If you want to have a longer engine life and better boat performance, then you need to have the right boat propeller. But you need to know that there is no boat propeller that is always right. 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. It will not only be the boat performance that will be affected by the use of the wrong boat propeller, but the engine of your boat will also be damaged quickly.
If you invested on a boat and boat engine as a package then the dealer will be matching it with the boat propeller for the pre-delivery rigging process. But it is important for you to verify the dealer about this. But if you own the boat, there might be some changes. The boat propeller will be chosen depending on the average load of the boat. But every time you will add heavy items, this aspect of choosing a boat propeller will be affected.
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 is made for sea level operations, then you need to look for the right boat propeller if you will be using it on high-altitude lakes so that the engine can run within 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 tolerance of the top speed of the boat engine will fall under the range of 800 – 1000 rpm.
There are some other boat propeller terms that you need to take note of in order to understand more about this topic.
Pitch – this refers to the theoretical distance that is covered by the boat propeller in one whole revolution.
Diamater – this term refers to the straight line distance of the center point of the boat propeller to the edge of the blades multiplied to two.
Cupping – this is the curl at the trailing edge of the boat propeller blade. 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 connected to the pitch. The distance that the boat propeller will be covering in one revolution will be affected because of the slippage on the water which is the cause of the boat propeller to lose distance. A standard boat propeller will usually have 10 – 30 percent slip based on its use and design. Click here for more info.
