Thanks James

Wish I could figure out this board.
I can't see my original thread.
Picture was too large so I re-submitted smaller but
it looks like I'm in the dog house.
Too bad cause the crane is coming and I'm running out of time.
Cheers

JB

Hi James

Thanks for reply.

To remove the Echo Sounder Transducer, do I remove the circlip on the top
(inside the hull) and yank?

Is the transducer housed in a tube of some sort, i.e the blue cylinder we
can see in  the pic?

Much Obliged
