Hey everyone, my 2014 Horizon H190 came equipped with a Faria depth gauge that also can show water and air temperature.

I am trying to find out where the transducer(s) are located. I do not see any external cables or transducers on the hull anywhere.

An option the gauge provides is to set the depth offset, depending on where the transducer is located, to provide a more accurate depth reading. I'd like to set this offset to align the actual depth of the propeller/drive unit to water depth, since, I would assume this is the most important thing to watch for to prevent grounding of the propeller/drive unit in shallow water, such as at a shallow launch, etc.

If the transducer is inside of the hull, any idea how accurate the water temperature reading is, or how the water temperature is calculated?

If anyone has any tips on trying to find the location, or setting the offset, please help out.

Thanks!
Steve

It depends on whether your transducer is a through-hull, or internal. Start by looking underneath on the outside of the hull in the area under your engine compartment - you may see a black disc, which would likely be your transducer.

It's a small black disc, probably about 18 inches forward of the drain plug. Mine is just off the one side, maybe 8-10 inches from the center line. I never calibrated for depth last summer but I may this year. I found the temp to be pretty accurate, for both water and air.
Here is the model that we both have if you want more info:

Thanks all,

I'll take a closer look next time I have the boat out of the garage.

OK guys, next question, along the same topic lines...

According to the FW website the draft of my boat (drive up) is 16", draft (drive down) is 33"

So, if I understand this correctly, the propeller/keel/skeg/rudder should come aground in around 33" of water depth (dependent on load of course)???

According to my depth gauge, I have been in water less than 33" (I've seen 1.9' to 2.5' on the gauge) and have not hit bottom.

Curious, is this just because the depth gauge is not 100% accurate all the time, maybe depending on type of seabed, or some other seabed condition/material?

My main reasoning for these questions is I of course would like my depth gauge to be as accurate as possible, (so I'll likely change the offset once I figure out exactly what I need to change it to) and I would like to determine what water level is safe to keep the drive all the way down, and at what water level I should start thinking about trimming up to give my lower unit a little breathing room so to speak.

Thanks everyone for your input!!!

Very true "maybe depending on type of seabed, or some other seabed condition/material?"

Once both the stock depth gauge and my fishfinder both read "0". Alarms went off. I was in a bed of kelp and in at least 6' of water.

My 278 Vista has such a depth gauge. I have no idea where the water temperature sender is, but it seems to work (it agrees with the water temperature shown on the fishfinder and the VP EVC tacho). It is not mounted externally, so I guess it's mounted or maybe lying on the inside of the hull somewhere, below the waterline.

The air temperature sender has not been mounted anywhere; it's lying loose in the space behind the instrument panel, it's cable still coiled up. The sender end of it is potted in an off white plastic version of the clam shell covers they use for the anchor locker drains. According to the Faria manual, the water temperature sender looks similar.

This would be the difference between where the transducer is mounted and the surface of the water. So, if it's 16" below the waterline to the transducer, then add 16" to the displayed depth. Most gauges have the ability to enter this offset into it so that true water depth is displayed.
