Re: One Of The Worst Fouled Bottoms I've Ever Come Across
I find I can get away with leaving the speed wheel in, until about mid July. Then the growth is too much, if it sits for more than a few days. I hate to remove and replace, as it lets several cups of seawater enter the bilge, which I then clean out.
Even when I've neglected it and the speed stops reading, I've never found the wheel won't turn. I'm not certain how they work, but I think they are magnetic, not mechanical and the sensor notices the cups go by. The critters or slight fouling seems to interfere with the sensor, more than interfere with the cups spinning. If I don't have time for it to dry out and fall off, I find myself digging in there with a toothpick.
