Doing Boats The Right Way

A Boat Propeller Buying Guide

The selected boat propeller determines how well a boat shall perform. When choosing a boat propeller, you have to keep certain things in mind. These are its size, number of blades, the material it is made out of, its RPM at the wide open throttle, and the use of the boat.
The prop size emerges as the most important consideration. Choosing the wrong size often leads to a damaged boat and engine. You need to look at the boat prop’s diameter and pitch when gauging its size. The higher the pitch, the more speed the boat shall manage, given it has a powerful engine. Its larger diameter means it will accelerate faster.
When it comes to blades, you shall find three to five ones. The more the number of blades, the more performance it can deliver. The lesser the number of blades, the more top speed it can reach. This explains why most racing boats have three bladed props. If it is cupped blades, even better. Cupping refers to the curve at the end of the blade, which essentially helps it turn sharper. You need to also think of the rake of the blade. The rake is the angle the blade makes with the prop hub. It is there to keep slipping away.

You need to also be keen on the material used in making the boat prop. Aluminum props are easily found and are cheaper. They make for lightweight and strong props. Their drawback is their inability to survive salty waters. Stainless steel props are the better option there. You will have to spend more on those blades though. They also present the danger of damaging the entire engine system, which is not the case with aluminum props. There are also composite and plastic props, which serve their purpose well in case of an emergency.
Your boat also has a specific RPM at wide open throttle range rating it can work with. You shall find this info in the manuals.

You need to also factor in the use of the boat in your selection. You shall find a wide variety of props, each serving a specific purpose. Some are ideal for pontoons, bass boats, and skiing boats, those for fishing, racing, or relaxation. There is also the thought of the kind of water the oat shall be traveling on. Some props are great for lakes, while others are ideal for rivers or slow-moving waters. Others are meant for the high seas. Some are specially designed for flat, heavy passenger or goods boats. This means that your choosing has to consider such differences. It is wise to invest in an extra prop, for those times and emergency crops up.
