Midship Transducer Degree Angle

[Midastouch73]

Im planning a bottom paint haul out soon and I'm looking to install a new transducer while she's out of the water. Any suggestions on what angle transducer to use for a midship install wither between the engines or midship starboard leaning side? Looking at going with the Airmar chirp ready 175Hw 1KW transducer.
