OMC Stern Drive, 400/800, Cobra, King Cobra, JV/SX
I get a
lot of requests for these parts, and have many available, however, there is
great misunderstanding identifying these drives, and this leads to some wasted
time shipping wrong parts. Before ordering, please confirm your drive.
The
original OMC stern drive was an odd unit produced by Johnson in the 30’s called
the Johnson Tilting SternDrive. To my knowledge, it was only used on a couple
of boats made by GarWood, and then forgotten. (Old boat purests will correct me
on the boat manufacturer if it wasn’t GarWood) In 1964 OMC began to offer the stringer drives.
(So-called because the forward thrust of the engine was transferred through the
stringers of the boat, and not the transom) This original design had an
electric shifting lower unit. The electric shift unit is easily distingushed
from the later mechanical styles because the propeller uses a shear pin, and
the exhaust exits above the prop and not through it. The electric shift
Stringers were available in two lengths, short profile, and long profile. In
order to get the proper upper unit parts, we need to know if your unit is long
or short. You can measure from the top of the drive to the cavitation plate
(the horizontal plane just above the prop) A long will measure 22” and a short
will measure 18”. The electric
shift lower continued to 1977. It is a pretty tough unit, and due to availability, and lower cost, many
shops are using these as a replacement for failed mechanical shift units when
the cost of repairing or replacing the mechanical unit exceeds the value of the
boat. If you would like to explore this option, contact me and we will put
together the parts you will need.
Beginning
in 1978 OMC renamed the drives with the designator 400 series ar 800 series.
Contrary to information you might find elsewhere, the is no “600” series. All 4
cylinder engines have a 400 drive, and all 6 cylinder and 8 cylinder engines
use an 800 drive. The upper unit drive ratio was changed to accommodate
different size engines. The first versions of the 400/800’s used a hydraulic
assisted shift mechanism similar to the v4 and v6 outboards these geacases were
based on. I would love to know why these were built with so many overly
complicated systems, but suffice to say, by 1979 all of the outboards had
abandoned this system, and the sterndrives followed closely behind, reverting
to an all mechanical shifter by 1982. While I do have some of the internal
parts for these “hydro-shift” units, we no longer support them in rebuilt units
we just upgrade to mechanical shifting. Minor modifcation of the shift housing
is required. If you are repairing a lower unit and need parts, I will need to
know if you have a “hydro” or not. The easist way to tell is to look at the
shift rack under the shift cable housing. A “hydro” will have the rack attached
to a round cylinder, the assist servo. The mechanical rack is simply pinned to a
threaded steel rod. While not considered a 400/800 after 1982, this is still a
good way to denote the drive size, just be sure to note “hydro” or mechanical.
1986 brings us to a wholesale change in OMC sterndrives; enter the Cobra.
Because of complaints, loss of sales, or just the change of patent status(WHO
KNOWS?) OMC redeveloped their stern drive, and it emulated the highly popular
Mercruiser unit in many ways. They both were transom mounted (using the same
engine yoke and socket, ujoints and gimbal bearing!) Used the same size
cut-out, allowing boat builders greater flexability choosing drives, and both
used hydraulic cylinders to tilt and trim the drive (The former OMCs using an
odd combination of a mechanical gear quadrant to lift the drive, and on models
so equipped, provisions to lift the entire engine assembly to trim the drive).
The Cobras were a welcome upgrade, and quite a good drive, with one very
glaring problem. The lower unit for the Cobra is very closely based on outboard
lower units, using the same casting (with the addition of some required
hardware, and stainless steel thread inserts) This retained the upper vent screw on the lower case.
Traditionally, this screw was used as the oil level indicator on outboards, but
Cobra units shared oil between the upper and lower, and a dipstick was used to
indicate the oil level in the drive (lower AND upper). Well, many a well
meaning owner, set on maintaining their drive, drained the drive, and filled it
up just like every outboard he had ever owned, to the vent/level plug! This, of
course, left the upper gear unit “high and dry”, and bearing failure was soon
to follow, as was an expensive repair bill, and a bitter taste for OMC, even
though it was a very good drive, otherwise. These Cobras (’86 to ’93) are still
quite popular and we carry a full line of drive parts, and many engine parts.
By ’94 OMC and Volvo went in to a joint venture (The “JV” in drive designators)
and produced a very good drive using the excellent cone clutch shifting and
durability of the Volvo drives combined with the good engines, and excellent
trim and gimbal system of the OMC’s. Volvo still sells this drive as the
popular SX stern drive. The Cobra name was dropped in the late 90’s, and OMC
was out of business by 2001. Also of note, but getting very rare, was the
KingCobra drives normally mated to big-block, or high performance small block
engines. These are separated in to two types, the early “clutch-dog style”
using a reworked v8 outboard based lower unit, and the “cone-clutch” style that
used a Volvo style cone clutch. The two types are easily distingushed as the
cover on the older “clutch dog” units is flat, and the later “cone-clutch”
units have a distinct bubble to the top cover.
So
this history should better help you determine which drive you have, and we are
happy to help. We have many parts in stock for these motors. In some cases, due
to interchangability, and updating through the years, we may need you old part,
or ask for an e-mailed picture to confirm fitment.
