Re: [OMC-Boats] Manual question

Bill,

I forgot about the "welch" plug ID located on the Port side on the top
of the vertical drive assembly of the sterndrive leg. Early models had
the sterndrive model number stamped on it. (HUE-12M for example would
be a 1964 150 hp Buick V6).
Later model sterndrives actually had a 6-digit part number and
horsepower rating visible. My 1971 has "210 HP" clearly stamped into
the welch plug.

If you are standing behind the point and can see the black rubber
bumper at the top of the drive unit, the welch plug should be visible,
just slightly to the portside of the bumper.
The round welch plug is visible when the rudder is either straight
ahead or in the forward starboard thrust position. If the rudder
(prop) is turned to the Port side then the rotating upper cover will
obscure the welch plug.

It would be interesting to see what other owners report finding on
their sterndrive welch plugs. I'll bet you aren't the only owner with
a potentially non-original unit.

Hope this helps to ID what you got.
