94 electronic ignition

[getrdun]

Have 351 windsor out of boat for rebuild. How do we reset the unique electronic distributor to reestablish the correct firing order?

Somebody here may know, but I bet if you went over to www.correctcraftfan.com
- you'd get a detailed answer....

Thanks, I’ll give them a try.

Should be able to watch the procedure on YouTube. I don't think I could do that much typing. Maybe somebody close to you?

[getrdun]

Thanks, I’ll give that a try.

Is it the ProTech system? Do the plug wires run to the rear of the motor into 4 black boxes? Or do the wires run to the front of the engine to a more traditional distributor?

Pro tech system.

When you ask: "reestablish the correct firing order" what are you trying to accomplish? Was the "trigger" removed from the block? Or, are you simply trying to set the ignition timing on the ProTec system? The ProTec "trigger" is that hockey puck-looking thing at the front of the engine.

When the ProTec system in my 1994 Ski Nautique died, I replaced it with a marine HEI distributor. I was very pleased with the results. I opted for the D.U.I. at https://performancedistributors.com/...-distributors/

That's great intel on the marine HEI distributor!! Our ProTec is still working though but it had to be removed, for the motor rebuild. Wondering correct procedure to reinstall when motor is returned?
Thanks

[getrdun]

In case we do go with your suggestion, which Ford marine distributor option did you choose? ie. 7000 or 10000 rpm and with or without reverse gear?

Thanks again for all the help.

[Jonny Quest]

7,000 rpm version. Standard rotation. I doubt you have a reverse rotation engine as most PCM engines of that vintage were standard rotation with the PCM 1.23:1 transmission.

As you just rebuilt the engine, put a nice new distributor on it. The ProTec system is old and parts are no longer available. You will be very happy with the DUI unit.

Ok that seems like the way to go. Great info, thanks!! Will the DUI unit come with instructions on how to install/time properly with the 351?

Just sent you a PM (private message)

[getrdun]

Just got the private message. That’s amazing, really appreciate the help. So let me get the motor back and order the DUI unit. Looks like about 3 week delivery period but that’s ok because the motor will take that long. I’ll follow up when everything has arrived.

Do you have a carb or the throttle-body injected version (both were available in 94)? I'd agree with ditching the pro-tech, but if you have TBI, you'd also need to replace the TBI unit with a carb, as the protech managed the injection.
