Re: Problems with my nx882...
I think this info will help you out:
For safety, and efficient performance, it is critical that your engine operates within the RPM range recommended by the manufacturer.
A change in the prop pitch will increase or decrease the engine RPM's and can be used to bring them into the recommended range. A 2" pitch increase (for example, from 21" to 23") will result in approximately a 300-400 RPM decrease and vice versa.
The correct prop allows the engine's RPM to run within the top end of the manufacturers recommendation.
3 vs. 4 Blade Props
3-Blades
3-blade props are great on most boats as they offer good all around performance, better efficiency, and can achieve higher speeds. Switching from 4 to 3-blades generally requires a 1" pitch increase.
4-Blades
4-blade props work well with bass, pontoon & high performance boats as they provide better acceleration (hole shot), keep a boat on plane with fewer RPM's, and produce less vibration at high speeds. Switching from 3 to 4-blades generally requires a 1" pitch decrease.
