3HP Outboard Motors | Info Dock (2024)

If you’re looking for a reliable, affordable, and easy-to-use propulsion solution, a 3 hp outboard motor may be the right engine for you. Electric motors, notably those in the 3 hp category, are known for their ease of use and maintenance-free operation. Boasting an output of 3hp, this particular electric outboard motor, equipped with a 2-inch (51 mm) impeller diameter, ensures swift and efficient movement, aided by its auxiliary power.

Also, while still able to go at speeds of up to 20 mph, an average 3 HP outboard motor weighs around 45 pounds or 20kg and requires no more than 100 hours of maintenance annually. It’s also one of the most convenient engines in its class. If your boat has a shallow draft or thin hull, this engine will be just what you need to get the job done.

How Fast Can It Go?

It all depends on the size and weight of the boat, but based on a 12-foot boat with a load of 330 pounds (150 kg), the maximum speed such a motor can provide is 5.5 miles per hour (9km/h).

Also, these electric motors, with their augmented electric motor capacity, can serve as robust auxiliary power units on heavier vessels like yachts weighing approximately 3,300 pounds.

Things to Consider Before Buying

Speed

Electric motors may not boast the top speeds of their gas-powered counterparts, yet they are praised for their efficiency and performance. They are optimal for small tenders and serve as effective auxiliary power on larger ships. For those desiring higher speeds, there are alternative power units available.

Weight

3HP motors are pretty light and weigh about 20 kg on average, which makes them reasonably practical. At the same time, do not forget about the weight specifications of the transom plate. Always consider the weight specifications of the transom plate to ensure both safety and optimal performance.

Price

Petrol and Electric 3HP motors are relatively cheap, ranging from $1,000 to over $2,000, depending on the model and specification. At the same time, there is a significant difference between gas and electricity motors prices.

While electric outboard motors can command a higher initial investment, the long-term benefits, including lower operational and maintenance costs can make them a cost-effective option over time.

Gasoline engines have their place, offering affordability and a broader market presence. However, electric motors are making significant strides, with advancements in technology making them increasingly cost-effective. Their longer range, attributed to efficient auxiliary power, is a noteworthy feature.

Electric outboard motors now come with two shaft lengths, offering options for both short shaft and alternative shaft lengths. The inclusion of a tiller handle ensures enhanced control and a superior boating experience. Additionally, the reverse gear feature ensures easy navigation in diverse water conditions.

FAQs

How much does a 3 hp outboard motor weigh? ›

Around 42 lbs

How fast will a 3hp outboard go? ›

To give you a simple reference, a 3 hp electric outboard can push a 12 ft boat with 150 kg (331 lbs) load at a max speed of 9 km/h (5.6 mph). That's to say the 3 hp outboard motor can provide more than sufficient propulsion for a 10 ft tender or work as an auxiliary power for a daysailer of up to 1.5 tonnes (3307 lbs).

Can you lay a small outboard motor on its side? ›

2-stroke outboards can be transported on both sides, but it's better to transport them lying on the tiller side. 4-stroke outboards should only be transported lying on the tiller side. For longer breaks in use and for wintering, outboards should be stored upright, for example using a transport stand for outboards.

How much thrust does a 3hp outboard have? ›

That would put a 3 hp around 60 lbs thrust which IMO is being generous--I would put them about equal to a modern 50 lb troller. I don't know of anywhere to get parts for them nowdays.

Are air cooled outboards good? ›

Conclusion. Generally speaking, the air cooled outboard motor is easier to maintain but with more noise and overheating problems. In fact, these days, the vast majority of outboards are cooled by the water the boat is used in, and air cooled outboards are favored in some specialized applications.

Are 2-stroke outboards heavier than 4-stroke? ›

Because they have fewer parts, 2-stroke motors are generally smaller and lighter than 4-stroke motors. Lighter weight also allows 2-stroke engines to run faster. As a result, when making a 2-stroke vs. 4-stroke outboard power comparison, 2-stroke motors usually win out.

How powerful is 3hp motor? ›

In fact, 3hp single-phase motors are rated at 2,200w - a little less than an electric kettle, and if it wasn't for start-up surges, inrush currents, whatever, then 10a is basically what they draw.

Is 200 hours a lot for an outboard motor? ›

Boat Engines:

Typically an average gas engine will run about 1500 hours before it needs a major overhaul. That means when properly maintained on a routine basis with around 200 hours a year, it will last for more than seven years.

Is 500 hours a lot for an outboard motor? ›

What are the Ideal Hours for an Outboard Motor? Most experts say you can expect to get 1,500 hours out of a gas boat engine before it needs to be rebuilt.

Do small outboards need a transom saver? ›

In general, I found that smaller boats and trailering situations where there is limited clearance between the outdrive and the ground benefit the most from the use of a transom saver. The best advice is to follow the recommendations from your boat and motor manufacturer.

Should outboard motor be up or down when docked? ›

It's best to tilt your outboard up when leaving your boat in the water to prevent marine growth from forming and from corrosion eating away at its metal parts.

How far down should outboard motor be in water? ›

Proper Height for Outboard Motor

If you are running an outboard motor without a cavitation plate (as most electric outboards are designed to be), the outboard motor height is decided differently where the top of the propeller should be kept 100 mm to 150 mm below the water.

How heavy is a 3hp motor? ›

38.6 pounds

How much power does a 3hp motor consume? ›

3 HP = 2.238KW, considering 0.746KW is one HP. If run for 24Hrs, it will consume 2.238x24=53.712KWH or units.

How many HP is 55 lbs of thrust? ›

Using this formula the popular Newport Vessels NV-Series 55lb Thrust Trolling Motor is rated as 624 watts at the highest forward speed and so 624/746 = 0.84 and would be roughly equivalent to a 0.84 horsepower motor.

How heavy is a 3.5 hp outboard? ›

The 3.5 HP Mercury boat motors model # 3.5MLH comes equipped with the 20 inch long shaft, tiller steering and manual start.
