Shout out to KMoose

[take a potter]

Just wanted to give a Thank You to Ken. I wanted to make sure that I installed a new CHRIP/Clear Vu Sonar/Transducer, in the best possible way on my 23' CC. I reached out to Ken and he took the time to me more than helpful. I followed his instructions and I now have a sonar that works fantastic. I can hold a bottom signal in 500' of water at 30 mph. Thank you Ken.

Ignore the scum line, have not had a chance to wash it after the 15hr drive.

Here are a couple of pictures.

Impose, why put the transducer on the starboard? I have mine and basically the same spot on the other side but I just redid the transom and I am getting ready to remember the transducer. Previously I added Mount directly to the hull. It's an extremely similar transducer being the Simrad go series.

That last post should read Impose not Impose. And when I say starboard I'm referencing the material not the side.

My understanding is that the 3/4" setback that you gain from the starboard gets the transducer set back into cleaner water as it comes up off the transom. Additionally, though I over drilled and bedded the screws into the epoxy, some folks rough up or create tapered pockets in the starboard, and glue it on using 5200 for example. Either way you can move the transducer around to get the best performance and not put additional holes in the transom.

I understand the reason he used the starboard and it beats having to patch and redrill if the first try doesn’t work out.

Thanks guys, nice idea. Having just redone my transom I relish the idea of not putting another hole in it. Looking at it, it I see the bottom of the transducer is just above the trailing edge of the transom for clearance but is there a magic height?

Rybones, if you notice the starboard is actually 1/2" above the bottom of the hull. You do not want to extend the hull. You want the water to come off the bottom of the hull and start to rise as soon as possible. This makes it so that you can position the transducer just a little bit higher since the extra 3/4" of setback lets the water rise that much further before it hits the transducer. What I mean by a little bit, my experience was about 1/8" higher. With that said the transducer at it's lowest as it relates to the hull(in my case the right side) is still about 1/2 the thickness of the transducer below the hull. If I would have had more time I would have looked for a piece or 1" thick starboard instead of the 3/4" just to gain that little extra rise in water off the hull. But all in all I am very happy that it performs the way it does.

Roger that. Thanks

I just added a Garmin with the same transducer as take a potter did in this two year old post. Tried to duplicate what he did except used 1" starboard instead of 3/4". I understood he kept the bottom of the ducer a bit below the hull. At speed it seems to work well but gives quite a vertical rooster tail splashing up to the engine cowling. Didn't have that issue years ago with my Sitex, but probably didn't have the ducer creating a dam to water flow. Anybody else got this issue or should I simply raise it a bit? Raised it within the slots in the bracket and seems to have helped slightly. Just looking for advice before drilling more holes Thanks
