I have purchased the paddle wheel, anyone replaced one of these? Is it hard/easy? I sure hope it's this $30 part
and not the entire transducer (10x that amount)
Thanks in advance.

Very easy.
Put the boat on the trailer. Don't want to do this in the water.
Pull up your v-drive access so you can see the hull.
Look for the black AIRMAR triducer. It'll have wires coming off it. This will be on the port side slightly from the V of your hull.
Unscrew that transducer, should be able to do this by hand.
Pull the tri-ducer through the thru-hull connector. You'll pull the paddlewheel assembly with it.
Replace paddle wheel. Make sure the "scoops" face towards the bow of the boat when its reinstalled.
Screw everything back in place. Be sure the arrow points towards the bow so the paddle wheel is facing the correct direction.
Voila, you're done.
If things still don't work, there's another thread on here that has some info on how to test certain wires to be sure you're getting a signal from the triducer. That will determine whether or not its bad.
