Re: homemade Sternmate (no hole transducer attachment)
Its made of .10 aluminium. I set it 1/4 inch above the bottom of the boat. The seam in the transducer sets dead even. Its a little close to my prop (13 inches), so i get a small amout of grey wash on the screen at full speed. I couldn't go the 15 due to the design of the strakes on the bottom of the boat. The bracket kicks up a small rooster tail. I will have to make a cover for the bottom to smooth things out. It worked well and just needs some minor tweaking.
