As a rule of thumb, Honda outboard motors feature 1-6 cylinders depending on the model. To be more precise, the number of cylinders in each class is as follows:
- 2.3-5 HP: 1 cylinder
- 8-20 HP: 2 cylinders
- 25-60 HP: 3 cylinders
- 65-150 HP: 4 cylinders (inline-4)
- 200-250 HP: 6 cylinders (V6)

How Many Cylinders Does a Honda Outboard Have?
Single-Cylinder Honda Outboards
You can find small, single-cylinder engines in Honda BF2.3 and BF5 outboards, with displacements of 57 and 127cc.
These portable outboard motors only weigh 29-61 pounds, which makes them easy to handle and transport.
2-Cylinder Honda Outboards
The more powerful, 8-20 HP Honda portable outboards feature 2-cylinder engines.
There are two different engines in this breed, the 222cc twin delivers 8-10 HP, while the 350cc twin is rated at 15/20 HP.
3-Cylinder Honda Outboards
The 3-cylinder Honda outboard family includes many popular models like the BF25, BF30, BF40, BF50, BF60, and the unique Jet40.
These models come with three different engine configurations.
The BF25/30 have a 552cc triple rated at 25-30 HP, and the BF40/50 come with a 808cc triple rated at 40-50 HP.
The most powerful triple Honda outboard is the BF60, powered by a 998cc, 3-cylinder, 60 HP engine.
You can find the same power source in the Honda Jet40 outboard, but this model only delivers 40 HP.
4-Cylinder Honda Outboards
The 4-cylinder Honda outboard line includes many great models with engine power from 65-150 HP.
Each of these machines is powered by 4-stoke, SOHC, 16-valve, inline-4 engines displacing between 1496 and 2354cc.
To be more precise, the list of inline-4 Honda outboards is as follows:
- Honda JET65 (1496cc, inline-4, 65 HP)
- Honda BF75 (1496cc, inline-4, 75 HP)
- Honda BF90 (1496cc, inline-4, 90 HP)
- Honda BF100 (1496cc, inline-4, 100 HP)
- Honda JET105 (2354cc, inline-4, 105 HP)
- Honda BF115 (2354cc, inline-4, 115 HP)
- Honda BF140 (2354cc, inline-4, 140 HP)
- Honda BF150 (2354cc, inline-4, 150 HP)
