Had a 106 for two years now, if had to replace it might go different route but very pleased in general and I feel like I’ve been lucky given the problems many have had. But my goal was to raise the unit to get an expanded view. Is a 10” raised 18 inches as good as a 12” sitting closer to the deck? But one caveat, consider if you are restricting your view while running. Am really concerned with all the paraphernalia that is on some boats, always gives me pause when meet one in a narrow area.
