How To Choose The Right Boat Prop

How To Choose The Right Boat Prop – Prop Bite: Prop Diameter and Blade At its simplest, a boat propeller is simply a propeller that moves through the water. To better understand how this rotation works, let’s define the two main dimensions used to describe all supports: diameter and axis.

You will usually find these specifications printed on the hub or barrel of a boat propeller. For example, a fan marked 14 x 19 has a diameter of 14 inches and a pitch of 19 inches, usually in that order. Let’s define these terms.

Screw diameter is relatively easy to understand – it is simply the diameter of the circle that the blade makes as the prop rotates. Imagine attaching a pencil to the tip of a knife and pointing the support at the paper. It draws a circle representing the rotation of the propeller. The diameter of a circle is the length of a straight line passing through the widest point of the circle.

How To Tweak Your Props To Make Your Boat More Efficient

Screw engineers determine the diameter of the strut to determine the rotational speed of the strut and the force it delivers to the strut. The diameter is usually larger for propellers used in slower, heavier boats and smaller for propellers designed for faster boats. Larger diameter props have a larger overall blade area and can handle more force and generate more power to propel a heavier boat. More blade area makes the engine “pull” more like an aggressive truck tire. But as with these bubbles, the additional diameter creates more drag, which increases as the boat accelerates. Designed for the heaviest recreational boats, the MerCruiser Bravo two-axle can use propellers up to 20 inches in diameter, while the Bravo One Super is designed for faster speeds in light cruisers, and the current largest outboard is 16 inches. .

Pitch is often defined as the theoretical distance traveled by the software in one revolution. Consider turning your nose into a wine glass or a frying pan. Our 14 x 19 props advance 19 inches per turn. A 14 x 21 moves 21 inches per revolution, so it does more work and moves faster than a 19-pitch prop at the same RPM. Some models of Mercury fans are one-inch and others are two-inch.

Changing the position of the throttle is like changing the gears of a bike up and down – you can go up and down in a low gear, but soon your legs will spin and you won’t go very fast can’t drive In high gear you have to press the pedal to start moving, but you will eventually get to a faster speed. All else being equal, in a wide-open (WOT) engine, adding fan noise reduces engine speed, while removing pitch increases WOT RPM. If the prop pitch is too low, the wide open engine RPM can be too high (higher than the engine’s recommended WOT RPM range) and the boat’s top speed will be lost, even with strong acceleration. If the throttle position is too high, acceleration will suffer and the engine will “squeeze” or not reach below the recommended WOT RPM limit. Either condition – too high or too low WOT RPM can damage engine and drivetrain components.

As Mercury engineers determine the appropriate diameter for the pitch, the general design of the fan and the intended use of the fan, the line diameter of the fan model may vary slightly within the range of pitches. So different propeller models can have the same pitch but different diameters – for example, the Mercury Spitfire® X7 is 13 x 17, but the Mercury Cup Plus is 13.75 x 17. There are dozens of variables. Each propeller has its own style, but for most boat owners, just paying attention to the design and optimal pitch will make a Mercury propeller a good choice.
