Transducer on a jet boat

[BRWNBR]

Where’s the best place to put a transom mount tranducer on my tunnel jet with pods? Any photos would be helpfull.

FWIW & YMMV.

I have gone through three transducers on my river boat. I finally gave up.

In my experience if you mount the transducer where it works well it will get broke.

If you place it where it it won't get broke it will not work well.

In my experience if you mount the transducer where it works correctly it will get broken.

If you place it where it it won't get broke it will not work well.

I wondered about that....

What about a thru Hull....

If you are wanting to try to read the depth while underway to keep out of too shallow water. You will be stuck before you see the water is too shallow.

If you want to read depth / bottom / fish when going slow over deeper water you can try what I did. Place the transducer on a bracket that you can flip up when running shallow and put down when wanting to read deeper water. I did that successfully, for a while, til I forgot to flip it up...

Unless there has been changes in the transducers since I had mine, thru hull does not work thru
aluminum.

I have a broken transducer and it shoots through(no hole in hull) the aluminum hull. Have had it since the boat(HCM) was new, no problems. I use it for depth only and it works very well at all speeds! I have posted in years past about how to do it, do a search and you might find some info.

Thru Hull is easy with a single layer of aluminum or fiberglass (no cores or wood in the mix). I have one on my duck boat. I made a box (4 sided dam) and bedded the puck in epoxy. They will work inside the hull if just sitting in water too (don’t need to be covered all the way even, but need some depth) Give it a try sitting in water in the hull to convince yourself.

i wouldn’t try it with a fancy transducer (like side image)

We've been using these with customers and they are working extremely well - even in heavier built boats. https://buy.garmin.com/en-US/US/p/530269

Yeah, I got tired of breaking transducers so I built a sliding bracket. I could slide it up and pin it out of danger or slide it down and pin it when I needed to use it. Worked great, but you do have to remember to slide it up out of the way when you're getting in close to shore....

When I hear through hull I take it to mean that the transducer "shoots" through the bottom of the boat, (not putting a hole in the bottom of the boat).

Personally I would not drill a hole through the bottom of my aluminum river boat for a transducer or anything else. It will be a weak spot and could be damaged and /or leak.

The unit macncoke linked to does shoot through the hull (no hole in the hull). But if A guy has the ability to do it/have it done properly (such that it's recessed in a socket just sub-flush with the bottom of the hull) the units which require a hole are really slick.

 

[hogfamily]

The bottom of my river boat spends too much time on gravel and rock bars to chance any hole that is filled with anything weaker that the original bottom. A recessed area on the bottom could be subjected to cavitation or other flow disturbance that may cause the transducer to not work well.

In my case Murphy would make sure that one rock slammed into that one spot...

You could try something like this with no hole in the boat.

I used a thick glop of clear silicone and glued it to the floor just in front of my intake. Works great, did it several years ago. I am using a Lowrance Hook4.

 

[Music Man]

If it is siliconed down and you dent the bottom and create bubbles in that spot you just move it to another area. Always test the position first before you silicone it down. I ran with the temporary 1/2 pvc coupler siliconed down with water in it with a small ziplock of sand to hold the puck down for a couple of months before I made that location permanent .

I used to have a Seaark with float pods. I had a transom mounted transducer mounted on the back of the right pod. It worked fine. I didn't run too shallow that often with it, but did get shallow/stuck a few times. Never had a problem with the transducer. It's really helpful to help keep you from getting too shallow. If you're running constantly in shallow water and expecting it to keep you from running out of water, it won't help with that. But if you're in bigger water, at least you can tell when you're getting to the couple of feet area.

You can also look for an "alumaducer" that is an "in hull" transducer. It will mount inside your hull, you won't have to drill a hole in your hull (thru hull).

Having ran my river boat with and without a depth finder, (yeah, it worked for a while), I would not spend the money on one.

Since I have stopped trying to get mine to work, about 10 (+) years ago, I have never once thought; "I wish I had a depth finder".

Take the broken transom mount and glue to the hull on the inside with epoxy....... done

We will call it a "in-hull".... a hole in the bottom of the boat is a "thru-hull"... listen to music man, he clued me years ago.... still working going 8-10 years now eh MM.....

 

[Music Man]

Yup! People still don't believe it is possible.
