Re: Plug in the upper part of the vertical drive on a 1977 OMC 175hp
The Stringer is a pretty good drive (on the overall). I actually really like the electric shift versions like you and I have - there is some real slick benefits to the shift style, and I still get compliments on how quiet my boat runs.
That said - stay on top of it. The Stringer can be a bit finicky, and likes a lot of attention (they apparently get lonely). Otherwise, it can be a very nice drive that will survive a lot longer than you'd guess.
Enjoy.
