INTRODUCTION

• To enhance the performance of the boat you must
  use the right propellers.
• A boat propeller is a mechanical device with
  shafts having angled blades fixed in it.
• The change from rotational motion into thrust
  generates power.

THREE BLADE AND FOUR BLADE PROPELLERS

• Three blade propellers are most commonly used and
  it is made of aluminum.
• The propeller and boat engine are connected with
  the help of this holeshot only.
• One of the benefits of four-blade propeller is it
  can maintain its steadiness at any speed which is
  not possible in three blade propellers.

5
FIVE BLADE AND SIX BLADE PROPELLERS

• Five blade propellers have better holding power
  and therefore, this can be the best option for
  traveling in rough seas.
• Manufacturing this type of propeller is costlier
  than others.
• The propellers induced pressure field can be
  reduced in this six-blade propeller.

6
FIXED PITCH AND CONTROLLABLE PITCH PROPELLER

• During the working of the boat, the pitch in the
  fixed pitch propellers will not change since the
  blades in it are fixed to the hub permanently.
• This type does not require any mechanical or
  hydraulic connection therefore, they are robust
  and reliable in nature.
• Not as in fixed pitch propeller, in controllabsle
  pitch propellers pitch can be modified
  accordingly.

CONCLUSION

• For having your boat without any troubles and
  repairs, you should clean your boat frequently.
• During underwater maintenance, propellers need to
  be checked carefully.
• A damaged propeller can affect the performance of
  your boat.
