It was suggested on the humminbird forum that I ask here as well. Hight speed is with a thru hull so no need for the transducer to be in the water while on plane.
I am mounting an SI transducer on a 2006 Ranger 519 using a transomeshield jackplate mount onto a Bob's 6" plate. I cannot seem to find any specifics on the mounting height for the transducer relative to the hull step. On the 6" plate I need to drill all the mounting holes so I don't have a reference to start from. Do I need to be below the level of the hull step or can I be slightly above it to give the transducer a little better protection? If above the hull step, how high is too high?
Thanks much,
Joe
