Prop Diameter
![Prop fit on the boat is not affected by diameter](https://www.iboatsimages.com//mall/image/propfinder/info/help-diameter.gif)
Diameter is the width of the circle that the prop would make when rotating.
Prop diameter does not affect the fit of the prop on a boat.
The diameter of your prop can vary by up to 1/2" with no discernable change in performance.
Caution: Before increasing the diameter of your prop, make sure there will be enough clearance between the blades and cavitation plate or anode on your engine.

2-Piece Props
2-Piece propellers consist of the outer prop housing and a removable center hub.
The removable hub easily slips into the outer piece, allowing you to have multiple props for different applications at a lower price. When the prop blades become worn or damaged they can be replaced while keeping the same hub piece.
2-piece propellers perform the same as the 1-piece/fixed hub versions.
Prices listed include both the housing and appropriate hub.
Both parts are added to your cart making it easy to find your complete propeller.
