Amita 4 – Evinrude/Johnson (9.25 x 11″) Solas RH Propeller, 4113-093-11A

Introduction

The Amita 4 ‑ Evinrude/Johnson (9.25 × 11″) Solas RH Propeller, 4113‑093‑11A is engineered to enhance marine propulsion for small to mid‑sized craft powered by Evinrude or Johnson outboards. Designed for optimal thrust and speed management, this right‑hand (RH) rotation propeller features a robust aluminum build, precise pitch control, and four‑blade performance. Ideal for fishing boats, pontoons, or inflatables needing better acceleration and fuel economy, the propeller adapts to varied sea conditions with ease. Whether upgrading from a stock 3‑blade unit or replacing a worn prop, the Amita 4 delivers reliability, efficiency, and long‑term durability that boaters demand in marine propulsion. Sellers and manufacturers report enhanced hole‑shot, improved stern lift, and reduced cavitation compared to older designs.

Overview / What Is the Amita 4 9.25×11 RH Propeller

The Amita 4 (4113‑093‑11A) is a squeeze‑cast aluminum propeller crafted using advanced CAD tooling to ensure blade symmetry, consistent pitch, and durable geometry. With a 9.25” diameter and 11” pitch, the design balances torque and speed—particularly suited for heavier boats or setups needing more thrust at cruising RPM.

Its four‑blade configuration improves acceleration from rest (hole‑shot), reduces ventilation during planing, and offers smoother handling in rough or choppy waters. The RH rotation makes it compatible with standard installations on Evinrude/Johnson outboards. A multi‑layered finish resists corrosion in saltwater environments and ensures longevity in fresh water as well.

Technical Specifications and Key Features

• Blade Design: Four blades for improved lift and stability.
• Material: Squeeze‑cast aluminum ensures strength and weight efficiency.
• Size: 9.25″ diameter × 11″ pitch.
• Rotation: Right‑hand (RH) rotation standard for Evinrude/Johnson.
• Finish: Protective powder coating resists corrosion.
• Compatibility: Fits 8‑15 HP, standard shaft outboards from Evinrude/Johnson.

These features make the Amita 4 ideal for boats that need improved acceleration, better stern lift, and more efficient cruising at mid‑range RPM.

How to Install Amita 4 4113‑093‑11A Propeller

Installing the Amita 4 Evinrude marine propeller is straightforward and can be completed with minimal tools:

1. Turn off the engine, shift to neutral, and disconnect battery.
2. Remove the current propeller by removing cotter pin, nut, and washer sequence.
3. Clean the prop shaft thoroughly—remove fishing line or debris and apply marine grease.
4. Slide the new propeller onto the shaft, align washers, and torque nut per engine manual.
5. Insert cotter pin securely and check freeplay—propeller blades should spin smoothly.

Warning: Always follow torque specs in your engine manual—under‑torquing or over‑torquing may lead to propeller slip or shaft damage. Use marine‑grade grease to prevent corrosion and ease removal later.

Amita 4 9.25×11 Maintenance Tips

Proper maintenance extends the lifespan and ensures consistent performance of your propeller:

• Rinse prop after each saltwater use with fresh water.
• Inspect blades and hub for nicks, bends or corrosion signs.
• Grease shaft regularly—every 20‑30 hours of runtime.
• Annually remove the prop to check for fishing line damage to seals or bearings.
• Address small dings immediately—file smooth or seek repair to prevent imbalance.

Following these Amita 4 Evinrude marine maintenance tips ensures top performance season after season.

Troubleshooting Common Issues with Amita 4 Propellers

Here are common problems users encounter and how to solve them:

If you notice vibration or loss of speed, check for blade damage or prop slip due to under‑torqued nut. Bent blades reduce efficiency and stress the engine. Replace or repair damaged blades promptly.

If experiencing cavitation (bubbles forming near blades) or ventilation (air being drawn from surface), it may signal wrong pitch relative to RPM or engine trimming issues. Adjust engine trim or consult with propeller experts to choose suitable pitch for your boat weight.

