Re: Airmar / Raymarine DST800 Transducer Issue
I never would have thought that there are boat owners out there who regularly remove a transducer while their boat is in the water. have the same DST800. It has been in salt water for over four years. The only time it has tasted oxygen is the last haul/bottom job two years ago. It has never failed to work. Call me crazy but it seems like each time you open a hole in the bottom of your boat there is a potential for something very bad to happen. I would think the only reason you should remove it while the boat is in the water is if it stops working. You can clean any gunk or replace the paddle wheel. I am in the insurance claims business and this sounds suspiciously like the beginning of a loss report.
"I thought I'd make a video of how high the gusher is when I remove my speed transducer and..." Water cooler stories for weeks.
The flapper is a gimmick. I would never even think to trust it.
