Best Boat Guide

Gone are the days when people highly relied on paddling to make their boat run because modern boats already have propellers in them. A boat propeller is a device used getting your boat to move around in water.

Propellers work by rotating 3 to 4 blades that are twisted with a shaft that is similar to a screw's rotation. Most blades are made of stainless steel or aluminum for durability and for corrosion or rust resistance. Boat propellers also work by providing a difference on the pressure between its back and front surfaces. As their wings rotate, the type of force explained by Newton's Third Law and Bernoulli's principle is applied.

However, propellers cannot work without the motor so you need to make sure that you have one. In this boat propeller guide, you can learn more about them so you know how to buy the right one for your boat.

Boat propeller guide: the designs

There are two types of boat propeller designs to choose from - the three-blade design and the four-blade design. The former is actually the most common design among propellers because it offers better acceleration and good control. On the other hand, the four-blade propeller design is usually found in stainless steel variants and never aluminum. It offers better hole shot, higher trim angle, and better bow lift to avoid dragging. Four-blade propellers also allow your boat to stay on the plane even with low rpm (revolutions for minute), and it also gives way to slow cruising speeds without resorting to loss of plane in rough waters and weather conditions.

Buying tips in the boat propeller guide

When choosing among boat propellers, select one with a pitch that has an inch of reduction to produce an increase of 150 rpm to 200 rpm even at full throttle. More importantly, make sure that the propeller is compatible with the engine of your boat. Check for recommendations by the manufacturer of your boat engine. A serial number or the size of the propeller can be found in the hub or in the manual.
