Transducer Placement

[mugwump4]

So, I finally moved my transducer from the toilet bowl wax ring in the bilge to the transom. It picked up depth just fine through the hull, but I never got any of the resolution that was promised with it. Trolling slow, I do get great detail of the bottom now! But, as soon as get above 1/3 throttle it completely loses signal.

It's a 1977 23' CC with a full bracket.

If anyone is curious, I use a Raymarine Dragonfly7 with GPS. Awesome piece of kit!

Any suggestions on placement?

I HAD IT ON TRANSOM FOR YEARS. THRU-HULL IS THE ONLY WAY TO GO. PERFORMANCE WISE.

From the photos, it seems the bottom edge of the transducer is still slightly above the bottom of the hull. Once you get some speed up, there would be a fair amount of air/turbulence created thus distorting the information it's trying to send/receive. Put a straight-edge up against the bottom of the hull, in line with the transducer and parallel the keel. If there's daylight between the 'ducer and the straight edge, you need to lower it to match.

Hope this helps.

If you continue to loose bottom after lowering it, give it a little to angle to shoot forward (not a lot). Play with the angle at different speeds until your picture is consistent.

I've dropped it down another 2", to where it is prominently lower than the bottom of the hull. Still no love.

The bracket is garbage as well, and I've had to use a couple of star lock washers to hold it when tight. No matter what i do, I cannot get it to read above near-idle speeds. Unless someone has a suggestion, I'm going to have to move it back into the bilge and bed it in some silicone.

Happy Easter, all!

I mounted the ducer for my garmin 94SV under the bracket on my boat and right next to the drain plug to get the most out of side scan, and is $ accurate at all speeds

DDD241,

Can you share a photo? I owned bracketed 232. I run Simrad GO9, mounted by TotalScan transducer near drain as well. Great at slow speed, but, I loose sonar only at high speed. Like to see your positioning. Thanks

I can try, haven't ever had luck posting pic here, I should have said is not a mako, but is a very similar hull the same should apply

[ddd241]

once again, no luck

once again, no luck

All you have to do now is set the photo on your desktop or attach straight from you gallery using the camera icon in the upper left corner of the dialog box I have been using it and it works great much better than going thru photobucket or imgur

I tried about 10 times didn't work, I can attach a picture on any email or any other website then here for some reason
