Propeller Characteristics - Spline Count
Count the teeth on your prop shaft or inside the hub to determine spline count.
Spline Count
Spline Count is an important factor in fitting a prop. They are the little teeth you see on your propeller shaft and inside the hub.
The number of splines on the shaft and inside the hub must match for the prop to fit your boat.
A Pin Drive application has no splines. The prop is secured to a smooth shaft with a pin through the shaft.
