Simrad NSX v. Garmin 8412 (un-derailing 255 FSH Sport H have different impellers)

Further outboard, more holes. No Problem.
Forward of the starboard transducer is the STUPID OEM Simrad thru hull transducer. That is a hole I wish I didn't have. It is on my list of things to remove.

Its why Yamaha includes a plug for that hole if you choose to remove it. Many have asked that question when they found the plug included with their boat. They had no idea what it was.

I agree to close to the center line of the hull, another inch or 2 further out would help. Also the starboard transducer is inline with either the speedo pickup or livewell intake (I cant tell which) which was inducing turbulence for the transducer.

It’s inline with the factory through hull transducer
 
I am going to remove the OEM through hull transducer when I have time to patch and gelcoat the hole it will leave.