Best Amita 4 9.25×11 Propeller Options Comparison

When comparing the Amita 4 4113‑093‑11A against other prop options:

• 3‑blade stock props deliver higher top‑end speed but less low‑end thrust.
• Other Amita 4 sizes (e.g. 9.25×9, 9.25×10) offer different pitch performance—choose pitch based on engine RPM and boat load.
• Stainless steel props weigh more and cost significantly more while offering marginal gains for low‑powered outboards.

The 9.25×11 model provides ideal torque for boats with heavy loads or those needing stronger planing from idle. Many users call it one of the best Amita 4 propeller options for mixed freshwater/saltwater use.

Expert Advice and Pro Recommendations

Marine experts frequently suggest the Amita 4 – Evinrude/Johnson 4113‑093‑11A when upgrading from a standard propeller. It excels in situations where you tow, load cargo, or navigate choppy water. Its four‑blade geometry reduces ventilation and enhances control at low speeds.

Frequently Asked Questions

What scenarios call for a 9.25×11 propeller over 9.25×9 or 9.25×10?

Choosing the 9.25×11 pitch is ideal if you operate heavier boats or carry loads that slow acceleration. The greater pitch provides improved thrust at moderate RPMs, helping to reduce over‑revving and improving fuel economy. For lightweight vessels or solo anglers, a lower pitch propeller may allow higher top speeds. However when towing, carrying gear, or running rough water, the extra pitch torque of the 9.25×11 makes it one of the best Amita 4 propeller options for consistent, efficient propulsion.

This pitch also reduces cavitation and improves planing at idle RPMs, making it a solid choice across both freshwater and saltwater environments. Boat owners experiencing ventilation issues or under‑powered starts often report better performance after switching to the 9.25×11 model.

How to install the Amita 4 4113‑093‑11A propeller safely?

Installation is straightforward following your outboard’s manual. Begin by disconnecting the battery and ensuring the engine is in neutral. Remove lodging contaminants—particularly fishing line wrapped around the shaft. Use marine grease liberally on the shaft to prevent seizure. Slide the propeller onto the shaft, fit the washers and nut, and torque to the specified value. Secure the cotter pin correctly so the prop swaps don’t loosen. Finally, confirm the propeller spins freely and check for freeplay. Always consult engine documentation for torque specs and installation procedures.

Having tools like a torque wrench, grease, replacement cotter pins, and protective gloves streamlines the process. With proper installation, the prop performs reliably without damage to engine components or shaft bearings.

What maintenance routines keep the Amita 4 4113‑093‑11A performing?

Routine cleaning and inspection are critical. After each use—especially in saltwater—rinse prop with fresh water to eliminate corrosive salts. Inspection for nicks or bends prevents imbalance issues. Apply marine grease regularly, and annually remove the prop to look for fishing line around shaft seals. Address minor dings by smoothing with a fine file or consult propeller repair services for larger deformations.

Balanced blades and clean paddles maintain thrust and efficiency. Following these topic maintenance tips ensures fuel savings and extends the lifespan of the prop over many boating seasons.

How durable is the aluminum in Amita 4 propellers?

Solas uses squeeze‑cast aluminum—this casting method yields denser, more uniform material than traditional sand casting, reducing microfractures and improving mechanical strength. Coated with a corrosion‑resistant powder finish, the Amita 4 prop resists saltwater and freshwater deterioration. With proper care, users often enjoy over 500‑600 hours of service before significant wear. Regular inspections for erosion or pitting are recommended.

Aluminum remains lighter and more forgiving than stainless steel and provides reliable service in recreational boating environments. If you frequently encounter submerged debris or hull strikes, consider inspecting more often or pairing with a guard to protect blades.

What is the expected lifespan and cost‑benefit of this propeller?

For boaters who maintain cleanliness and perform annual service, the Amita 4 4113‑093‑11A typically lasts for 4‑6 years or up to 600 hours of use. Its durability and performance upgrade justify the initial cost, especially compared to stock props that often under‑perform.

Factoring in reduced fuel consumption, improved acceleration, and less engine stress, the total cost of ownership becomes favorable. Add the 5% discount with code WELCOME5 and expected longevity makes this model a high value proposition for marine propulsion upgrades.
