I have a Raymarine st60 paddle wheel. It is sensitive to how i insert it paddle wheel unit into the tube and i believe that is because the tobe has a little shutter which is supposed to slow water entering the boat when i remove the paddle wheel. Just a little adjustment up or down and it can go from showing zeros to speed i expect. I calibrated the I50 display against gps speed on the chart plotter. Might help in your case
