The paddle wheel spins freely and the knotmeter works. The only thing I can 
think of is some random piece of goo was stuck on it from the dirty bottom and 
I never saw it because of the pressure wash at haulout.
In other news I got my spare impeller out and it works too – but it is missing 
the O-rings. WTF??? Good thing I looked now!

The paddle wheel should turn easily when you blow on it. If it doesn't then you 
may need to clean the socket in which it turns. Bleach helps.

I get growth in the slot where the little wheel spins. Have done a lot of 
'fixes' to make it work, and it is still spotty. I even bought a new wheel... 
no help. (Nexus)

Joe,
I had the same symptoms with my knotmeter last week. The boat had been unused 
for several weeks with the bung installed. I installed the transducer(s) before 
leaving the dock and the knotmeter read zero until we had covered about 5 miles 
when it started reading correctly. I assumed there was a build-up of growth in 
front of the paddlewheel, and it performed fine for the rest of the trip.

Coquina just got hauled this morning. Now I can go over and see why my 
knotmeter reads 0 underway, but if I pull the impellor out and spin it the 
readings are good. Any ideas why the paddlewheel spins freely in my hand but 
not in the water???
BTW – the diver that cleaned my bottom said now I had 3 different colors of 
paint showing maybe it was time for more LOL. The last time I painted I did one 
blue layer and one red layer over black original. It seems to have ablated 
itself right off the boat.
