WX 1850 & HD SI Transducer

Trying to determine the best location on my WX1850 transom for my Humminbird SI transducer(XHS 9 HDSI 180 T). If anyone has pictures they would share on their placement, that would be great. I will be using the in hull transducer for 2D so I don’t need it for onplane readings.

Here is an 1850 we just rigged. It has the smaller compact SI ducer on it but would still be mounted in the same place as the HDSI ducer.

This is how I mounted mine on a MX1825. I didn’t need to drill any holes in the hull. Works great.

Did you purchse the bracket or did you make it? I like the idea of not drilling holes!

Thanks for the picture!

Shouldn’t the transducer run just below the step line. In this photo the transducer looks like it is 1/4″ above the step.

Thanks for posting the picture!

I make them.
It is mounted high enough to protect the transducer from impacts. It only works up to about 6 MPH. when the boat starts to plane the transducer comes up out of the water. This isn’t a problem because SI and DI are only really useful at lower speeds and I get 2-D info from a glasses in transducer using a AS SIDB Y cable that splits SI and 2d, to run both transducers to one unit.

If you want your HDSI transducer to work at on plane speeds it must be located with it’s face slightly below the lowest step of the hull.

Here is a picture of a HDSI mounted to read at on plane speeds.

Thank you! Good information. My project today is setting up my Helix 9 SI & 10SI. Fish don’t stand a chance now! lol
