If you haven’t pulled one before, you may be startled by how fast water rushes
in. Remain calm, and have your blank handy.

Dan, there are a lot of us who regularly pull our speed transducers. You may
get a pint of water inside (mine is under the dinette and drains into the
bilge). Fear not. Get someone to spin the wheel and see if it works.

Subject: Re: Stus-List padwheel issues
I had a tech support ticket open with Actisense (the Digital NMEA product I'm
using to read my data streams from my transducers) and they confirmed that if
the padwheel is not spinning, NO data will be formed and no NMEA sentenses will
be transmitted. SO - YES, the padwheel HAS to spin, and it's not a wiring issue
(95% certain)...
That said, I went out on deck and tried pulling a line along the underside of
the hull to activate the wheel and tried using oars to move the water around
the waterline but then it started to rain so I gave up the attempt. The only
other non-evasive method is to get in the dinghy and try to reach the wheel
with my hand... or bite the bullet and try pulling the sensor out completely
and replacing it with the plug which to me sounds like extremely risky business
but you guys seem to think it's a breeze...
WISH ME LUCK!

I never leave Touché’s paddle wheel in. Only put it in when we go sailing.

You should have a plug which allows you to remove the transducer with the
boat in the water. Simple process of pulling the transducer and inserting the
plug. If done quickly, you might let 2 cups of water in. Will need a person
spinning the paddle and one looking at the instrument.

Thanks guys.
Difficult to get the padwheel moving when the boat is in the slip and
there's no current lol.
I can try sticking my outboard motor in front of the boat and gunning it
to get the water flowing... or I can get in the dinghy and try to reach under
to spin the wheel manually...
Before I do that - I have a digital readout of my NMEA 0183 sentences so
I can analyze the readouts line by line. I don't even have a readout for
"0.0.0" on the speed (or any speed data at all) I'm wonderring IF the padweel
isn't turning, it will literally give back NO data / sentences at all? not even
a "0.0.0"?

I also had a paddlewheel issue caused by bottom paint. I did not
discover the nature of the problem was until the boat was out of the water.

The paddle wheel needs to spin to get a reading. I have an Airmar
transducer for the ST 60. It stopped giving speed readings even though the
paddle was clean and rotated easily. A new paddle solved the issue. My guess is
that the build up of bottom paint was blocking the impulse signal the paddle
creates. Perhaps scrapping the paddle free of paint might solve your problem.

Hi all, I have a ST850 Airmar speed/temperature transducer that I'm
trying to get working (again) with my new equipment. I'm pretty sure the issue
is with the wiring so if any of you have this transducer maybe you know where
I'm going wrong?
***My ST850 is from 2006 so I'm pretty sure it's not the "smart
sensor" one that is supposed to output NMEA2000 sentences directly.
With my old system ONLY the green wire was hooked up to a B&G nav
computer and the black and shield were connected to ground. (no temperature
data)
I've got:
GREEN to Speed Pulse IN (not sure what "pulse" is ecactly)
Black, and Shield to Ground IN
Red to Speed Voltage IN
Yellow/Red Stripe to Temp IN
Brown to nothing
With this configuration I'm getting Temperature NMEA sentences, but
no Speed. Anyone know where I'm going wrong? Does the padwheel have to be
turning to get speed sentences?
