Well I've heard of them, just never heard of the built in speedo pickup.
Mine's part of the depth finder transducer, has a little spinner wheel and
is electric. Thanks for the info. I haven't looked closely at the black
ones for several years. As for being an "obscure" make, well not right now,
but headed that way.

An obscure make called "Mercruiser"
Some model they call the "Alpha1 Gen 2" has an integral speedometer
pickup,
so does a model they call the "Bravo"
From my research they seem to comprise 75% or so of the outdrive market,
but
I have never heard of them.
