Overview / What Is the New Saturn – Tohatsu/Nissan Propeller?
This specific propeller—Solas 3431-138-13—falls under the reputable New Saturn stainless steel series. It features a 13.75-inch diameter and a 13-inch pitch, making it ideal for Tohatsu and Nissan outboard engines within the 40–140 HP range. The right-hand rotation and 3-blade configuration are optimized for general-purpose boating and higher strength requirements.

Top Features and Performance Benefits
The Solas New Saturn series is known for its performance gains and engineering precision. Here are some of the standout features of the 3431-138-13 model:
- Material: Premium high-chromium stainless steel resists rust and wear.
- Pitch & Diameter: 13″ pitch and 13.75″ diameter for optimized thrust.
- Blades: 3-blade design enhances acceleration and top-end speed.
- Fuel Efficiency: Balanced geometry helps reduce fuel consumption at cruising speeds.
- Compatibility: Engineered to fit Tohatsu and Nissan outboards up to 140 HP.
Users switching from aluminum propellers often report immediate improvements in hole-shot acceleration and less vibration at mid-range RPMs. This propeller’s rigid structure also allows for better transmission of engine torque, especially useful in coastal, lake, and shallow water boating.
How to Install the Solas 3431-138-13 Propeller
Installing the New Saturn – Tohatsu/Nissan propeller is a straightforward task, especially for seasoned boat owners. However, proper technique is critical for safety and optimal performance. Here’s a basic overview:
- Ensure the engine is turned off and the key is removed.
- Remove the existing propeller by taking off the prop nut and washers.
- Inspect the propeller shaft and clean off any debris or corrosion.
- Grease the shaft lightly with marine grease.
- Slide the Solas propeller onto the shaft with the correct hub kit (sold separately if required).
- Secure with the included hardware and torque according to engine specifications.
Note: Always refer to your outboard’s manual for torque values and compatibility before installation.
Maintenance Tips
Even with corrosion-resistant stainless steel, regular care is essential to extend the lifespan of your Solas 3431-138-13 propeller. Here are the top maintenance tips:
- Flush After Saltwater Use: Saltwater can corrode even stainless steel over time. Rinse the propeller and lower unit with fresh water after every outing.
- Inspect for Dings and Cracks: Examine blades regularly for physical damage, which can affect engine performance and fuel economy.
- Reapply Marine Grease: Remove the propeller seasonally and re-grease the shaft to prevent seizing and corrosion.
- Check Hub Bushing: Monitor the rubber hub for signs of wear or slippage under load.
Following these steps will ensure reliable operation and preserve the performance of your propeller season after season.
Why Choose Stainless Steel for Tohatsu/Nissan Outboards?
While aluminum propellers are cost-effective and lightweight, stainless steel propellers offer a host of advantages for more demanding marine applications:
- Durability: Withstands impact damage and resists corrosion better than aluminum.
- Efficiency: Maintains blade shape under high torque, delivering consistent propulsion.
- Lifespan: Typically lasts 3–5x longer than aluminum propellers.
- Performance: Reduces cavitation and maintains top speed even in rough waters.
For boaters operating in saltwater or under heavy loads, upgrading to stainless steel—like the Solas 3431-138-13—is a wise long-term investment.
