Pitch – the theoretical distance in inches that a propeller moves forward in one revolution. Think of a screw in wood. If you increase the angle of the threads, it will move further into the wood in one turn. Diameter – the diameter in inches of the circle that..
We can help you select the correct propeller the more info we know the more accurate our recommendation Motor type and manufacturer Year and horsepower of motor Length and type of boat Any current prop info will help. Diameter, pitch and type of material WOT (wide open throttle) RPM..
Start of the boating season 2019 for those of us who experience a winter! A lot of us are waiting for the nicer weather to show up! Record rainfalls, lots of flooding and swollen riverbanks has delayed some of us from safely accessing launches. The nicer weather is coming..
Courtesy on the Water. For all of us to enjoy our boating experience, courtesy and the rules of the waterways are extremely important. From kayakers and canoers, to the fishing boats to the cruisers and the sailers, knowing when to give way, when to slow your boat down to..
The Piranha modular design allows for blades to be replaced due to damage or to be re-pitched for performance. The key to the patented Piranha boat propeller is the hub. The center hub is made from a high-strength aluminum core, over molded with our specially-formulated composite material. The Piranha..
Another title could have been Boat propeller Diameter on command trust or big foot motors. Many factor will influence rpm and diameter is one of them. I am seeing in the last several seasons some large pontoons being pushed by 60 hp engines that are command trust /or Bigfoot...
Of course! All propellers flex. What is often missed is that flex is a good characteristic. For example, if a prop flexed under the load of acceleration, it would actually be reducing its pitch, which in turn would produce a faster acceleration. A problem would occur only if the..
Boat propeller advice First the best way to improve performance is with the correct propellers. You can try all kinds of different props with different types of blades styles and cupping and diameter and weight in the boat and water and wind condition and you will always get a..
There are many factors that can cause a boat to have difficulty coming onto plane. Consider for example, your total boat weight, weight distribution, engine trim, hydrofoil, and transom tabs before investing in a new propeller. To assist in the correction of on plane problems, you may also need..
Have you ever run your finger along the face, or edge, of a prop and felt a pitted area? If you have, then you know what cavitation can do to a prop. Given enough use, that pitting will only get deeper and you will end having to replace the..
Most small dings or bends in an aluminum prop can be repaired for a reasonable price. If you do repair, make sure the shop does not file down the blade edges thereby reducing diameter. If your damage includes bites or chunks out of the blade, you should consider a..
I advise boaters to spend as much as it takes to get the right propeller for their boating application. Don’t be too concerned with prop costs because the biggest bang that you can get for the buck, when it comes to boat performance, is with the propeller. Remember that..
