transducer mounting help

[Fishwhisperer619]

Hey guys, I have a rather uncommon kayak, a perception sport caster 12.5 and had just put on a humminbird piranhamax fishfinder on it with a suction cup transducer mount on the side that I pop on and off when I load and unload. Its been working pretty solid so far but I am looking to do a more permanent installation of the transducer but am unsure of my options/limits. I have a tendency to mount the suction cup at a slight angle, and the suction cup pops off from time to time. Should have some pictures to help out visually in the near future. But for now any suggestions? Thanks

Thanks for he help. Im leaning towards the hull mounted transducer with the goop but am curious what that does to the water temp reading, as well as the quality change of readings. Thanks

I have a cuda ff and when I went from in hull to wet mount I noticed a big improvement on the temp and the depth readings. However my depth readings are off about 3 feet. I have reset the ff numerious times but still the same 3 feet, must be a bad ducer but it works for me.

I figured as much. Ive heard people swaring by it and people who absolutely hated it. At a crossroads right now

Does your FF have a keel offset option?

not sure what that means. its a piranhamax 160 on a scotty mount. nothing out of the ordinary i dont think.

Since you've already used your transducer, the free exchange option from Humminbird is no longer an option. You can just buy their excellent flush-mount through hull xducer for about $35, though. That is what I used on my 'yak. Yes, you have to drill a two-inch hole in the hull. But with the rubber washers included and a bead of goop, it'll never leak.

I have the same fishfinder, and my setup is outstanding. Perfect readings of depth, structure, and fish. However, my replacement transducer doesn't have the temp sensor. I carry a simple digital thermometer that I drop into a scupper to make up for it.

Outside view, installed. Note that it protrudes from the hull only 0.20" and is flat.



Here's what it looks like from inside...

yes reset it to 0 still off. My pool is 8 feet I tape measured from the yak to the bottom and its 8 1/2 deep but ff reads 11 1/2 not a big deal except I had to set the shallow alarm to 7 feet to protect the mirage drive.

What I meant is to set it for -3 so that it reads correctly.
