I have my SI transducer mounted about a foot away from my motor as low as it can go on the main part of the hull. Is there a better place to mount the ducer? I seem to lose SI a little over 3 mph. Feel free to PM or I can provide me email for pics.

Thank you,
Kyle

You will usually loose si unless you but the high speed transducer.

Sounds like you have a disruption in the water coming to the transducer, so that at 3+ mph, it is creating air bubbles under the transducer and cutting the signal. review the location and height.

Also consider a y-cable and high speed transducer to the system to make sure you maintain 2D sonar and depth at high-speed.

I appreciate you guys getting back to me. Do you guys or have you set one up on an 1890? the reason I ask is the transom is not flat down to the hull of the boat. There is a step in the transom so it is very different from other boats.

My bass boat has a huge step, the in hull in the bottom near the drain plug and then the si ducer is 10" hi on the transom and I wouldn't have it any other way sliding across sand, trees, weeds it's safe and protected

Also 3 mph shouldn't be an issue, I would reboot the sonar and set everything to default. Something sounds tweaked out of regular performance.
