Selecting the right Suzuki outboard for your boat is the difference between a motor that feels right every trip and one you fight with. We sell the Suzuki range from 2.5 to 30 hp; here are the factors to weigh when choosing one.
- Boat size and type: Larger boats require more power, while smaller boats need lighter, more compact motors. Consider your boat's hull shape, weight, and intended use. A common rule of thumb is 1 hp per 25 to 40 lb of loaded boat weight; our guide to what size outboard you need works through it.
- Horsepower requirements: Consult your boat manufacturer's recommendations and match the motor's horsepower to your boat's design and performance needs. Remember, underpowered boats can strain the engine while overpowered boats may cause instability.
- Fuel efficiency: Suzuki's four-stroke engines are known for their efficiency and lower emissions. Weigh the benefits of fuel savings against your budget and usage patterns.
- Reliability and maintenance: Choose a motor with a proven track record and easy access to parts and service. Regular maintenance is essential to prolong the life of your outboard.
- Budget: Determine a budget that balances performance, features, and affordability. Don't forget to factor in the cost of maintenance, fuel, and insurance.
- Shaft length: Select the appropriate shaft length (short, long, or extra long) based on your boat's transom height; measuring the transom takes a minute and avoids an expensive mistake.
- Control options: Consider whether you prefer a tiller handle for direct control or remote steering from a console. Our tiller and remote mounting guide covers what each setup needs, and a conversion kit can move a DF9.9B, DF15A or DF20A from tiller to remote later.
- Electric vs. Manual start: Decide whether the convenience of electric start is worth the additional cost, or if a manual pull-start is sufficient. Electric-start motors ship without a battery; the Suzuki battery requirements chart lists the minimum for each model.
- Power tilt and trim: Assess whether you need it for shallow water or for adjusting the motor angle underway. On the DF9.9B, DF15A and DF20A the option is power tilt only; full power trim and tilt starts at the DF25A and DF30A.
- Color and aesthetics: While performance should be the primary consideration, you may want to choose a motor that complements the look of your boat, such as Suzuki's white finish option.
Weigh these factors and the choice usually narrows to one or two models.
Reading a Suzuki Model Code
Suzuki motors can be identified by their model numbers and the letters that follow, which describe the motor's features:
- "DF" indicates the motor is part of Suzuki's four-stroke series.
- The number after "DF" is the horsepower rating.
- The letters after the number describe the configuration:
- S - short shaft (15 in), for a 15-inch transom.
- L - long shaft (20 in), for a 20-inch transom.
- X - extra-long shaft (25 in), for a 25-inch transom. See our guide on finding the correct shaft length.
- H - tiller handle for steering and throttle control (no H means remote control).
- T - power tilt on the DF9.9B, DF15A and DF20A, and full power trim and tilt from the DF25A/DF30A up. T models are electric start, and T can be combined with H (a DF9.9BTH is a tiller motor with electric start and power tilt).
- E - electric start on a model without power tilt.
- W - white finish instead of the standard black.
- A and B - the model generation; A is the first major revision of a model and B the one after it (the DF9.9B replaced the DF9.9A).
For example, a Suzuki DF9.9BTXW5 is a 9.9 hp, extra-long shaft (25 in) motor from the B generation, with remote steering, electric start, power tilt (no trim on this size) and a white finish; the final 5 is the 2025 model year.
Once you have narrowed it down, the Suzuki outboard specifications chart lists weight, displacement and shaft options for every model, and our DF9.9B vs DF15A vs DF20A guide compares the three most popular portables head to head. If you are still unsure, contact us with your boat's make, length and transom height and we will point you at the right motor.
