Quick answer: The Mercury Avator 7.5e is a 750-watt electric outboard with roughly the thrust of a 3.5 HP gas portable. It shines as a silent trolling kicker, as a motor for small fishing boats and tenders, and as a clean sailboat auxiliary. It is not a main motor for anything bigger than a light 12-foot tinnie.

We sell gas outboards and we sell electric. We have no reason to oversell either one. So here is the straight version of the Mercury Avator 7.5e: it is very good at a narrow job, and a poor choice the moment you ask it to do something else.
The Avator 7.5e is Mercury's smallest electric outboard. It puts 750 watts at the prop, charges off a wall outlet, and runs nearly silent. For a Rice Lake angler easing along a weed line at first light, that silence is the whole point. For someone who needs to cover the lake all day on one boat, it is the wrong tool, and no amount of wanting will change that. This review stays on the honest line between those two.
What is the Mercury Avator 7.5e and who is it for?
The Avator 7.5e is the entry point in Mercury's electric Avator family. A brushless electric motor, a removable lithium-ion battery, a full-colour display on the tiller, and none of the gas, oil, fumes, or pull-start of a small two or four-stroke. Press a button, twist the grip, go.
A note on the number. Mercury rates the Avator by output power, kilowatts at the prop, and by equivalent thrust, not by a gasoline horsepower figure. In plain terms, the 7.5e pushes a boat about like a 3.5 HP gas portable would. We lean on that comparison because it is how people shop, but the spec that matters is 750 watts at the prop.
Three customers, and the Avator is the right call for all three. The Rice Lake angler who wants a silent kicker: trolling for walleye in 12 feet of water, you do not want exhaust in the boat or engine drone in the water, and the Avator lets the hull slide through good water without announcing itself. The sailboat owner who needs an auxiliary: clean, low-vibration thrust to get out of the slip and back, no two-stroke smell in the cockpit. And the tender or car-topper owner under 14 feet: a 9 to 12-foot tender behind a cottage cruiser is exactly its weight class, light and easy to charge off cottage power.

The Avator costs more the day you buy it. It earns that back three ways: no fuel, no annual oil change, and silence. It is still a niche pick. For most repower customers a gas portable is the right tool and the smaller cheque. For fishing, and for anyone who values quiet water, the Avator is worth every dollar of the difference.
What is the real range and battery life on Rice Lake?
Range is the whole conversation with an electric outboard, and brochure numbers are a starting point, not a promise. Wind, chop, boat weight, water temperature, throttle position: every one of them moves the answer.
We have run the Avator on customer boats around Rice Lake long enough to give you numbers you can plan around. At a slow troll, 1.5 to 2 mph, the speed that drags a worm harness for walleye, the 1 kWh battery holds 3 to 5 hours. That is a full fishing morning or a full evening. Push to half throttle for transit, 3 to 4 mph on a light boat, and you are looking at roughly 45 minutes. Wide open into a headwind, under an hour.
The tiller display shows battery percentage and estimated runtime against your current throttle, so you are never guessing. Most Avator owners add a second 1 kWh pack, running dual or carrying a spare, and the swap takes under a minute because the batteries latch in like a cordless-drill pack. Two batteries is effectively a full day of trolling. One more thing for early season: cold water in May pulls 10 to 20 percent off capacity, so keep the first trips short.
How does the Avator fit into a Mercury repower?
The Avator is rarely the whole repower. More often it is half of one: a gas main motor plus the Avator as a silent kicker.
The pairing we rig most on Rice Lake is a Mercury 90 HP FourStroke for getting between spots and an Avator 7.5e on a kicker bracket for working them. Two motors, two jobs. The 90 gets you there. The Avator keeps the boat quiet while you fish, no exhaust, no smell, no engine buzz through the deck on a weed line. If you are weighing a main-plus-kicker setup, our Mercury ProKicker and trolling guide lays out the options, with the Avator as one strong kicker beside Mercury's small gas portables.
What does the Mercury Avator 7.5e cost installed?
Installed pricing at Harris Boat Works runs by battery configuration:
- Avator 7.5e plus single 1 kWh battery plus mount: $4,500 to $5,200 CAD
- Avator 7.5e plus dual 1 kWh batteries plus mount: $5,500 to $6,500 CAD
Installation covers the kicker bracket if used, throttle wiring, charging setup, and a water test on Rice Lake. Pickup only at Gores Landing: no shipping, no delivery. The deposit is $200 for portable and small-HP motors, and financing is available on approved credit. Our Mercury repower cost guide breaks down the full motor families, and we keep spare battery packs in stock for anglers who want to double their day on the water without a run back to the dock.
What are the Avator's limitations?
An honest review owes you the limits. Three of them.
Range. The Avator is not a distance motor. Plan a full day of open-water crossings on one battery and you will run it flat. Carry a spare or charge at the dock. The honest Rice Lake figures: 3 to 4 miles flat out, 8 to 12 at half throttle, 20 to 25 if you treat it as the slow trolling tool it is built to be.
Cold. Electric motors shrug off cold better than gas does, but the battery does not. Expect 10 to 20 percent less runtime on early-season Rice Lake.
Scope. The 7.5e is small, and it cannot be wished into something bigger. It will not replace a gas main motor on a heavy 16 to 18-foot boat that needs to run all day. Buy it for the job it is built for, silent kicker, tender, sailboat auxiliary, light boat, and it becomes one of your favourite things on the water. Buy it for the wrong job and you will be disappointed, and that is not the motor's fault.
What we see at HBW
Every happy Avator owner we have rigged bought it for the right reason. They wanted a silent kicker, or a clean little motor for a tender, and that is exactly what they got. The disappointed electric-outboard stories we hear, almost always a motor bought somewhere else, are the same story every time: someone asked a small electric to do a big gas motor's day. Match it to the task and the Avator is quiet, simple, and close to maintenance-free. We rig it, water-test it on Rice Lake, and hand it back at Gores Landing.
Frequently Asked Questions
Is the Mercury Avator 7.5e powerful enough as a main motor?
Only on very small boats: tenders, dinghies, small sailboats, and 12-foot tinnies with light loads. For most fishing boats and any pontoon it works as a kicker, not a main motor.
How long does the Mercury Avator 7.5e battery last?
About 45 minutes at half throttle on the standard 1 kWh pack, and 3 to 5 hours at a slow trolling speed of 1.5 to 2 mph. Dual-battery setups roughly double that runtime. At wide-open throttle, expect under an hour.
Can I use the Avator for bass and walleye fishing on Rice Lake?
Yes, and that is one of its best uses. Silent thrust at slow speed makes it ideal for finesse fishing in shallow weed lines. Pair it with a gas main motor for travel between spots.
How much does the Avator 7.5e cost installed?
Including the motor, battery, and mounting, expect roughly $4,500 to $6,500 CAD installed at Harris Boat Works, depending on battery configuration. Pickup only at Gores Landing.
What charges the Avator battery?
A standard 120V household outlet charges the 1 kWh battery in roughly four hours. Faster chargers are available. Many customers charge overnight at the cottage.
Is the Avator covered under Mercury's warranty?
Yes. The Avator carries Mercury's Limited Warranty, and a promotional coverage extension is usually running. We confirm the exact current terms when we quote you.
