Well, if a manual will help...try here:

To reset you should just have to remove power to the units.

The first thing I do to diagnose an Electronic Control Unit (ECU) is to make sure the fuel pumps are working. Power them up with a jumper wire (taking safety precautions). Check the pressure if you have the equipment to do so, but if they hum and purr and make gas flow their are probably O.K. Remove all jumpers and re-land all lifted leads. Next turn the ignition switch to ON and see if they hum and purr. If they don't you may still be all right. Next, with the ignition disconnected turn the ignition switch to start. If they don't work now you have a good idea it IS the ECU.

I have not encountered an ECU that did not energize the fuel pump when starting the engine. It is a good test for both of these components.

While writing this it occurred to me that it is unlikely that both pumps would fail, but not impossible. Plus; there may be a common pump for both engines

Correction to the above: When I wrote "with the ignition disconnected," I should have written; with the starter disconnected. That way you can hear if the fuel pump(s) is running.

thank you for ur assistance , actually i will double check today , especially regarding the pump .

A sinker! You've got to be kidding. Every single connection on the boat has to be renewed, (cleaned and lubricated). Including the ignition switch, which I would just replace, along with the alternators and any component that is not potted. You might be able to save the starters, but I would have them completely disassembled, rinsed in fresh water to remove the salt, rinsed in alcohol to remove the water, and then rinsed in diesel to protect them. Every disconnect plug is to be opened, sprayed with a good marine spray, and carefully inspected.

When a boat goes down, the batteries have a field day with the electrics. Everything is suddenly shorted, and corrosion to everything metal in the circuit goes wild.

Why do you think nobody wants a Katrina car?

of course all you mentioned is already done since the first day and the boat actually worked after that maintainance, what am assuming here is that the ECU registered a particular error and needs to be reset , and upon my knowledge of the automotive controllers usually resetting the error code of the ECU or ECM requires a diagnostic tool or a particular procedure in the system either by opening or closing some points in the electrical system in a sequence.

thanks for taking the time to reply.

i want to thank the ppl who gave me assistance in this , and am happy to say that the boat is working now , and yes was a matter of reset but with a particular procedure that i did without using a programming tool .

thanks again guys.

I have similar problem in my boat. I need to reset the code on my KAD44 but without using diagnostic tool. Could you please advise me on how to reset the codes?

Thank you for your support
