I just acquired a beautiful 1996 SRV270DA Sundancer. Beautiful boat with almost every option available including the 7.4 liter with a Bravo III drive. The drive experienced a major "OOPS" during trailering when the drive "somehow" went to the full-down position (that's the story I was told, anyway). Everything below the lower bevel gear was ground off. My dilemma: Used Bravo III lower units are hard to find, and new ones are $$$. New and used Bravo I lower units are everywhere and can be had for less than $1000. My question to everyone is - what are the pros and cons of spending the money to keep the Bravo III vs. saving the bucks and installing a Bravo I?
