Know that you need exactly the right propeller if you are keep the engine of your boat a longer life and best overall performance. Note that you may have to change the propeller if you change the way you use your boats and boat engines. Using a wrong propeller will not only affect the performance of your engine but can destroy your engine too in no time. Learn the most important lesson about boat propeller, see page now.
Generally, boat dealers will have matched the propeller to the engine, if you are buying as a combined package your engine and boat, and this is part of the pre-delivery rigging procedure. It is therefore important that you verify this condition with the dealer. However, as you own the boat, you may be adding heavy items that could affect the choice of the propeller, given the fact that the dealer had already pre-selected it based on the average load of your boat. All of your question about Propeller Depot will be answered when you follow the link.
Things and situations like outboard powered houseboats, pontoon boats, towing water skiers, are examples that will accumulate heavy gear and will affect the performance of your propeller. Or maybe the original purpose of your engine is for a small sailboat but now you are using it as the primary propulsion for lightweight skiff. Maybe you are fond of visiting mountain lakes of which the extreme changes in altitudes can affect the operation of the engine. All of these mentioned will re-propping then to maintain a good performance of your propeller and consequently your boat.
It is also good to know some basic terms or terminology about your propeller. One is the pitch, of which is described as the theoretical distance in inches in one complete revolution as the propeller moves forward or backward. Next is the diameter, which is the straight line distance from the center point of the hub to the outermost point of any of the propeller's blades multiplied two times.

Next term is cupping which is described as the curl at the trailing edge of the blade of the propeller. In order to have a better grip on the water, engineers used cupping to increase the theoretical pitch of the blade. Related to the pitch is the slip, which is the theoretical distance of which the propeller will move through the water for every revolution. This is affected with the situation when the propeller will actually lose some distance as it slips through the water. The thickness of the blade is the guiding factor of which the design of the propeller and the material used is determined.
