I can let you borrow my spare XHS 9 HDSI 180T xducer..(we might be able to set up a place and time to meet)..

You will not be able to use the 800kHz frequency...but the 455 will tell you if the problem is in the xducer or the head unit...

Good point. You do not have to test it on another boat that has a 798 unit as the Si sonar will work on any of the Humminbird SI transducers that we have made. All you are looking for is some clear Si images in both the left and right Si sonar, so you can test it on a boat that has a: 981c Si, 987c Si, 797c Si, 898c Si, 997c Si, 998c Si, 1197c Si or 1198c Si unit.
