2006 36' Open    SONAR TRANDUCER ISSUE  
Tiara original installation:   E 120 Raymarine  with a Airmar M260 transducer 
New installation Garmin 1243 XSV with Airmar B75M Chirp transducer

Installed the new transducer inches away from old one close to the center of keel just aft of fuel tank.

The sonar is getting interference and loses the bottom when I accelerate and travel above 10 MPH. 
Connected the old M260, which worked well with the E 120,  to the new Garmin and had same issues.

It appears to me that the location of transducer is the problem,  has anyone experience same and found a solution?
Thanks appreciate any feed back.

Did you have the same issue with the Raymarine?

I suspect your getting interference from prop wash.

My transducer on my 3600 is located between the motors, offset from center to the port side.

 I did not have issues with the RAYMARINE gps
I have my fresh water tank that runs between engine so I really don’t have access to drill a transducer

It could be to close to the other one. Is it a little behind it?

It is close
Diagonally across from original transducer on the opposite side of keel.
Thanks appreciate your help
