Over the last six months we have been working really hard developing some propellers to work on the Bravo III and Yanmar ZT350 drives. I drove out to Parker to test the final set out this week and was so impressed with the results that I couldn’t help but share them with everyone. The front and rear propellers tested were all the same pitch as the OEM propellers, so it wasn’t like we put on 26’s against the stock 24’s.

The boat tested was a 27’ with a 502” motor and a Bravo III drive. The planing time of the two sets were about the same, however their was a clear difference in the smoothness of the Four By 4’s versus the stock three blades.

Below are the results of the final set we are going to put into production against the stock Mercury propellers as well as some pictures. Production is set to begin mid August.
