A Boat Propeller Buying Guide

your propeller choice has a lot of significance to the boat’s performance. When choosing a boat propeller, there are some things you have to consider. You need to think of 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 has been found to be the most important thing one thinks of. Choosing the wrong size often leads to a damaged boat and engine. You thus have to consider the boat prop’s diameter and pitch when measuring its size. With a powerful enough engine, a higher pitch would gain the boat more speed. Larger diameters in the other hand give the boat faster acceleration.
When it comes to blades, you shall find three to five ones. A higher blade count means the boat shall manage even better performance. The fewer the number of blades, the more top speed it can achieve. You will thus see most racing boats with three bladed props only. Cupped blades are even more preferred. Cupping refers to the curve at the end of the blade, which essentially helps it turn sharper. The rake of the blade is also a consideration here. The rake is the angle the blade makes with the prop hub. Its the purpose is to prevent slipping.

You need to find out what material was used to make the prop. Aluminum props are readily available and cheap. They are lightweight and tough. Their drawback is their inability to survive salty waters. Stainless steel props are the better option there. Those are not as cheap. They will also damage the engine system in case they hit an obstacle, unlike the safer aluminum variety. You will also find composite and plastic props, which are ideal for emergencies.
When choosing the ideal RPM rating, you need to look at what is recommended for the boat. You only need to read about it in the manual to make the right selection.

You need to also factor in the use of the boat in your selection. There are many prop types out there, meant for different uses. You shall find some designed for pontoons, bass boats, and skiing boats, those for fishing, racing, or relaxation. You also need to think of the water on which the boat shall be. Props used on lakes, and on rivers, and even on slow moving waters are not the same. You will find a selection meant for the high seas. Some are specially designed for flat, heavy passenger or goods boats. There are all manner of uses for these props, which must be factored in the purchase. It is also important that you buy an extra prop in case of an emergency.
