Propellers have two basic dimensions; diameter and pitch. Diameter is the distance measured across the propeller hub line from the outer edge of the circle that is made by the propeller's blades during rotation. Pitch is the distance that a boat will travel if rotated one revolution without any slippage. When describing a propeller both the diameter and pitch are given. The diameter is referenced first and the pitch is second. Therefore, a 12" x 9" propeller would have a 12-inch diameter and a 9-inch blade pitch.
Theoretically, a propeller with a 14-inch pitch, when rotated one full turn, would advance a boat 14 inches through the water. In reality, no 14-inch pitch blade will advance a boat 14 inches with one full turn. This variance is referred to as slippage.
In general, changing to a higher pitch prop will increase your top-end speed but reduce your acceleration (reduce your "hole-shot" power). On the other hand, decreasing the pitch will increase your hole-shot but sacrifice some of your top-end speed. If the hole-shot speed is important to you, for example if you pull water skiers most of the time, then you would want to go with a lower pitch prop and sacrifice some of your top-end speed but increase your hole-shot speed to get the skiers up faster.
The propeller selection chart can be used to help you in selecting the correct propeller for your Tohatsu outboard. Remember that in any application, discrepancies in performance can result due to the different boat hull designs, the final carrying load and your particular needs.
This information is critical to determining the correct propeller for your application:
A 3-blade propeller usually offer s top speed performance.
Diameter is the distance across a circle encompassing all of the propeller blades.
Pitch is the theoretical distance a propeller will move through the water of each revolution.
4. Right hand or left hand Rotation
In most cases, right hand propellers are used for single engine application and one left hand propellers are used for twin engine applications to achieve better steering control.
5. Cupped Blades:
This is a technique used to enhance the performance of propellers under certain conditions. A cupped propeller will exhibit very high efficiency at high speeds as well as minimize cavitation under heavy loads.
Rake is special design feature. Positive rake benefits from normal bow lift to permit the use of a larger diameter propeller, while negative rake can provide extra blade strength for use in very high speed applications.
