Why 9.9 HP Outboards
If you have been browsing around, you will find 9.9 HP outboards from a lot of reputable manufacturers. Some big names include Yamaha, Mercury, Evinrude, Tohatsu, Suzuki, Johnson, Gamefisher, and ePropulsion.
So why do they make 9.9 HP outboards instead of 10 HP?
Simply put, some lakes allow boat motors under 10 HP only. That’s to say, with 9.9 HP outboard motors, you can make the best use of the outboard if you plan to fish in a local lake with a 10 HP restriction.
Besides that, 9.9 HP outboards don’t need registration in some states as required by 10 HP boat motors.
That’s why so many outboards are rated 9.9 HP, but that’s not the only reason that makes this model popular.
The small 9.9 HP outboard is also popular for those who fish in skinnier water and smaller rivers.
A lot of users favor the 9.9 HP outboard motor for its impressive performance given its weight and price over other higher-powered models.

9.9 HP Outboards: Is It Enough?
Thinking about getting a 9.9 HP outboard and wondering whether it is enough for your boat?
It depends on what you’re looking for and what size boat you have. There are three easy ways for you to decide whether the 9.9 HP outboard motor is your best pick.
#1. Learn the Rule of Thumb
Generally speaking, the 9.9 HP outboards are suitable for aluminum fishing boats, dinghies, daysailers and cruising sailboats.
To be more specific, the 9.9 HP motor works best on boats ranging from 11′ – 16′ (up to 4.5m) to provide a satisfying speed. It’s also commonly seen on larger sailboats (over 30′) to provide decent auxiliary power.
#2. Check Test Reports
The most reliable way to know whether the 9.9 HP outboard motor is a good fit for your boat is to check the test report in real-world applications.
Here we have prepared various in-depth 9.9 HP outboard motor reports on different boats, so you can easily compare and know what works in your specific boating scenario.
- Use case #1. Navy 6.0 (9.9 HP) + Quintrex 420 Explorer (14′)
Power (W) | Speed (mhp / kph) | Runtime (hh: mm) | Range (mile / km) |
210 | 2.8 / 4.5 | 28:36 | 80 / 128.75 |
390 | 3.6 / 5.8 | 15:18 | 54.8 / 88.2 |
750 | 4.5 / 7.2 | 8:00 | 35.8 / 57.6 |
1500 | 5.4 / 8.7 | 4:00 | 21.6 / 34.8 |
3000 | 6.6 / 10.6 | 2:00 | 12.5 / 20.1 |
4500 | 7 / 11.3 | 1:18 | 9.1 / 14.7 |
6000 | 7.5 / 12.1 | 1:00 | 6.9 / 11.1 |
- Use case #2. Navy 6.0 (9.9 HP) + Olga 33 (33′)
Power (W) | Speed (mph / kph) | Runtime (hh: mm) | Range (mile / km) |
500 | 4 / 6.4 | 20:00 | 80 / 128 |
1000 | 4.9 / 7.9 | 10:00 | 49 / 79 |
2000 | 5.4 / 8.7 | 5:00 | 27 / 43.5 |
3000 | 6.2 / 10 | 3:20 | 20.7 / 33.3 |
4000 | 6.5 / 10.5 | 2:30 | 16.3 / 26.3 |
5000 | 7.1 / 11.4 | 2:00 | 14.2 / 22.8 |
6000 | 7.5 / 12 | 1:40 | 12.5 / 20 |
As you may have noticed, the runtime can be greatly extended if you adjust the power to lower settings, which can reduce the stress of battery drain and is a great plus for electric 9.9 HP outboard motors.
