(M4W) Finding The Right Match Between The Propeller, Engine Type And Boat Size Will Optimize The Following Performance Factors: • Increased Top End Speed • Faster Planing Speed (Hole Shot) • Improved Low End Punch • Load Carrying Capability 3-Blade Propeller vs. 4-Blade Propeller We recommend 3-Blade propellers for recreational boats with 3, 4, and 6 cylinder outboards and I/O engines. These propellers provide good hole shot and top-speed performance. We recommend 4-Blade propellers for practical, all-around boat performance. These propellers enhance handling, hole shot, load- carrying performance, and fuel efficiency. Most pleasure boats are factory equipped with aluminum propellers. Aluminum propellers are relatively inexpensive, easy to repair, and under normal conditions can last for many years. Stainless steel is more expensive, but much stronger and durable than aluminum. If you are looking for better performance than can be provided by your aluminum propeller, such as ultimate top speed or better acceleration, a stainless steel propeller may be required. Aluminum vs. Stainless Steel Pitch is defined as the theoretical forward movement of a propeller during one revolution - assuming there is no “slippage” between the propeller blade and the water. For most boats, there is slippage and therefore the distance advanced is less than the design pitch. The amount of slippage varies from boat to boat. Pitch is the second number listed in the propeller description. Pitch Cupped Uncupped Many of today’s propellers incorporate a cup at the trailing edge of the propeller blade. This curved lip on the propeller allows it to get a better bite on the water. This results in reduced ventilation, slipping, and allows for better hole shot in many cases. A cupped propeller also works very well where the motor can be trimmed so that the propeller is near the surface of the water. The cup will typically result in higher top end speed on one of these applications. Cupping Diameter is two times the distance from the center of the hub to the tip of the blade. It also can be looked at as the distance across the circle that the propeller would make when rotating. It is the first number listed when describing a propeller. Diameter Chaos propellers are designed and manufactured to provide smooth performance and maximum thrust for a wide spectrum of Tow & Ski water sports applications, whether it be wakesurfing, wakeboarding, or water skiing. Each Chaos propeller has been expertly manufactured in the USA.
