Hey guys, I just recently purchased a new Humminbird unit with side imaging for my boat. Ive got the transducer mounted and everything well on the transom, I haven't tried it out yet, but as I was thinking about it, when the outboard is fully trimmed down wouldn't that interfere with the reading of the transducer for side scan? The transducer is mounted on the port side of the transom at the bottom. And when the motor is fully trimmed down, woudnt that obstruct the view of the left side? I am already planning to trim my motor up a bit when utilizing side scan just incase it would interfere. But just wondering if that actually would interfere with the reading, and yalls thoughts?
If it's on the port side, physical engine interference would hurt the right side view. When looking at the transducer, imagine a giant half-circle where the mid point of the half-circle's straight line is at the furthest point of the transducer that hangs behind your boat. If anything is inline with this half-circle, you will lose image quality. The way to fix this is to either lower your transducer or trim your motor up while scanning.
I keep mine higher on the boat because it protects the transducer from logs and does not interfere with engine performance by creating drag. Thus, when I come off plane, I trim up my engine. However, more and more folks are lowering them into the water flow just like a skimmer. I plan to lower my position when I get a new transducer. However, mine has been doing the job as-is for the last 6 years. But... My image dies at around 6 mph and I would like to get an image at faster speeds.
Thank you guys for the insight, drag, my transducer is set up very similar to yours. However I think with mine the outboard is cutting in front of that half circle that yam was talking about. So I might have to trim the motor up when using side scan, which I don’t mind, but thanks guys
