The patient: '69 Coronado 25.
Ok guys, help me out here.
For the first time, I opened up the storage
locker under the quarter-berth. Inside, I found what looks like a red, thru-hull plug
with a funny
little egg-beater thing on the end, and a small cable poking out of the top. I had an odd feeling, and climbed up into the cockpit
and watched the knotmeter
dial while I spun the egg-beater. Yup, the knotmeter
needle moved. WHERE the heck is this thing supposed to plug
I have a sinking feeling about this: Under the galley
sink, there is a thru-hull for the sink/icebox drain. Right next to that, is a red cap plugging off another unused thru-hull that looks just like the red knotmeter cap except that it has no provision for a wire, and instead has a metal grab-ring. It's just a plug/cap.
Does the knotmeter egg-beater plug in where this red cap is under the sink? How the heck am I supposed to swap them out without flooding the boat?!
It seems that I have a perfectly working knot-meter and no way to deploy the flow sensor!
