You might think about rigging up a way to put the 898 stock HDSI xducer on the TM along with the XTM 9 WIDE DI 20 T ...

You can use HB TS3 switch and simply flip a switch to choose the HDSI or the XTM 9 WIDE DI 20 T ...to have the best of both xducer technologies on the 898 at the bow...(using only 1 xducer at a time, of course)...

Above is how I have mine rigged at the front......

Well...sort of...

I also use the LSS 2 on my 1197 at the front also...

But that's another story ...
