I have ST-60 speed that over time lost its reading. The paddle spun freely but no reading. I replaced the paddle and its function returned. I suspect that years of fresh coatings of anti fouling bottom paint on the paddle wheel built up a thickness that blocked the impulse. Pull the paddle wheel and try scraping off the paint.
