2PRODUCT DESCRIPTION
2.1 OVERVIEW
The Kobelt 6506 side mounted
control Lever provides 5 kohm
potentiometer output that is
proportional to the lever position.
This output is used by Kobelt’s
Mighty Mariner or 6525 controller to
control engine throttle, clutch
engagement or propellor pitch. The
handle has three detent positions;
one at neutral plus another two to
correspond with clutch activation
points in both ahead and astern. The
detents and handle friction are user
adjustable.
The 6506 is supplied with a gasket for
either indoor or outdoor installations
and the handle is splined to permit
user selectable handle orientation.

2.3 MODEL CONFIGURATION KEY
3INSTALLATION
3.1 RECEIPT
Kobelt offers the 6506 control lever in several
configurations (reference section 2.3). Upon receipt of
the device ensure that the model number and serial
number are noted on the table in page 2 of this manual.
The serial number can be found in the location noted at
right. This model number will determine what spare
parts are applicable.
3.2 MECHANICAL
The 6506 Control Lever should be mounted:
•In a central location at each station on-board
the vessel
•With sufficient room for the handle to swing
fully to both extreme conditions
•Within 3 feet [0.9 m] of the remote selector panel
•With the external electrical cables protected from potential damage

Rev A MNL-6506.docx 8 of 18
The lever must be mounted on a flat surface with a maximum roughness of ra = 125 micro-
inches [500 m]. The mounting surface must have the following minimum thickness to
prevent excessive flexing:
Steel consoles: 0.19 inches [4.8 mm]
Aluminum consoles: 0.27 inches [6.8 mm]
The Lever is equipped with (4) four mounting holes for #10 [M5]. Use #10 or M5 sealing
screws or bonded sealing washers to prevent water ingress below the dash. Tighten the
fasteners to 23 in-lbs [4 Nm] with an anaerobic thread locker such as Loctite 243.
3.3 ELECTRICAL
The Control Lever has 4 foot [1.0 m] long 3C/18 cables for external connections. Connect
them to a 6505-2000 or 6505-3000 remote panel as required.
The product’s 3C/18 electrical cables contains the following wires and related functions:

The operating direction of the Control Lever handle is CW rotation for ahead throttle
command.
4COMMISSIONING
4.1 ELECTRICAL CHECK
Ensure that the rear cover is installed and secured before powering
up the 6506.
Confirm that the electrical connections to the 6506 have been made correctly and correspond
to the requirements of your system installation.
4.2 FUNCTIONAL TEST
The Functional Test should be carried out while the vessel is still at
dock and before it is taken out to sea after installation has been
completed.
A complete functional test should be performed on the system that the Control Lever has
been installed within before entering operational use.
5OPERATION
The Kobelt 6506 Control Lever contains one or two potentiometers. Operating the Control
Lever causes the vessel to engage in the ahead direction when rotated CW. When the lever is
released it stays at the set position and does not spring back to centre.
The operation of the lever can be reversed by swapping the black and white wires at the
remote panel.
6MAINTENANCE
6.1 PREVENTATIVE MAINTENANCE
•Quarterly (4 times per year)
oLubricate the detent track (reference section 6.3)

6506 Control Lever Kobelt Manufacturing Co. Ltd.
Rev A MNL-6506.docx 10 of 18
oEnsure that the friction drag is adequate.
•Every 2 years
oInspect detent plate. Replace if necessary.
oReplace shaft seal
6.2 CALIBRATION
When replacing the potentiometer
or if the setting has become
disturbed, follow these steps to
center the output:
1. Position the handle in
the center (neutral)
position.
2. Remove the control head
back cover.
3. Locate the
potentiometer in need of
centering.
4. Connect a multimeter to
the Pot –(white wire)
and the Pot Wiper (green
wire). Set the meter to
read resistance.
5. Loosen the two locking
set screws on the pinion
gear with a 1/16-inch
Allen key.
6. Using a short flat head
screwdriver, rotate the
potentiometer shaft until the meter reads half of the rated output (2500 ohms for
a 5K potentiometer).
a. Note: compare the output between the wiper and Vref+ to wiper and
Vref-. Adjust the shaft to balance.
7. Tighten the two locking set screws and replace the cover.
6.3 LUBRICATION
The track the detent runs along on the detent plate must be lubricated to prevent premature
wear. Use a grease with MoS2 additives for best results. The following greases are approved:
