My
boat has an old Kenyon
knot meter on it that tries to
work but doesn't. Once the
boat is moving, the meter reads 2 knots, and doesn't change until I get up to about 6.5 knots, at which point it often jumps up to read 10 knots. So something is going on between the meter and its transponder, but not much. Since the boat comes out of the
water every
winter, I took a look at the transponder. The paddle
wheel in it spins freely. It did have a little
bottom paint on it, which I scraped off, but I doubt that makes a difference. I did note, however, that the paddle
wheel is aligned at a sharp angle. It is mounted a bit fore of the fin
keel, and faces more toward the centerline of the boat than fore and aft (angle of about 60 degrees). Kenyon is long out of business, but it would be nice to have a read on STW as well as SOG. This presents three questions: 1) Is there a way to check whether the
knot meter itself is functioning correctly; 2) Is there a compatible paddlewheel transponder available; and 3) Is the alignment of the paddlewheel likely correct (it does seem unlikely that someone would have moved it). Thanks
