Haven't got the best results marking fish. Can see bait good but fish show as half a arch most of the time.. decided to checkout my transducer . Adjusted it even with the boat it was pointed with the tail end in the air.. also thinking it needs to be moved to the left a couple inches its right behind the crease on my boatAttachment 178189
Can you show more of your transom so we can see how far to the left you may be able to go ...??
I would think there would be much cleaner bubble free water just to the left of the speed sensor ...

Didn't know if you could put it behind that drop down
I need to remount a couple of transducers as well. I ordered a mounting board from Cabella's so I would not have so many holes in my boat. You might want to consider doing that before you move the transducer. I think it would read better if you moved it further left also, but make sure it will clear your trailer pad.
If you are wanting high speed depth readings ... Have you considered a "shoot thru" ... ??
Your hull looks like fiberglass ...

It is it's a ranger. Ist thing about the shoot thru is I ain't sure if I can get it adjusted right, once you place it its there, can't just loosen the nut and move it. Second is I wasn't sure how accurate the temp would be
I'm not an expert..............But If you are seeing bait good and you are seeing part arch's I think chart speed combined with boat speed dictate the arch detail.......
Does it read good when you are on plane? If yes than location may not be an issue.
What does your FF instructions say.......... does it call for ducers tail slightly up or down?
Never could get a good screen at all on plane but I always do marking at 5mph set on 5 on my humminbird
If you mount it shoot thru you will loose temp.
You could do a temporary shoot thru by using a piece of a wax ring for a toilet........... just to test out and see if it's in a good spot and works good.
Could use plumbers putty for the test as well, temp may work but will be off a few degrees due to the hull will eventually get close to the water temp. Have you considered mounting up under the step on the transom, lots of people mount it there.
An optional temp sensor and the AS T Y cable will allow transom mounted temp readings with a shoot thru mounted in the bilge ...

Which unit are you using presently ...??
If the unit has GPS ... Then the present speed sensor is not necessary ... And the xducer can be moved to where the speed sensor presently is ...

Or you could just opt for the XP-9-20-T inside-the-hull transducer that has the temp sensor on a 10 foot cable for mounting on the outside of the transom. I would test with the transom mount transducer first though. No need for plumber’s putty or anything on many boats to do this. Just fill a sandwich bag with some dry dirt, sand or pea gravel and place it on top of the transducer to keep it from moving around. Add a few gallons of water to your hull (enough to come half-way up the side of the transducer and test away. You may need to disconnect the auto-bilge pump for this test, so be sure to reconnect it afterwards.
When using on the inside do you set it dead center in the valley or up on the side of the valley. Sounds like a dumb question but want to be sure
Here's how to test the shoot thru for proper placement ...
