Please Help: I own an Edgewater 225 Center Console with a 20 degree transom angle. My electronics include the Furuno FCV 587 with an Airmar 525STID-PWD (P-66) 600 W Transom mount Transducer (new since Mar. 2013)
All functions on the FCV 587 work great except, when going about 20-25 MPH, I am getting "Breaks" (gaps) in bottom indication. The faster I go the more "Breaks" (gaps) I see. When going slower than 20 MPH, the "Breaks" in the bottom are minimal.
I have pictures of the current position of my Airmar Transducer. I can send them if you need them. In talking with the technicians in Denton, MD, they suggested I take measurements on the hull of my Transducer and contact the Sonar expert through the Forum.
Measurements are as follows:
[*] Prop hard to STB - Prop swing radius to the left edge of Transducer is 4.75 inches NOTE: When the engine is straight, the swing radius of the prop to the left edge of the Transducer is 8.5 inches.
[*] Bottom of Keel to the Left edge of Transducer is 18.75 inches.
[*] Left edge of Trim Tab (toward Keel) to the Right edge of Transducer is 8.75 inches.
[*] Left edge of Transducer (toward Keel) is 3/8 inch below the angle of the transom and is parallel to the water.
QUESTION:
To help eliminate breaks in the bottom detail, where can the transducer be placed since I only have 4.75 inches from the swing radius of the prop?
