Mighty Mariner

A Simplified Electronics System for Small and Medium Vessels

Why do boat owners insist on Kobelt Controls?
Kobelt is committed to manufacturing the finest marine controls in the world. Our reputation for superior marine controls is international spanning over 60 countries and backed by over 40 years of experience.

We are the only company to use die-cast bronze components and stainless steel hardware wherever possible, increasing the durability and lifespan of our products dramatically.

Kobelt offers the widest selection of electronic controls, available both in single and twin engine configurations, and governed by the strong principles of precision, reliability, and flexibility.

Always striving to improve and update out product line, we recognize the need for a simplified, reasonably-priced electronic control system for small and medium vessels; and the mighty mariners was born...

Navigate to the Mighty Mariner
Kobelt is proud to introduce its latest development in quality electronic control systems – The Mighty Mariner. This new mini system has all the same attention to detail and quality as its larger predecessor, yet offers a compact economical solution for small and medium craft.

The system is comprised of the 6505S control head in combination with the 6527-S electronic actuator, both in sturdy bronze and stainless steel.

The control head is completely watertight from topside* and can be used in any location on board. The 6527-S is a stand-alone actuator† with manual override. The electronics are stored in the housing of the actuator itself, eliminating the need for the separate microprocessor unit. The result is a pared-down, economical electronic control system perfectly suited to simplified needs.

The installation requirements for the Might Mariner are minimal. Communications is via a CAN Bus. This system offers up to 4 stations with station select, station lock, overriding throttle and synchronization**.

* the bottom is not watertight and must be protected from the environment.
† Can only be used for clutch and throttle functions.
**Synchronizer kit is extra.

Features

The Mighty Mariner works with various control heads, including the walk-about (Model 7176):

Troubleshooting

For more information see the installation PDF.

Symptom	Possible Causes	Remedy
The system is dead	The power is off The polarity is reversed on the DC power input	turn the power on Reverse the connections
There is a continuous sonalert beep	Control head CPU hangs up	Reset system
The system is not synchronizing	The synchronizer is not set properly There is a problem with the synchronizer wiring Parts are having different software revisions	Adjust the distance between the sensor and the target unit until the LED starts flashing Check the wiring Software versions need to be matched
All Actuators are moving erratically	There is a ground loop	Check and make sure the cable shields are isolated
1 Single Beep The control Head will become disable All control heads will become disable	The 6505-S Control Head, DIP switches are incorrectly set The 6527-S Actuator or the 6503 interface card DIP switches are incorrectly set	Check it DIP switches setting of the 6505-S control head, 6527-S actuator or the 6503 interface card
2 Consecutive Beeps	System temperature is above 60⁰C	Must provide venilation
3 Consecutive Beeps The Actuator will be disabled If the Clutch Actuator fails the throttle will default to Idle If the throttle Actuator fails the Clutch will default to Neutral	The Actuator is jammed The Actuator motor has failed	Check the push pull cable Check the wiring and the motor
4 or 7 Consecutive Beeps The control head will become disabled Control can be transferred to other stations if eqipped	One or more communication wires are missing One or more terminating resistors are missing	Check the wiring Install terminal resistors
5 Consecutive Beeps The Actuator will be disabled: If the throttle pot fails the Clutch will default to Neutral If the Clutch Pot fails the throttle will default to Idle	The Actuator Porentiometer is damaged One or more of the Pot wires are borken	Check the Potentiometer and replace if necessary
6 Consecutive Beeps The Control Head will become disabled Station lock will be disabled Control can be transfered to other stations if equipped	The control head Potentiometer is damaged One or more of the Control Head pot wired are broken	Check the Potentiometer and replace if necessary

Periodic System Maintenance

Inspect System wiring:
- Control heads wiring
- Actuators wiring
- 6503 Electronic interface
Inspect and monitor your primary and secondary power sources
Inspect your push/pull cable connections between actuators and controlled devices.
Perform a system functional test with the engines off and test system operation from all stations and for all functions available.

Operating Description

On Power Up:

System default power to station 1, station lock is enabled
Regardless of control head levers position, the throttle is preset to idle, and the clutch is preset to neutral, (mid position)
Sonalert intermittent beep awaiting for operator to acknowledge control.

Operating Mode:

Put levers in neutral position and press station select switch to acknowledge control
Sonalert is silent
System is ready to operate the throttle and the clutch according to lever command

Engine Warm Up
Press throttle override if engine warm up is desired. Throttle override allows you to control the throttle while the clutch is in neutral position. Levers must be in neutral to enable/disable throttle override.

Clutch Throttle Operation
Once in normal mode, advancing the control lever from neutral to full ahead will cause the clutch to move from neutral to ahead position and a proportional throttle signal from idle to full speed

Moving the lever from neutral to full astern will cause the clutch to move from neutral to astern position and a proportional throttle signal from idle to full speed.

Synchro Option
Press the synchro switch if engine synchronization is desired. The system will allow one lever to control both clutches and engines synchronized.

Both main and auxiliary control lever must be within 10% difference to allow engagement/disengagement of the synchro option.

Transferring Control to a Secondary Station
Disable station lock at the active station

Match the secondary station levers position to the active station levers position and press station select to transfer control

Operate clutch/throttle as per station 1 instructions.
