 2020, and I still make mistakes. The biggest one was assuming a "standard" Ulterra was the same across years. It's not. The control boards changed in 2020, the i-Pilot Link version changed in 2021, and the Bluetooth protocol changed in 2023. If you're not 100% sure about compatibility, call Minn Kota support with your serial number. It'll save you a headache—and a return shipping fee.

My experience is based on about 60-80 orders for trolling motor parts and upgrades, mostly for mid-range freshwater boats. If you're working with a full-scale commercial saltwater operation, your experience might differ. So take my advice, but apply it to your specific situation.

Simple as that.
