i have ran my trs drive into reefs or objects three times in the last 12 years and it's no fun!!
really have to watch out and hard to trust charts or gps when you know you are in skinny water, best to avoid water less than 6 feet and that's a calm measurement for me.
sorry about your luck, evidentaly you will have to get used to a rig with more draft
the "trailer" button and idle speed are your friends here
my insurance co. paid for the last one because it ruined the housing and the main shaft not to mention the prop at 600 bucks
never had these issues with my inboard lyman!....
