This article dives deep into the technical features, maintenance guidance, expert insights, and commonly asked questions to provide you with everything you need to know about this standout marine product.
Overview / What Is the New Saturn – Tohatsu/Nissan Solas 3431-135-15 Propeller?
The Solas 3431-135-15 is a part of the New Saturn series—recognized for its corrosion-resistant stainless steel construction and high-performance capabilities. This propeller measures 13.5 inches in diameter with a 15-inch pitch, making it a suitable match for Tohatsu and Nissan outboard engines typically ranging from 40 to 140 HP.
Its 3-blade, right-hand rotation design ensures optimal thrust in both saltwater and freshwater conditions. The prop is engineered to reduce vibration, improve fuel economy, and provide consistent top-end speed, even under heavier loads. With its upgraded materials and efficient hydrodynamics, it’s a reliable replacement for stock aluminum props.
Why Diameter and Pitch Matter in Prop Selection
Choosing the right pitch and diameter is essential when selecting a propeller. The 13.5-inch diameter paired with a 15-inch pitch on this model is optimized for boats that require solid acceleration while maintaining fuel-efficient cruising RPMs. Here’s why it works so well:
- Diameter: Larger diameters increase surface area, creating more thrust—ideal for heavier boats or towing.
- Pitch: A 15-inch pitch provides a balance between low-end torque and top-end speed, perfect for mid-range outboards.
This setup ensures your engine doesn’t over-rev while still allowing your vessel to achieve smooth plane and responsive handling in various water conditions.
Best Use Cases for the Solas 3431-135-15
The Solas 3431-135-15 propeller is a versatile choice suited for:
- Recreational cruisers
- Inshore/offshore fishing boats
- Light-duty commercial vessels
- Watersports and towing setups
Thanks to its stainless steel construction, this propeller is ideal for operators who venture into saltwater areas or need durability in rough environments. It’s a favorite among weekend boaters who want a dependable, low-maintenance upgrade from standard aluminum props.
Maintenance Tips
To maximize the life and performance of your Solas 3431-135-15, routine maintenance is essential. Here are proven tips to keep it in top shape:
- Rinse after use: Always flush with fresh water after boating in saltwater to prevent corrosion buildup.
- Inspect the blades: Check for any nicks, chips, or bends that could throw off the balance and reduce engine efficiency.
- Remove seasonally: At the end of each boating season, remove the propeller, inspect for fishing line or debris wrapped around the shaft, and reapply marine grease.

Detailed FAQ Section
What engines are compatible with the Solas 3431-135-15 propeller?
The Solas 3431-135-15 is specifically designed for mid-range Tohatsu and Nissan outboard engines in the 40–140 HP range. It fits models that use a standard 13 spline shaft. Always check your engine’s specs and prop shaft compatibility before purchase. If you’re unsure, contacting a marine technician or using a prop selector tool from Solas’ official site can confirm the fitment.
How does stainless steel improve performance over aluminum propellers?
Stainless steel is significantly more rigid than aluminum, allowing for thinner blades and more precise designs. This results in increased fuel efficiency, smoother acceleration, and better top-end speed. Stainless steel also resists corrosion and deformation better, especially in saltwater. While aluminum is cheaper upfront, stainless steel often saves money in the long run due to fewer replacements and better performance metrics.
Can I install the Solas 3431-135-15 myself?
Yes, installation is straightforward for anyone comfortable working on marine engines. The job requires a propeller wrench, marine grease, and a torque wrench. It’s essential to follow installation steps closely and use the correct hub kit if needed. If you lack experience or tools, a local marine shop can install the prop in under an hour. Always check for fishing line or debris when removing an old propeller.
How often should I inspect or maintain my propeller?
It’s best to inspect your propeller after every 2–3 trips and more frequently if operating in debris-heavy or shallow waters. At minimum, perform a detailed check every 25 engine hours. Remove the prop at least once per season for thorough cleaning and lubrication. Propeller neglect is one of the most common causes of fuel inefficiency and engine strain.
