Choosing an electric outboard isn't just about matching an electric motor to the horsepower of the gas outboard you're replacing.
Boat weight, hull design, passenger load, wind, current, trip distance, and even how often you need to carry the motor can all affect which electric outboard is right for your boat.
For smaller boats, tenders, dinghies, and daysailers, the current Torqeedo Travel lineup offers three power levels: 700 W, 1,100 W, and 1,600 W, with performance comparable to approximately 2 HP, 3 HP, and 5 HP combustion outboards.
Here's what to consider before choosing your motor.
Start With Your Boat Size and Weight
Boat weight is one of the most important factors when sizing an electric outboard.
A small, lightweight inflatable requires considerably less power to move than a heavily loaded tender or displacement sailboat.
Torqeedo's current Travel lineup provides a useful starting point:
| Motor | Input Power | Gas-Equivalent Class | Typical Application |
|---|---|---|---|
| Travel XS | 700 W | 2 HP | Small, lightweight boats |
| Travel | 1,100 W | 3 HP | Tenders, dinghies & daysailers up to approx. 1.5 tonnes |
| Travel XP | 1,600 W | 5 HP | Larger tenders, dinghies & daysailers up to approx. 2 tonnes |
These recommendations are a starting point. Your boat's actual operating weight and conditions matter too.
Don't Forget Passengers and Gear
Your boat doesn't operate at its empty weight.
Passengers, fishing gear, safety equipment, supplies, and other equipment can add a significant amount of weight.
A small tender carrying one person on a short trip to shore has very different power requirements than the same tender carrying three adults, groceries, and equipment back to an anchored boat.
When choosing an electric outboard, think about your normal loaded boat, not just the specifications printed by the boat manufacturer.
If you're frequently operating near the upper end of a motor's recommended application, stepping up in power may provide better performance when the boat is loaded.
Consider Your Hull Design
Two boats of similar weight won't necessarily require the same amount of power.
Inflatables, hard-bottom tenders, displacement hulls, and sailboats all move through the water differently.
Small displacement boats also have practical speed limitations. Adding substantially more power doesn't necessarily mean you'll travel proportionally faster.
That's why choosing the largest motor isn't always necessary.
Additional power may be more valuable for maintaining performance under load or in changing conditions than for increasing top speed.
Where Will You Be Boating?
The same boat can have very different power requirements depending on where it's used.
A small tender travelling across a protected lake or marina may perform well with a lower-powered electric outboard.
Coastal boating introduces additional considerations.
Wind, chop, and current can all increase the amount of power required to maintain headway.
For boaters around Vancouver Island and the BC coast, this is particularly important. A calm morning can turn into a windy afternoon, and tidal currents can significantly affect a small boat's performance.
If you regularly operate in these conditions, having additional power available may be worthwhile.
How Much Electric Outboard Power Do You Need?
For a small, lightweight boat used primarily in protected water, a motor in the 700 W / 2 HP-equivalent class may be sufficient.
For a typical recreational tender, dinghy, or small daysailer, moving up to approximately 1,100 W / 3 HP equivalent provides additional versatility for passengers, equipment, and changing conditions.
For a larger or heavier boat, heavier loads, or more demanding coastal use, a 1,600 W / 5 HP-equivalent motor provides considerably more available power.
The current Torqeedo Travel family follows exactly this progression with the Travel XS, Travel, and Travel XP.
Power and Range Are Different
It's important not to confuse motor power with battery range.
A more powerful motor gives you more available propulsion power.
A larger battery gives you more stored energy.
If your motor isn't powerful enough for your boat and conditions, simply adding a larger battery won't solve the problem. Likewise, choosing the most powerful motor doesn't automatically give you the longest range.
Your motor and battery should be considered together.

Portability Matters Too
One major advantage of portable electric outboards is the ability to separate the motor and battery for transport.
If you remove your outboard every time you return to the dock, weight matters.
A smaller motor and battery combination may make more sense for someone carrying their outboard down a dock every weekend than for someone who leaves the motor installed on the boat.
Think about where the motor will be stored, how often you'll carry it, and who will normally be moving it.
Don't Size Your Motor Only for Perfect Conditions
It's easy to choose an outboard based on a calm day with an empty boat.
That's not necessarily the day when you'll need the motor most.
Consider what happens when you add another passenger, load the boat with equipment, encounter a headwind, or have to travel against current.
You don't necessarily need to dramatically oversize your motor, but having reasonable capacity in reserve can make your boat considerably more useful when conditions change.
Choosing the Right Electric Outboard
Before buying an electric outboard, ask yourself:
- How much does my boat weigh when loaded?
- How many passengers do I normally carry?
- Am I boating on protected water or the coast?
- Will I regularly encounter wind or current?
- How far do I normally travel?
- How important is portability?
- How much power do I realistically need?
Once you understand those requirements, choosing the right motor becomes much easier.

Frequently Asked Questions
How much electric outboard power do I need for a dinghy?
It depends on the dinghy's size, weight, passenger load, and operating conditions. A small, lightly loaded dinghy used in protected water may require considerably less power than a larger inflatable carrying several passengers in coastal conditions.
Is a 3 HP-equivalent electric outboard enough for a tender?
For many tenders, a 3 HP-equivalent electric outboard can be an excellent fit. Always consider the boat's loaded weight and where it will be used.
Do I need a bigger electric outboard for saltwater?
Saltwater itself doesn't automatically mean you need more power. However, coastal boating often involves current, wind, waves, and heavier loads, which may make additional power useful.
Does a more powerful electric outboard give me more range?
Not necessarily. Motor power and battery capacity are different. Range depends on available battery energy, throttle setting, boat efficiency, load, and operating conditions.
