I have a 2018 25Sx tritoon and I'm installing a Garmin 943XSV plotter with a transducer. My question, where is the correct location to mount the transducer.
 
Do you have a bracket welded to the rear of portside tube?
 
Yeah…as low as you can get it on the port side pontoon bracket that should already be there.
 
Many do not have the brkt on the starboard side. I wish that was a standard thing. It certainly makes a graph install easier if one has underdeck wave shield.
 
so, question...

mine is on the bracket as shown, and parallel with the tube. That said, generally with the weight of the motor and folks on board, the tubes sit at an angle in the water... maybe 10 degrees or so. should the transducer actually be tilted to account for that such that it's more parallel to the bottom? how much difference does it make if so? (not sure i wanna go taking tools in the water to adjust. I don't have a way to get things out of the water till the end of the season, lol)

lastly, we got a stryker 4 setup with the boat... anyone upgraded to a better unit with side scan, etc? can i just replace the "head" unit? I think the transducer can support a better head unit with maps and sidescan, but don't know for sure...
 
Thanks - Echomap Ultra 106sv on a Balzout mount. The mount has indents instead of a rubber ball/socket so while it does not have infinity movement it will never ever shift while bouncing around. Billet aluminum that you could hang a truck off of.

GT54 transducer came with the MFD, great package.

It does make a differnce and will help.

IF…if you combine that with lowering the transducer slightly lower than the bottom of the pontoon, that will help the most. But angle certinaly does improve reading at speed. You eliminate cutting out due to poor angle, and then are left with it just cutting out if in turbulant water (which lowering below the tube often eliminates, but then also puts the transducer at risk, so…).

i'm all about risk... lol

220, 221... whatever it takes... ;)

Gotta love a Mr Mom reference!

Call it a hunch but the higher-end transducers like the GT54 don't seem to have as many problems finding bottom as the cheaper ones. Could be the Chirp frequencies it's sending out or wattage but I can read depth 30+ mph and my record was around 38-39mph before losing contact.

It's also quite substantial and quite long so air pockets and turbulence may be smoothed out as the water curls around the transducer allowing it to read better. Who knows - what I do know is it works great, all for the low, low price of thousands of dollars... definitely hide the bank statement that month from the wife.
