Mine is from Raymarine and it is removable for cleaning while the boat
is in the water. I keep the dummy plug in the thruhull except when I
need to use the speed instrument. Takes a couple minutes to swap out,
but not a big deal. My old one was a 1986 Standard Horizon that was
still working when I replaced all of my instruments a couple years ago.
You can use a water based antifouling paint on it if you wish, but I
don't bother.

For ages I have had a Standard-Horizon SL1 speed log. The instrument
eventually died and was replaced. The impellor was always getting
gunked up and then died for good. The instrument died again. I got one
instrument and two impellors from Fleabay. One impellor died quickly
and the other one died just now LThey were all new in box too.
I am about ready to just look at the GPS and give up on this. Is there
a modern speed sensor that actually lasts? I remember replacing a ton
of them back in the day as an Autohelm dealer.
