How to Install the Suzuki SG Dual Propeller
Installing the Suzuki SG Dual – Solas Front Propeller (4652-155-210) is straightforward but requires attention to proper alignment and torque settings:
- Ensure the engine is off and the battery is disconnected before beginning installation.
- Remove the existing front propeller (if any), checking for any wear or damage on the shaft.
- Apply marine-grade grease to the splines and slide the new Solas front propeller onto the shaft.

- Tighten the nut to the recommended torque specification as per Suzuki’s guidelines.
Note: Always install the front propeller before the rear propeller in the SG dual system.
Performance Benefits of a Dual Propeller System
The SG Dual system offers significant benefits over traditional single-prop setups:
- Improved thrust: Two counter-rotating propellers provide more bite in the water, boosting acceleration.
- Enhanced maneuverability: Excellent low-speed handling and docking precision.
- Reduced cavitation: Minimizes air pockets and improves water contact under load.
- Better fuel economy: More efficient propulsion reduces engine workload.
The 15.5 x 21″ Solas front propeller plays a key role in these advantages, making it ideal for heavy boats and rough conditions.
Maintenance Tips
To keep your Suzuki SG Dual – Solas Front Propeller performing at its best, follow these key maintenance guidelines:
- Rinse after every trip: Especially in saltwater, wash the propeller with freshwater to remove corrosive residues.
- Inspect for damage: Check blades for nicks, dings, or bends that can affect balance and performance.
- Lubricate splines: Use waterproof marine grease to prevent rust and ensure smooth installation/removal.
- Tighten periodically: Vibrations can loosen the prop nut over time – verify torque settings each season.
Regular inspections ensure your investment lasts longer and performs reliably in all marine environments.
