I have Autoprops on a 42' Lagoon and am very pleased. Replacing two blade props, these have the same thrust in fwd and rev. Really handy when backing down on a following breeze or current

that maintains maximum efficiency at all times. It has a higher efficiency over a wider range of RPM
settings, producing higher speeds with lower engine
