DF350A vs DF300AP vs DF300B – 2025 Suzuki Outboard Buyer’s Guide

March 06, 2025

Suzuki DF350A

Horsepower: 350 HP
Propeller System: Dual Prop
Fuel Requirement: 91 Octane Premium
Best For: Offshore fishing boats, larger center consoles, and performance-driven vessels needing maximum power and grip.

Suzuki DF300B

Horsepower: 300 HP
Propeller System: Dual Prop
Fuel Requirement: 87 Octane Regular
Best For: Heavier boats where added propeller grip improves control, or boats where dual prop efficiency is a priority.

Suzuki DF300AP

Horsepower: 300 HP
Propeller System: Single Prop
Fuel Requirement: 87 Octane Regular
Best For: Mid-sized boats needing reliable, affordable performance without requiring premium fuel.

Dual prop technology uses two counter-rotating propellers on the same engine instead of a single larger prop. This design offers several benefits:

• Superior Grip: Two props bite the water better than one, which helps maintain control in rough water or tight turns.
• Faster Acceleration: Dual props transfer power more efficiently, delivering stronger hole shots.
• Better Reverse Control: With two props spinning in opposite directions, the boat responds more predictably in reverse — a real plus when docking.

Both the Suzuki DF350A as well as their DF300B models have dual prop available!

Choosing the right Suzuki outboard depends largely on how you plan to use your boat. Are you a passionate offshore fisherman who needs the best power for cutting through waves and carrying heavy loads? The DF350A is your go-to engine. On the other hand, if you’re looking for a more versatile option that works well for family outings, watersports, or casual cruises, the DF300AP will provide a great mix of performance and efficiency. For those with larger or heavier boats that need a steady, powerful motor to keep everything running smoothly, the DF300B steps up to the plate. If you’re all about squeezing out the most horsepower for thrilling adventures, the DF350A delivers the power you crave. And if fuel efficiency is top of mind, while still needing some solid performance, the DF300AP is the clear winner. Finally, if dual propellers are important for stability and smoother handling, both the DF350A and DF300B come with this feature, making them excellent choices for those seeking precision in their boating experience.

• Offshore Fishing:   DF350A
• Family Boating, Versatility:   DF300AP
• Larger, Heavier Boats:   DF300B
• Seeking Maximum Power:   DF350A
• Focused on Fuel Savings:   DF300AP
• Want Dual Prop Benefits:   DF350A or DF300B

When it comes to fueling your Suzuki outboard, the choice of engine affects not just performance, but your long-term running costs. If you’re aiming to keep fuel costs manageable while still getting great performance, the DF300AP is an excellent choice, as it runs on 87 octane regular fuel, which is typically cheaper. For those who want maximum power and don’t mind a slight bump in fuel expenses, the DF350A requires premium 91 octane fuel to reach its peak performance levels. While this engine offers the most power, it’s something to keep in mind if you’re looking for a more budget-friendly option. If you’re after dual prop benefits for better stability but want to avoid paying for premium fuel, the DF300B is a smart pick — it runs on the same affordable 87 octane as the DF300AP, making it a more cost-effective choice without sacrificing the advantages of dual propellers.

• DF300AP: Runs on affordable 87 octane regular fuel — great for boaters watching long-term fuel costs.
• DF350A: Requires premium 91 octane fuel for peak performance, which adds to running costs but delivers maximum power.
• DF300B: Also runs on 87 octane, offering dual prop benefits without requiring premium fuel.

All three Suzuki models come with a 5-year limited warranty, provided they’re regularly serviced by a certified Suzuki technician. While each model requires routine maintenance, the DF350A and DF300B (dual prop models) demand more attention to their lower units due to the added complexity of two props. This means more frequent checks and servicing to keep everything running smoothly. Regardless of the model, sticking to Suzuki’s recommended service intervals ensures the engine stays in peak condition and that your warranty remains valid.
