LH rotation Mercury Alpha-4 Prop.

4-Blade Aluminum prop, 15 x 16 (diameter x pitch)
(replaces a 3-blade aluminum 15x17 prop)

Hub installed, Hub hardware included.

Prop never used (I ordered the LH instead of standard rotation accidentally)

Note:  When I installed the proper rotation version of this prop, my cruising speed increased by 3 mph at the same rpms.  Note, I used the identical prop, only the correct rotation, versus the LH (single engine boat) for the below.  Your improvements to performance should be comparable:
Was: 18 mph @ 3,300 rpm
Now: 21 mph @ 3,300 rpm

Holeshot noticeably faster.

From the manufacturer's website:
"Alpha 4

The Alpha 4 aluminum propeller provides four-blade performance and acceleration at an affordable price. The Alpha 4 is an outstanding propeller for stern drive-powered runabouts, as well as cruisers. With an Alpha 4, your boat will get on plane quicker and stay on plane at lower speeds than with a comparable three-blade propeller. The Alpha 4 is also an excellent water sports prop.

  • Available in 16-, 18- and 20-pitch
  • Right-hand and left-hand rotation
  • Fits outboards (135hp and above), Alpha and Bravo One stern drives
  • Recommended for inline 4, V6- and V8-powered stern drives.

Video: FiDU technology creating lightweight, inflatable metal structures

Mon, 30 Apr 2012

This short video, featuring designer Oskar Zieta, details the process and design possibilities behind products developed with FiDU (Freie Innendruck Umformung – "free internal pressure forming") technology. Zieta, a Polish designer, explains how the lightweight yet robust metal appears as a soft object yet when you touch it you realize that it is actually a hard metal. "Working with FIDU technology is similar to carving clay," Zieta explains.
