Re: [OMC-Boats] OMC FACTORY SHIFTER DIAGNOSTICS

The 1962 - 1968 Evinrude or Johnson (non hydro-electric) shift boxes
are identical to the sterndrive units. Any of the Triumph-series three-
cyl outboard introduced in 1968 are hydro's and the outboard V-4's
beginning in 1969 are hydro's.

  The hydro-electric controls, I believe (came after my time) use
different electrical logic and therefore may not be direct subs.

The may be good source of common parts, however.

Just be careful when shopping, 3-wire, 5-wire or Hydro-electric will
all be different, depending on what's in you OMC boat.
