How to Install the Amita 3 1511-148-17 Propeller
Installing the Amita 3 Solas RH propeller is a straightforward process for most DIY-savvy boaters. Here are the basic steps:
- Turn off your engine and disconnect the battery.
- Use a prop wrench to remove the old propeller’s cotter pin and nut.
- Slide the old propeller off the shaft, noting the order of washers/spacers.
- Grease the shaft lightly with marine-grade lubricant.
- Slide the new Amita 3 propeller onto the shaft, reusing any washers or spacers.
- Secure with the prop nut and a new cotter pin.
Note: Always check your manufacturer’s manual or consult with a certified marine mechanic if unsure. An incorrectly installed prop can lead to reduced performance or damage to the lower unit.

To extend the life of your Amita 3 Tohatsu marine propeller, proper maintenance is essential:
- Inspect after every use: Look for dings, bends, or corrosion buildup
- Rinse with freshwater: Especially after saltwater outings
- Remove periodically: Grease the shaft and check for fishing line wraps
- Store correctly: When trailering, ensure the prop is secure
Regular maintenance will not only boost performance but also help you detect issues before they turn costly. Even the best aluminum props require preventive care to remain in optimal condition.

Detailed FAQ Section
What engines are compatible with the Amita 3 – Tohatsu/Nissan (14.8 x 17″) Solas RH Propeller?
This specific Amita 3 model (1511-148-17) fits a wide range of Tohatsu and Nissan outboard motors ranging from 90 to 140 HP. The propeller hub and shaft dimensions are engineered to fit OEM standards, making installation straightforward. Compatibility also extends to some Mercury outboards depending on the spline configuration. Always check your motor’s user manual or contact a marine propeller expert to confirm proper fitment before purchase.
How do I know if I need a 17-pitch propeller?
Pitch refers to how far the propeller moves your boat in one full rotation. A 17″ pitch propeller offers a good balance between acceleration and top-end speed for mid-size boats. If your engine over-revs or underperforms, a 17-pitch might be the right adjustment. Boat weight, engine power, and usage type all play a role in determining pitch suitability. The Amita 3’s 17” pitch is commonly ideal for boats looking to cruise comfortably without sacrificing fuel efficiency.
How long does an aluminum propeller like the Amita 3 last?
With proper care, aluminum propellers such as the Amita 3 can last several boating seasons. Durability depends on operating conditions, frequency of use, and maintenance. Aluminum props are more susceptible to damage from underwater debris compared to stainless steel but are also cheaper to replace or repair. Regular inspection and cleaning, especially after each trip, greatly improve their lifespan. Most boaters find Amita 3 props last 3–5 seasons under normal use.
Can I use this propeller in saltwater?
Yes, the Amita 3 is suitable for both saltwater and freshwater environments. It’s made of corrosion-resistant aluminum alloy with an anti-rust coating. To ensure long-term performance in saltwater, rinse the propeller with fresh water after each use and periodically remove it for shaft lubrication. Many saltwater boaters rely on the Amita 3 for its affordability and proven resistance to marine corrosion.
What should I do if the propeller is damaged?
If your Amita 3 propeller suffers from chips, bent blades, or severe wear, it should be replaced or repaired immediately. Small dings can sometimes be fixed by marine repair shops, but structural damage often requires a new prop to avoid lower unit damage. Continuing to use a damaged propeller can result in loss of performance, fuel inefficiency, and risk to your engine. We recommend keeping a backup propeller like the Amita 3 in your onboard toolkit.
Conclusion
Whether you’re upgrading your outboard prop or replacing a damaged unit, the Amita 3 – Tohatsu/Nissan (14.8 x 17″) Solas RH Propeller offers a balance of performance, affordability, and durability that’s hard to beat.
