Very satisfied with Dolphin fin

The Fin is installed on a 19' high profile boat with a 25 horse 4-stroke. It was easy to install and works very well. The turning radius is shorter and low speed steering is much improved. The boat has a significant keel so the fin adds lots of turning power. There even is some steering control when in neutral. The fin is invaluable in wind and in docking.
