Re: Airmar / Raymarine DST800 Transducer Issue
My understanding is that Airmar is responsible for warranties on their equipment. My replacement thru-hull came from them (of course it performed no differently), so I would suspect that yours would too. My installer told me that the only way to prevent valve detachments is to lubricate the transducer and plug o-ring thoroughly and frequently. Something about dry o-rings gripping the flapper and pulling it loose from its hinge pin.
Hope you have a great sail on Sunday.
