I remember grounding the transducer to the negative on the battery. 

I did notice that the instructions say to paint it. Is that to insulate it from the saltwater?

I think I would be engaging Alan as a consultant after the awesome job he and Mark did on his.

Thanks for the kind words Greg.  :smile1:  Sounds like Shawn has things well in hand. And it is an entirely different procedure. About the only thing that is the same is gooping sealant/adhesive all over the place.  :hoboy:

Besides, none of our tubs are likely to get close to 50 MPH on the ocean.  At least not often enough to worry about it.  Most of us are really happy to make 35+/- on our best day   :biggrin:

Throw in a little chop and we all slow right down....
