Transducer position?

[acraw]

This get asked a lot, but before I drill any holes want to make sure.
Fitting a new system, if you look close in the picture you can see where the old fitting was, which I am sure was too close to the prop.
So not sure if to go right out to position 4 on the masking tape.
The instructions just says min 3 inches starboard of prop

[jeffstevens763@g]

Yep mine says 4 inch to starboard of the prop minimum also set level with the water not the hull and depends on the transducer how deep mine is a skimming transducer and in line with the hull. Having said all that I've seen them port side and work perfectly well

I'd suggest moving it about 6 inches..........
Towards the Bow.

Bed it down inside the hull where it's out the way, and won't get flipped up or damaged.
Lots of threads on here and other forums about how and why.

mines about where your old one was and works well up to about 25 knots on my last hull it was further away from the prop and closer to the water line but it must have come out of the water at about 10 knots as i would lose the signal

Hello, to find the right position for the installation of a probe the easiest is to take some photo while sailing to see where the water is not too disturbed! on trailer like that it's too random!

IF you can get to the solid part of the hull stick the transducer inside the boat with with silicon. No drilling ir cutting needed and works well at all speeds

Yes i have both my garmin (designed for transom mount ) tranducers araldited in the single skin floor of the boat on my ribcraft and nautica ,never fail even at speed ! ........if you need convincing before final position you can take the sensor out boating in your hand (wired into sounder) and use some KY jelly under the sensor to move it around to find the best position /signal

This is what I want to do but the bottom of the transducer is curved while the hull of the boat is relatively flat. Do you embed it in what becomes a solid block of silicon? How could the SideVu work? Pictures anyone please?

Hijack alert: Does your Garmin have downvu? Does that work shooting through the hull? Always installed my TD's in the hull as thru-hull TD's are so overpriced but not had one with the newer downvu/structure scan or whatever each company wants to call it.

HI hijack ,both my applications are older style £50 transom mount ,duel freq units ,one on a recent striker plus and one on an older 451s ,i cant answer the success on the latest side view stuff ,i have always found the garmin guys second to none on help line . maybe get the K-Y jelly out and do a few tests and report back ,would be interesting to know outcome as i need to upgrade soon .

I would but reluctant to spend out on one before I hear if it works.

Hello I am equipped with a Humminbird Solix not the same transducers but it is the same principle:
mounting glued tranducers is very practical, especially at high speed, there is no risk of tearing it off!
On the other hand, especially for 2D chirps probes, they must be in the water at the risk of destroying them by heating!
Another consideration to be taken into account in order to have a correct depth is to have the tranducer very horizontal in navigation, which is more difficult to achieve by gluing.
For the adjustment, we draw a line on a wide strip of sctocht on the console with a level during a test, this line will serve as a reference for the installation of the tranducer.
The SIDE and the like will not work correctly in glued assembly!
For the DI to be tested but there will be a loss just like in 2D but more important (reduction of the max depth)
There are through probes rather reserved for slow boats, on fast hulls there have been accidents due to the outgrowth under the hull, be careful!
On my, XSRIBS I mounted the transducers on the board after selecting the position by photo with plates permitting a fine adjustment of 2 cm of the height without having to make additional holes.
