It is important for you to have the right boat propeller in order for your boat to have a long engine life and great overall performance. But there is always no right boat propeller. If you want to change the way you will be using your boat and boat engines, then you also need to have some changes on the boat propeller. The performance of your boat will not only be affected with the wrong boat propeller, but your engine will also be damaged fast.
You will also get the boat propeller from the dealer as part of the pre-delivery rigging process if you will buy a boat and boat engine as one package. But you should verify this with the boat dealer. But there might be some changes if you own the boat. The boat dealer will select the boat propeller depending on the boat’s average load. But you might add heavy items that will affect this important aspect in choosing a boat propeller.
The pontoon boats and outboard-powered houseboats are some of the boats that can accumulate heavy loads. Great changes in the altitude will be affecting the operating range of your boat engine. If your boat engine is made for sea level, you will need to have a different boat propeller for high-altitude operations in order to keep the engine revving in its normal range. As a matter of fact, you will need to re-prop for these changes.
The goal of changing some parts of the engine is to make sure that the engine will reach a certain rpm. The top speed of the engine will range with an 800 to 1000 rpm.
In order for you to understand the topic clearly, you need to make sure that you will take note on some other terms about the boat propeller.
Pitch – this refers to the theoretical distance that is covered by the boat propeller in one whole revolution.
Diameter – this is the doubled straight line distance from the center of the hub to the tip of the blades of the boat propeller.
Cupping – refers to the curl found at the trailing edge of the blade of the boat propeller. This is used by engineers to increase the pitch of the boat propeller blades in order for it to have better grip on the water.
Slip – this is associated with the pitch. The distance that the boat propeller will be moving in one revolution will be affected by the fact that it will be losing some distance because of some slippage. A standard boat propeller will usually have 10 – 30 percent slip based on its use and design. You can visit this link to know more about boat propellers.
