Got PP Stargazer installed by myself. Thanks to the maintenance section it was pretty straight forward even for a non mechanical person like me. I followed the directions except that there is no requirement for a paddle wheel so no drilling required! I made a small mount for the GPS antenna when I was switching out the dash panels.I took her out for a short shakedown cruise today and it worked very well. I could not be more pleased with the speed control and the large display.
