PROPELLER AND PROPELLER SELECTION :
The performance of a propeller has a direct effect on that of both the boat and outboard motor. It is safe to say that the propeller greatly affects the boat speed, acceleration, engine life. fuel economy, and even boating and steering qualities. Therefore, the selec- tion of the right propeller for the user’s boat is of vital significance. FUNCTION OF THE PROPELLER: As the propeller turns. a negative pressure is created on the aft surface of the propeller blade and a positive pressure on the back of the blade.
- This produces the thrust required to move the boat ahead. The point is, how- ever, that the same propeller can never serve well for different types of boats. in order to bring boat performance into full play, it is necessary to select the right propel- ler for the specific use being made of the boat, such as water skiing. cruising, fishing, racing, etc.
- When a boat has to be used for various purposes, several different types of propellers will be needed. In addition, the material the propeller is made of and where the boat is used le.g., rivers, seas, shallows, rock-bound waters, etc.) are also important.
- Whatever the purpose of the boat, always make it a habit to carry spare propellers and hand tools. in case of heavy propeller damage, you will be able to rely on the spare propeller to enable your boat to sail for a nearby port.
