Overview / What Is Suzuki SG Dual – Suzuki (14.1 x 24″) Solas Rear Propeller?
This specific model — the Suzuki SG Dual 14.1 x 24 rear propeller — is the rear-facing propeller component in Suzuki’s dual contra-rotating propulsion system. Designed specifically for Suzuki DF325A and DF350A outboards, it works in tandem with a matching front propeller to increase grip and balance in the water, reduce cavitation, and provide more efficient power transfer to your boat.
Manufactured by Solas, this rear prop is crafted from corrosion-resistant stainless steel and built for optimal hydrodynamics. The 24” pitch is well-suited for larger boats or faster top-end performance — providing a perfect mix of thrust and speed for offshore trips and competitive marine use.

How to Install the Suzuki SG Dual Rear Propeller
Proper installation of the Suzuki SG Dual 14.1 x 24 rear propeller is essential to achieve optimal performance. It is recommended to install both front and rear props together, aligning the spline, washers, and torquing nuts to Suzuki’s factory specifications.
Steps to install:
- Remove the cotter pin and lock nut from the old propeller assembly.
- Clean and grease the propeller shaft.
- Install the front propeller first and secure it with a thrust washer.
- Install the rear propeller, aligning carefully with the spline.
- Use the special Suzuki dual-prop nut kit to secure both props.
- Torque the nuts according to Suzuki’s spec and install the cotter pin.
Note: Improper torque or misaligned splines can lead to vibration or gearcase damage.
Best Use Cases for the Solas 4653-141-240 Rear Propeller
The Solas 4653-141-240 propeller is specifically suited for boaters who:
- Own Suzuki DF350A or DF325A outboards with a dual propeller system
- Operate heavier vessels that require better grip and load-handling
- Need maximum thrust and speed for offshore or sport fishing applications
It also benefits those upgrading from aluminum or worn props who want longer durability, better fuel economy, and tighter handling at high speed.
Understanding Pitch and Diameter for High-Performance Boats
The 14.1″ diameter and 24″ pitch combination strikes a high-performance balance. Pitch refers to how far the propeller moves forward in one rotation. A 24-inch pitch is generally for higher speeds — making it perfect for boats that already have strong torque and want to maximize top-end efficiency.
If your RPMs are too high or the boat feels sluggish, you may be over-pitched or under-pitched. The Suzuki SG Dual 14.1 x 24 rear propeller helps find that sweet spot for Suzuki dual-drive systems when more speed and efficient push are needed.
Maintenance Tips
Keeping your Suzuki SG Dual 14.1 x 24 rear propeller in excellent condition will extend its life and maintain peak efficiency. Here are some important tips:
- Post-trip Inspection: Check for fishing line, dents, or damage after every outing
- Greasing: Apply marine grease to the shaft to avoid seizing or corrosion
- Hardware Tightness: Verify torque and check for wear around washers and spacers
- Offseason Storage: Remove the prop, clean thoroughly, and store in a dry place
Frequent checks and timely servicing will protect your propeller and your outboard motor’s lower unit from avoidable damage.

Detailed FAQ Section
Is the 4653-141-240 rear propeller compatible with non-dual propeller outboards?
No. This propeller is specifically designed for Suzuki’s Dual Propeller outboards like the DF350A and DF325A. Attempting to use it on a standard single-propeller setup can cause compatibility issues and mechanical failure. These dual systems are engineered with unique gearcases and drive configurations not shared with conventional outboards.
How does the 14.1 x 24″ rear propeller improve my boat’s performance?
With its 24″ pitch and counter-rotation design, this rear prop increases acceleration, enhances fuel economy, and improves maneuverability. The rear prop works in sync with the front prop, balancing torque and reducing slippage. For heavier boats or offshore conditions, this can significantly improve overall drive efficiency and handling.
Can I install the Suzuki SG Dual rear prop myself?
Yes, with the right tools and mechanical knowledge, you can install it yourself. Be sure to use a torque wrench, marine-grade grease, and follow Suzuki’s torque specs and install sequence. However, for first-time installations, it’s advisable to have a certified marine technician perform or supervise the process to ensure proper spline alignment and torque.
What should I do if the propeller is vibrating or underperforming?
Start by inspecting both front and rear props for dings, bent blades, or foreign object damage. Ensure the props are torqued correctly and not misaligned. Vibration can also indicate worn bearings or a bent shaft, which should be inspected immediately. If the problem persists, switch to a different pitch or have your props balanced professionally.
How long does a Solas stainless steel propeller last?
Solas stainless steel propellers are built to last many seasons — often 5-10 years with proper care. Regular inspections, proper torqueing, and preventative maintenance will extend the lifespan. Saltwater exposure, striking objects, and neglect can shorten its durability, so maintenance is key.
Conclusion
The Suzuki SG Dual – Suzuki (14.1 x 24″) Solas Rear Propeller, 4653-141-240 is an elite-level upgrade for boaters seeking top-end thrust, improved balance, and fuel economy in high-performance marine environments.
