Is there an electric outboard in your future? The launch of the Mercury Avator 7.5e
By Jerry MonaPublished On: February 5, 20231012 words
There has been tremendous focus within the boating industry in recent years on developing electric, more environmentally friendly, boats. Initial efforts, while intriguing, have often fallen short in terms of practicality and affordability. Take for example the all-electric, Nautique GS22E wake boat that was introduced in 2020. While it would be cool to surf around in a quiet and peaceful environment for the 2-3 hours of run time, I doubt few could afford the $300K price tag.
And they are not alone. In 2021, General Motors invested $150 Million dollars into the little-known electric outboard company called Pure Watercraft. Since that time, they have partnered with various boat manufacturers to produce a mix of electric watercraft – including this pontoon boat that starts at $75K – a bargain compared to the Nautique.
But electric outboards are nothing new. In fact, one of the early pioneers – Elco – has been producing them since 1893. And Torqeedo, likely the most popular brand currently, has been in the clean and quiet propulsion game for nearly 20 years.
About the Mercury Avator 7.5e
Despite these earlier efforts, the entry by Mercury – the world leader in marine propulsion – could be a signaling a major shift in the direction of marine propulsion.
The Avator 7.5e, introduced at the 2023 Consumer Electronics Show in Las Vegas, is the first of a series of electric motors to be released by Mercury this year. According to the company press release, the 7.5e delivers “750W of power at the propshaft and produces similar speed and acceleration as a Mercury 3.5 HP FourStroke.”
One neat feature of the engine is its lithium-ion “swappable” battery system. If your power is running low, you can easily pop in a new power pack just like you do with a cordless weed-wacker or drill. Another nice touch is the clear power display on the front of the motor to always let you know how much juice is remaining. This is important because “range-anxiety” is a common concern among electric car owners.
Mercury Avator Price (*updated*)
Of course, the key question everyone wants to know is the Mercury Avator price. At the time this article was first written, pricing information was unavailable. However, the company began shipping the Mercury Avator 7.5e on April 19, 2023 and I was able to find pricing information from an online dealer soon thereafter.
According to the NuWave Marine website, the Mercury Avator price is listed at $3,510 as of this writing. This is for a 15″ shaft length, tiller handle model with one battery. By comparison, the cost for a Mercury 3.5 HP four-stroke – which has similar speed and acceleration – is much less at $1,106. Of course, the actual price will likely vary from dealer to dealer. Nonetheless, you can expect that the cost will be around 3X that of a conventional outboard.
Anticipated Advantages and Disadvantages
Though I have not yet had the opportunity to operate the Mercury Avator 7.5e, the pluses and minuses vs. a traditional (3.5HP) four-stroke motor are likely to be as follows:
Reliability: Electric motors have far fewer moving parts than a traditional internal combustion (gas) engine. Therefore, in theory, they should be more reliable.
Performance: According to the company website, the Avator 7.5e delivers 52% quicker acceleration than an unnamed “competitor”. This is not surprising given that electric engines, unlike gas, do not need to build up RPMs to produce torque. Top speed is not mentioned but I would expect it to be comparable, or slightly less, than that of a four-stroke.
Operating Characteristics: This, of course, is where electric engines really shine. The company reports that Avator transmits 80% less vibration and is 75% quieter at full throttle. But, given the quality of today’s four-stroke engines, this difference might not be a huge factor to most boaters.
Range: How far you can travel with the Avator depends on how aggressively you use it. Mercury put together this informative chart that shows the maximum runtime at various speeds. At full throttle, the run time is only 1 hour which, at first, seems pretty limited. However, the internal tank of the Mercury 3.5 HP four-stroke only holds about 0.3 gallons which also would only last about one hour at 100% throttle. So, unless you connect an external gas tank, the difference might not be too dramatic.
Maintenance: There is almost zero maintenance required on electric motors – an advantage vs. combustion engines. However, the amount of maintenance required on smaller, gas-powered, outboards is pretty minimal to begin with and so the actual benefit is fairly minor.
