A successful day of fishing often depends on stealth. The quiet approach, the subtle cast, and the ability to hold your position without spooking the fish are all part of the art. While traditional outboard engines get you to your fishing spot quickly, they aren't designed for the finesse required for trolling or navigating shallow waters quietly. This is where a trolling motor becomes an angler's best friend.
For boat owners who want to maintain a clean, uncluttered deck, engine mounted electric trolling motors offer a brilliant solution. These motors provide the quiet power needed for precision boat control without taking up valuable space on the bow or transom. If you're looking to enhance your fishing experience with a powerful, space-saving tool, this guide will walk you through everything you need to know. We'll cover what they are, their key benefits, and how to choose the right one for your boat.
An engine mounted electric trolling motor is a compact, self-contained unit that attaches directly to the cavitation plate of your boat's main outboard or inboard/outboard (I/O) engine. Unlike bow-mount or transom-mount motors that require their own dedicated space, these motors integrate seamlessly with your existing propulsion system.
When you're ready to fish, you simply deploy the motor into the water. It operates independently of your main engine, providing quiet, electric power for slow-speed maneuvering, trolling, and holding your boat's position over a fishing spot. When you're ready to move on, you can easily retract it out of the water, and it stays tucked away behind your main engine, creating no drag while you're cruising at high speeds.
Choosing an engine mounted trolling motor comes with several significant benefits, especially for anglers who value efficiency and a clean boat layout.
The most obvious advantage is the conservation of space. On many smaller to mid-sized fishing boats, deck and transom space is a precious commodity. Bow-mount motors can interfere with casting and anchoring, while transom-mount motors can get in the way of your swim platform or main engine. An engine-mounted unit keeps your deck completely clear, providing an unobstructed fishing platform. This minimalist approach is perfect for boaters who dislike clutter and want to maximize their usable space.
Like all electric trolling motors, engine-mounted versions operate almost silently. This allows you to approach fishing spots without disturbing the fish, which is a massive advantage in shallow or calm waters. They offer the precise speed control needed for trolling lures and baits at the perfect speed, an essential factor for attracting species like walleye, salmon, and trout.
When not in use, the motor is completely out of the way. It doesn't need to be removed and stowed, nor does it create an obstacle on deck. Because it's mounted on the cavitation plate, it sits out of the water when the boat is on plane, meaning there is zero drag. This ensures your boat's top speed and fuel efficiency are not compromised.
These motors are built to withstand the harsh marine environment. They are typically constructed from corrosion-resistant materials. Their mounting position on the cavitation plate also offers a degree of protection. The skeg of the main outboard engine often acts as a shield, protecting the trolling motor from underwater obstacles like rocks, logs, or sandbars.
Selecting the right model depends on your boat, your fishing style, and your specific needs. Here are the key factors to consider when making your choice.
Thrust, measured in pounds (lbs), is the single most important factor when choosing a trolling motor. It determines how much power the motor has to move your boat through the water. An underpowered motor will struggle against wind and current, while an overpowered one might be overkill and drain your battery faster than necessary.
A general rule of thumb is to have at least 2 pounds of thrust for every 100 pounds of your boat's fully loaded weight (including gear, fuel, and passengers).
★For smaller boats (under 3,000 lbs): A motor with 55-80 lbs of thrust is usually sufficient.
★For larger boats (3,000-5,000 lbs): You'll likely need a model with 80-112 lbs of thrust or more.
Always err on the side of more thrust if you frequently fish in strong currents, windy conditions, or offshore.
Engine mounted trolling motors come in 12V, 24V, or 36V systems. The voltage is directly related to the motor's thrust and runtime.
★12V Systems: Typically found on motors with up to 55 lbs of thrust. They require a single 12V deep-cycle marine battery. This is a good option for smaller boats and anglers with modest power needs.
★24V Systems: Used for motors in the 60-80 lb thrust range. They require two 12V batteries connected in series. They offer more power and longer run times than 12V systems.
★36V Systems: The most powerful option, powering motors with over 100 lbs of thrust. They require three 12V batteries and provide the best performance and longest endurance, making them ideal for large boats and serious anglers.
When planning your battery setup, remember to account for the space and weight of the batteries, as well as an onboard battery charger to keep them topped up.
How you control the motor is another crucial consideration. Engine-mounted units typically offer a few different control methods:
★Handheld Remote: Many modern motors come with a wireless handheld remote. This gives you the freedom to control speed and steering from anywhere on the boat. It's incredibly convenient, allowing you to focus on fishing rather than being tied to a tiller.
★Foot Pedal: While less common for engine-mounted units compared to bow-mounts, some models may offer a wired or wireless foot pedal. This allows for hands-free operation, which is a favorite among bass fishermen who need to cast and maneuver simultaneously.
★Tiller Handle: Some basic models might use a traditional tiller handle for control. This is a simple and reliable method, but it requires you to be at the transom to operate the motor.
Top-tier models from brands like Minn Kota and MotorGuide offer sophisticated GPS features that can revolutionize your fishing.
★Spot-Lock (or Anchor Mode): This feature uses GPS to hold your boat in a fixed position, automatically compensating for wind and current. It's like a virtual anchor, allowing you to stay on a hot spot without constantly adjusting your motor.
★Autopilot and Track Recording: You can set the motor to follow a specific compass heading (Autopilot) or record a path (a track) and have the motor automatically retrace it. This is perfect for trolling a specific depth contour or shoreline.
While these features add to the cost, they provide a level of boat control that was once unimaginable, freeing you up to focus entirely on fishing.
For the angler who demands performance, precision, and a clean, functional boat layout, an engine mounted electric trolling motor is an exceptional investment. By providing silent, powerful control without sacrificing an inch of deck space, these motors solve a problem that has challenged boaters for years. They blend seamlessly into your existing setup, ready to be deployed at a moment's notice to give you the stealthy edge needed to land more fish.
