Installing a jack plate for kicker motor mounting can honestly change the way your boat handles, especially if you're tired of your trolling motor dragging in the water when you're trying to get on a plane. It's one of those upgrades that sounds technical and maybe a bit unnecessary at first, but once you've got it dialed in, you'll wonder how you ever managed without it. Most of us just bolt our kickers directly to the transom or use a standard fixed bracket, but that often leaves the motor sitting at a height that isn't quite right for every situation.
When you're out on the water, whether you're salmon fishing in the Pacific Northwest or just trying to navigate a shallow bay, the depth of your kicker motor matters. A jack plate gives you the ability to move that motor up and down, which is a total game-changer for performance. Let's dive into why these things are so useful and what you should look for before you start drilling holes in your boat.
Why You Probably Need One
The main reason anyone looks for a jack plate for kicker motor use is usually because of a clearance issue. If you have a deep-V hull or a boat with a high transom, a standard long-shaft kicker might still sit too high to get a good bite in the water. Conversely, on some boats, the kicker sits so low that even when it's tilted up, the lower unit is still catching spray or dragging while you're running your main engine at full throttle.
That drag isn't just annoying; it's hard on the motor and it kills your fuel economy. By adding a jack plate, you're essentially giving yourself a vertical adjustment track. You can drop the motor deep when you need that thrust to hold a specific trolling speed against a heavy current, and you can jack it up high when you're cruising so it stays completely clear of the wake. It's all about finding that "sweet spot" that a fixed bracket just can't offer.
Manual vs. Hydraulic Options
When you start shopping, you're going to see two main types: manual and hydraulic. Now, I'll be the first to tell you that hydraulic is the dream. Being able to push a button at the helm and watch your kicker slide up and down is incredibly convenient. However, it's also pricey and adds more complexity (and weight) to your transom.
For most people, a manual jack plate for kicker motor setups is more than enough. You usually set it once or twice a season depending on how your boat is loaded, and then you leave it alone. Manual plates are generally lighter, which is a big deal when you're already hanging a heavy four-stroke kicker off the back of your boat alongside a massive main engine. You don't want to throw off your boat's center of gravity any more than you have to.
Getting the Setback Right
One thing people often overlook is "setback." This refers to how far the jack plate pushes the motor away from the transom. A little bit of setback is actually a good thing. It puts the kicker in "cleaner" water, away from the turbulence right against the hull.
But don't go overboard. Too much setback acts like a lever, putting extra stress on your transom. If you've got a smaller boat, keep the setback minimal. You just want enough room so the kicker can tilt forward without hitting the top of the transom or interfering with your main motor's steering linkage. I've seen guys install plates with 6 or 8 inches of setback on a small aluminum boat, and suddenly the bow is pointing at the sky every time they try to take off. Balance is everything.
The Installation Headache (And How to Avoid It)
I won't lie to you—drilling into your transom is always a bit nerve-wracking. The key to a solid jack plate for kicker motor installation is all in the prep work. You want to make sure you're using high-quality, marine-grade stainless steel hardware. Don't grab the cheap bolts from the local big-box store; they'll be a rusted mess within a month of hitting salt water.
Also, sealant is your best friend. You want to go heavy on something like 3M 5200 or a similar permanent marine adhesive/sealant. Slather it on the bolts and inside the holes to make sure no water ever finds its way into your transom core. If you've got a wood-core transom, this is even more critical. Rot is the silent killer of good boats, and it almost always starts at a poorly sealed bolt hole.
Checking for Clearance
Before you tighten everything down, do a dry fit. Mount the plate, hang the motor (if you can safely), and go through the full range of motion. Turn the kicker all the way to the left and right. Tilt it all the way up. You'd be surprised how often a kicker looks fine until you try to turn it, and then you realize the cowling is going to smash into your main motor's hydraulic steering lines. It's much easier to move the plate an inch to the side now than it is to fill holes and redrill later.
Performance Benefits on the Water
Once the jack plate for kicker motor is installed and you're out on the lake, the benefits become pretty obvious. If you're trolling for walleye and the wind picks up, you can lower the motor to get better traction in the water. This prevents the prop from "ventilating" (sucking air) when the back of the boat bounces over waves.
On the flip side, if you're running in shallow flats, being able to jack that motor up a few inches might be the difference between getting back to the dock and spinning a prop hub on a rock. It gives you a level of control that a fixed mount simply can't match.
Maintenance Is Still a Thing
Even though a jack plate is a fairly simple piece of metal, it still needs some love. If you're in salt water, you need to rinse it thoroughly after every trip. The sliding tracks on a manual plate can get "salted up" and seize if you don't keep them clean. I usually hit mine with a bit of marine grease or a dry PTFE lubricant once a month just to keep things moving smoothly.
If you went the hydraulic route, you've got to keep an eye on the fluid levels and the condition of the hoses. The last thing you want is a hydraulic leak in the middle of a fishing trip, leaving your kicker stuck in the "down" position while you're trying to run home in a heavy chop.
Is It Worth the Money?
You might be looking at the price tags and wondering if a jack plate for kicker motor is really worth the investment. If you're a casual boater who only uses the kicker once a year as an emergency backup, maybe not. But if you're a serious angler who spends hours trolling, it's worth every penny.
It's about more than just height; it's about protecting your investment. Keeping that kicker out of the saltwater spray and ensuring it's running at the optimal depth saves wear and tear on the engine. Plus, the improved boat handling and fuel efficiency are nice perks that add up over time.
Final Thoughts on Choosing a Plate
When you're finally ready to buy, don't just go for the cheapest one you find online. Look for plates specifically designed for small engines. Some of the jack plates meant for 300hp outboards are way too heavy and bulky for a 10hp kicker. You want something sleek, sturdy, and made from high-grade aluminum.
At the end of the day, a jack plate for kicker motor setups is about making your time on the water easier. Boating is supposed to be fun, not a constant struggle with equipment that doesn't quite fit right. Get the plate, spend an afternoon installing it correctly, and you'll notice the difference the very next time you hit the throttle. It's one of those small changes that yields big results for your boat's overall performance.