Portability: One of the things Mercury touts on its website is the “portability” of the motor. However, at 43 lbs, it is slightly heavier than the four-stroke and the difference is even greater if you factor in the weight of the battery (17 lbs). But, at least you don’t run the risk of gas spilling out.
Cost of Ownership: Given that the Mercury Avator outboard price is about 3X that of a conventional engine, it is highly unlikely that any fuel and maintenance savings will ever offset the initial investment. If you want to buy one of these, it will have to be for reasons other than the cost.
Who is the Avator Best Suited For?
Considering the advantages and disadvantages above, I think Mercury is spot-on regarding who the product is best suited for – ” it’s ideal for powering many small boats, including tenders, jon boats, inflatables and kayaks”. Sailboats are another possible application too because they typically only need power for relatively short periods of time and because the sailing community is conditioned to appreciate its clean, quiet operating characteristics.
So, will Mercury sell a lot of these? That is doubtful barring any government regulations such as what occurred in the early 2000s that gave rise to clean two-strokes and eventually four-stroke motors. Regardless, the Avator – along with Nautique GS22E and others before them – will likely be a catalyst for further innovation. Not coincidently, Brunswick (the parent company of Mercury) just introduced its new tagline of “Next Never Rests™”.

Rich G., 1998 Tiara Yachts 3500 Open
“The Formula brand is a well-built boat that uses high end components and has things such as fume detection for the bilge and other items like that are not seen on other brands. The seats are very comfortable and both interior and exterior are holding up extremely well. The boat handles great and has a very solid ride.” (Overall Rating: 10)
Capt Stubbing, 2005 Formula 37 PC
“Not many people are very familiar with Bryant but they build a quality boat that is a bit more affordable than some of the other premium names. I have had this boat 5 years now and it looks great and rides well.” (Overall Rating: 9)
Jerry M., 2013 Bryant 210
“It’s the best all-weather boat I’ve owned for lakes. Handles just about anything that’s marginal to get back to the ramp safely. And plenty of storage room, actually it could be too much room at times.” (Overall Rating: 10)
Howard B., 2015 Nitro Z7
“When I bought it , it was probably the best deal one could find for a fiberglass bass boat with absolutely no wood in it. The boat and Yamaha 70 have performed flawlessly for 12 years.” (Overall Rating: 10)
Jerome K., 2008 Stratos 176XT
“This model falls into the category that most salt water fishermen refer to as “Bay Boat”. It has a center console which provides tremendous stability and a deeper hull than a “flats” boat for smoother ride on choppy water. The boat is made for fishing and has very few comfort features for cruising. It is not my favorite hull because it draws a little more water than some of the other shallow water bay boats such as Pathfinder.” (Overall Rating: 9)
Ken L., 2005 Key West 196 Bay/Reef
“Great boat, solid ride… great bay boat for fishing. Fast with Yamaha 300!!” (Overall Rating: 10)
Rich N., 2023 Robalo Cayman 246 SD
“Excellent high-end Pontoon Boat with a 400hp R Mercury outboard Racing motor. Too nice to be a Pontoon Boat. Rear twin electric recliners.” (Overall Rating: 9)
Don M., 2019 Avalon Excaliber
“We had a lot of fun using this boat the past summer. it can accommodate nine persons, has comfortable seating for all passengers, is easy to board for both passengers and water skiers, handles well in rough water, is easy to launch and dock, looks great on the water and drew lots of compliments from all who saw it on the water.” (Overall Rating: 10)
John S., 2022 Tahoe T18
“Great boat and a great price point. Carolina flare and deadrise makes for an exceptionally dry boat which I would expect from any Carolina boat builder that builds primarily for the Atlantic. This is not a shallow draft boat for its size, however….I would say it drafts in 12″ +.” (Overall Rating: 8)
Rich N., 2020 Kencraft 218 Bay Rider
