2PRODUCT DESCRIPTION
2.1 OVERVIEW
The Kobelt 2048 push-pull control head features twin-engine control with both the clutch and throttle
control integrated into each lever. More specifically, this control head is intended to control two
transmissions with lever type shift valves and two engines with lever type throttle control. The control
head also features a spring-loaded throttle override which permits running the engine with the clutch
disengaged.
The 2048 is available in a combination of black and chrome, all black, or all polished chrome to suit your
appearance preference. Accessories, such as neutral safety switch kits or throttle extension kits can be
ordered with the units or as after market parts.

2.3 MODEL CODE KEY
The 2048 control head can be configured in several different ways. Below is a key defining the letter
code options:

3INSTALLATION
3.1 MECHANICAL
The control head must be mounted on a flat surface strong and stiff enough to withstand the cable
forces listed in the technical section without excessive flexing. Choose a location that has sufficient
room for the handles in both extreme positions.
The control head is equipped with (4) four clearance holes for #10 (M5) screws or bolts inserted from
underneath for direct mounting to the dash. Ensure the unit is securely fastened, preferable with an
anaerobic thread locker such as Loctite 243. Before securing the screws, ensure the detent roller
mechanism is in the forward position.
3.2 CONTROL CABLE
3.2.1 Hardware
The 2048 control head can be used with either 30 series or 40 series control cable. Kobelt
Manufacturing does not recommend solid core cables. A solid core cable would consist of a single wire
that is too stiff. Multi-stranded cores are more flexible and therefore generates less friction during
operation.
The cable ends must also be able to articulate
approximately 8 degrees in either direction.
For terminating the cables Kobelt
recommends a ball rod end. Rod
ends are self-aligning and cannot
and therefore minimize friction and
binding.
When installing hardware to the cable end, do not twist the core. If required, use a pair of pliers to hold
the cable core from turning while installing the terminating hardware. When gripping the cable end,
apply the pliers immediately under the threads and take care not to score the cable rod. A scored cable
rod will damage the cable seal allowing moisture and dirt to enter the casing.
3.2.2 Cable Routing
Measure the cable along the path it will take from where the cable hubs
will be anchored at each end. Follow the actual cable path as closely as
possible, allowing for the largest practical bend radii.

2048 Control Head Kobelt Manufacturing Co. Ltd.
Rev A mnl_2048.docx 9 of 21
Do not force the cable into tighter bends than what is
listed in the table at right:
It is important to securely anchor the cable hubs. Any free-play in the cable clamp or mounting bracket
will be perceived as lost motion or “sponginess” and will reduce the detent feel.
When securing the cable with clamps, it is recommended
practice to position two clamps at the ends of the bend
rather than one in the middle.
When installing a push-pull cable, do not kink the cable since
this will permanently damage the core and casing, rendering
the cable stiff and inoperable. Even minor kinks will result in
premature failure.
It should also be noted to avoid routing the cable near sources of heat, such as exhaust pipes or cold,
such as refrigerated fish holds.
3.2.3 Control Head Connection
The 2048 control head has a lever
mechanism for actuating the clutch and the
throttle that permits the cable to be installed
in either push or pull.
In some marine applications with twin
engines, both engines are turning in the
same direction and therefore one gear box is
running in the reverse to drive the propeller
ahead. In this particular installation the shift
cable must be connected on the opposite
side of the support bracket and cam to
provide the proper push and pull mode for
either gear.
The clutch valve mechanism on most marine
transmission requires approximately 2¾” (70
mm) to 3” (76 mm) of travel. Consequently,
the cable must be attached on the clutch
lever, item “A”, in the outermost hole of the
support bracket (pin position 4).

2048 Control Head Kobelt Manufacturing Co. Ltd.
Rev A mnl_2048.docx 10 of 21
To correctly install the clutch control cables, follow the steps below:
1. Secure the cables to the support bracket with the appropriate cable clamps.
2. As illustrated in the diagram below, move the control handles to the extreme forward position.
3. Ensure that the cable end extends slightly past the clutch lever attachment point (position A).
4. Move the control handles to the extreme aft position.
5. Ensure that the cable end, when in push mode, extends beyond the cable attachment point
(position B).
6. If the cable end points from one extreme to the other are unequal, then the cable end fitting must
be threaded out or in to correct.
7. Repeat steps 2 to 6
8. After the proper position is found, the cable end is attached to the clutch actuating pivot plate
and the jam nut tightened.
9. The final step is to test that the clutch control valve goes from neutral to both forward and then
reverse gear engaged positions without bottoming. A slight amount of end play is essential.
The throttle cable is installed in
the same manner. In order to
obtain full handle travel in the
speed range, it is important to
select the appropriate connection
point for the adaptor kit on the
throttle pivot plate.
3.2.4 Actuator End Connection
When connecting the actuating end of the cable to the throttle or
clutch lever, install the cable so that the greatest loads are in tension
(pulling) rather than compression (pushing), if possible.
Where the cable is connected to a lever, the cable must be
mounted so that it lies on a plane (A) midway on the arc (B)
described by the movement of the connection point on the
lever (C).

2048 Control Head Kobelt Manufacturing Co. Ltd.
Rev A mnl_2048.docx 11 of 21
When connecting the actuating end of the cable to a spool valve such as
the Kobelt 4605 servo cylinder, maximum cable life and efficiency is
achieved when the cable is aligned with the lever in two planes.
Reference the figure at right:
3.3 ELECTRICAL
The 2048 control head is available with an optional
neutral safety switches. The switch attaches to the
mounting holes, as illustrated as item “C” and is
operated by cam “D”.
The switch is prewired with a 1 foot [305 mm] long 18
AWG wire for external connection. Connect it to an
electrical junction box and the propulsion system
interface.
The product’s 3C/18 electrical cable contains the
following wires and related functions:

4COMMISSIONING
4.1 INSPECTION
Before putting the control head into operation, check the cable connections at each end to ensure that
there is side clearance between the sleeve and the core rod and no misalignment at either the clamp or
the control head which will make the cable stiff.
It is possible that a cable end may become bent either in transit or during installation. If this has
occurred the cable must be replaced as it will bind between the core rod and the sleeve.
4.2 FUNCTIONAL TEST
Do not put the vessel into service until the control
head has been tested. The Functional Test should be
carried out while the vessel is still at dock.
After installation, test that the clutch control valve
goes from neutral to both forward and then
reverse gear engaged positions without
bottoming. A slight amount of end play is
essential.
Also ensure that full speed range is obtained with
full handle travel.
Ensure that the throttle friction adjustment is
adequate to hold the throttle position. Adjust if
necessary.

5OPERATION
The Kobelt 2048 is equipped with a clutch bypass to permit operating
the throttle without engaging the transmission into gear. To operate
this feature, pull the handle outwards while in the neutral position
and then operate the lever to the desired throttle position.
The control head is also equipped with full throttle detents in the
forward position. This detent is engaged at the 92 degree position
(over center).
6MAINTENANCE
6.1 PREVENTATIVE MAINTENANCE
•Quarterly (4 times per year)
oEnsure that the throttle friction adjustment is adequate.
•Every 2 years
oInspect cable for wear
oLubricate pins & rollers
oInspect throttle & clutch bushings for wear
6.2 INSPECTION
When a cable core is pushed, it will take the longest route and, conversely, when pulled, it will take the
shortest route. This appears as ‘lost motion’ at the actuation end. The cable stroke must be measured
periodically to confirm adequate stroke.
