Hi
I’ve had a new DTS800 speed/depth transducer fitted but with the yellow ‘O’ ring fitted it does not fit flush in the thru-hull fitting which has a flap valve. It’s screwed down tight.
I’ve tried the black ‘O’ ring, it fits flush but it then leaks.
The transducer and yellow ring are well lubricated with the lube provided.
Does anyone know how to get the transducer to sit flush in the housing?
Regards
Brian

Dear Bradley,

Thank you for your post.

Can you please follow the documentation on the insert of the DST800. the bulletin from Airmar can be found here.

Many Thanks
Louise

Thanks Louise
I’ll take a look at this on Monday with the engineer who did the fitting.
However, I wonder if as the bulletin is still valid as it’s from 2005 and 14 years old!
Thanks for the advice.
Brian

Dear Brian Bradley,

Thank you.

It is good to confirm that all of the correct steps have been followed.

Many Thanks

Hi Louise

It appears that the strong arm of the engineer was required to put another three turns on the transducer fitted get it seated properly in the housing.
So it’s now sorted.
The yellow o-ring and a good hard screw down we’re needed.

Brian
