9.9 HP Outboard Motors: 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.
