Detailed FAQ Section
1. What is the pitch and diameter of the Amita 4 – Tohatsu/Nissan propeller?
The pitch is 12 inches, and the diameter is 10.8 inches. These specifications are essential for achieving optimal performance for boats using Tohatsu or Nissan outboards. Pitch determines how far your boat moves forward with one full rotation, while diameter affects the overall thrust and torque. This specific configuration is ideal for moderate to heavy loads, allowing better grip in rough waters and improving acceleration and control.
2. Can I install this propeller on a different brand engine?
While primarily designed for Tohatsu and Nissan outboards, it may fit other brands if they have compatible spline count and shaft size. However, using it outside its intended fitment may result in performance issues or mechanical mismatch. It’s highly recommended to consult with a marine technician or refer to compatibility charts before attempting cross-brand installation.
3. How do I know if this propeller suits my boat’s needs?
If you’re experiencing sluggish acceleration, poor fuel economy, or issues with planing, switching to a 4-blade prop like the Amita 4 may help. The 10.8 x 12” size is ideal for mid-range cruising, fishing, and water sports. It provides better hole shot, increased lift, and stability without compromising top speed drastically. For accurate selection, match it to your engine’s RPM range and your usual boating conditions.
4. Is aluminum a good material for marine propellers?
Yes, aluminum—especially squeeze-cast, like in the Amita 4—is an excellent material for marine propellers. It’s lightweight, cost-effective, corrosion-resistant, and easy to repair or replace. Compared to stainless steel, aluminum props are more affordable and ideal for casual to moderately demanding marine use. Regular inspections and freshwater rinsing after saltwater exposure can significantly prolong their life.
5. What is the average lifespan of this propeller?
The lifespan depends on usage, maintenance, and water conditions. On average, an Amita 4 aluminum propeller can last 3 to 5 seasons or more with proper care. Avoid hitting submerged objects, rinse after every trip, and periodically reapply grease to the shaft. Replacing a worn or damaged prop promptly can prevent further damage to the engine’s lower unit.
