Pro Tech Engine Timing

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I just rebuilt the 240 horse 351 in my boat and expect that the only possible problem may be the setting of the timing.

It is a 1992 SN with the pro tech ignition system. When I took it apart I adjusted the timing marks on the timing chain to the "installation position" and marked the distributor housing position to the intake manifold. I then marked the position of the trigger wheel on the distributor before removing it.

I believe that I can just reverse this procedure upon installation to get it started. However, I'm not sure about basic (or initial) timing although I believe it is 10 degrees BTDC.

Am I Correct? Will the Pro Tech ignition adjust itself? 

I can't seem to find the procedure or secifications.

	If someone could help me with this question, I would really appreciate it. Where to get information on the Pro Tech ignition system? What is the initial timinig supposed to be? If I get this one I'm pretty sure I can do the rest. Thanks to anyone who can help.

	Sorry to be a bother, but I went through a lot of the reference material and could find nothing about initial engine timing. There is not much that I can find. I think most of the manuels say take it to a dealer. Have any of you had any experience with the Pro Tech ignition?

	I don't have my Pro Tech engine manual in front of me so this information might not be 100% so use it cautiously but tyring to help you out on a holiday weekend. I think 8-10 degrees BTDC is about right but you have to turn off the engine first, remove the wire plugged into the knock sensor on the rear port side cylinder head, hook up the timing light, start the engine, and check/adjust the timing. After you turn the engine off be sure and plug back in the knock sensor wire. Hope that helps. Thanks!

	JR_Vic, You are unbelieveable. Thank you so much. That makes sense. I would imagine that as long as the knock sensor is disconnected, I could set the Initial timing close to 10 degrees BTDC and the Pro Tech would advance the timing until it sees detonation. It would then automatically retard it a couple of degrees. Maybe the Pro Tech will work fine Thanks again
