Randy, Touche's speed transducer is located under the step for the V-berth forward of the keel. Really. I have to reach through an inspection port to remove it. I wanted it well forward in undisturbed flow.
Personally, I'd drill a new hole forward of the keel and fill the old one. 4200 or 5200 works. -- Dennis C.
