Three Blade Aperture 'A' (APA)

JBC Engineering

Made for the traditional full-length keel market, the APA was designed to increase performance where other props couldn't fit. While it comes with a larger diameter hub, it has a hub length of only 82mm, making it perfectly suited to older yachts. Launched in 1992, on the two time Hobart winner, Margaret Rintoul, the APA has been one of our best sellers ever since.

The prop can be counter bored for nut to suit a shorter taper if required. 

Can be set up for right hand or left hand rotation.
