Prop Shopping: The Right Choice for Your 90HP Mercury 4-Stroke
Buying a new prop for your 90HP Mercury 4-stroke engine is important. You want the best performance. This guide will help you choose the right one.
Key Features to Look For
- Diameter and Pitch: This is super important! The diameter is the prop’s width. Pitch is how far the prop moves with one turn. Your engine’s performance depends on these numbers. Check your engine’s manual for the recommended range.
- Number of Blades: Props come with 3 or 4 blades. Three-blade props are usually faster. Four-blade props often give better acceleration and grip.
- Material: Props are made from different materials. This impacts the prop’s performance and durability.
- Ventilation: Some props have ventilation holes. These holes help with quicker acceleration.
- Hub Design: The hub connects the prop to the engine. Look for a hub that can handle the engine’s power.
Important Materials
- Aluminum: Aluminum props are the most common. They are cheaper. They are a good choice for general use. They can bend easily if you hit something.
- Stainless Steel: Stainless steel props are stronger. They give better performance. They cost more than aluminum. They are a great option for speed and durability.
- Composite: Composite props are a newer option. They are lightweight. They can offer good performance.
Factors That Improve or Reduce Quality
- Manufacturing Process: How the prop is made matters. Precision manufacturing leads to better balance and performance. Look for props made with good quality control.
