Two problems - Fish tail caused by Transducer and Bogging down

[RWilson2526]

if your humminbird transducer is like the one I just added a little while ago make sure you installled the rubber plug that comes with it that fills the space between the transducer and the transom in between the mounting bracket. I forgot to put it in and got huge rooster tail.

edit: just did a little research and found that maybe not all the humminbird transducers were shipped with the rubber plug (comes with "high speed" transducers apparently) A work around is wrap some electrical tape around the opening.
