Default Wiring and timing 8367 for Mercruiser 4.3?

I've got a stock 1993 Chevy 4.3 marine engine (Mercury Mercruiser) with a worn out stock Thunderbolt ignition. The engine is _not_ a vortec variant, has the old-style heads and is runs a stock 2 bbl Rochester carb - it makes around 190 hp.

I think the MSD replacement is p/n 8367. My question is will this install (ignoring the 4 pin input) require splicing. So, with respect to wiring this distributor up with the existing coil, what's involved?

Second, as this is a marine application, how should I set up the timing?

Can this be accomplished without an additional MSD control box?

Thanks.

If you can provide us with a Fax number I can FAX a diagram showing you how to set that up using that distributor without the connections for the fuel injection.

Unfortunately, there is no timing adjustment on that distributor if you are not using the fuel injection. You will have to run the boat at full locked out timing at all times. Start the boat, run the engine up to about 3,000 rpm and lock the timing down at the desired amount.

One more thing. Would p/n 8597 be a better distributor for this purpose? i.e., I guess both either need to be locked out or use the MSD ignition box, correct?

Another question: Can the 8367 chevy v6 distributor be used with the 6M ignition box? Which coil is best for this marine application?
Many thanks, I realize this is a lot of questions, but am trying to figure out the best solution.

We offer a number of different timing controls. The best to control the advance with the 8867 distributor, would be the PN8981 Programmable Timing Computer. This will provide an advance curve begining at 1,000 and ramp the timin up 20 degrees and stopping at 3,000 rpm.

The 8597 distributor might be a better distributor if not running the fuel injection in that there would be a mechanical advance. You would have to use at least a 6 series ignition with that application.

Basically, all the timing controls will wire between the distributor and the ignition. There would be two different ways to trigger the timing controls based on what distributor you are using (points/points amplified or Mag Pickup).

Some diagrams should be on there way shortly, if you need more or different disgrams, let me know.

idixon14,

Yes that would be a better choice. This way you will have the timing curves in the distributor. The one thing with this unit is it not marine certified. This has a magnetic pick up in it that would plug into one of the ignition boxes like the 6460 marine unit. We do not have a ready to run 6 cylinder distributor at this time.

Thanks,

OK,

Thanks for the comments. I appreciate all of them, and despite the marine certification issues, I think my best bet is to:

run the 8597 distributor
plug that into the 6460 marine unit
use the MSD blaster 2 coil 8203

with an "open-hatch" arrangement in this boat.

Please confirm for me that the 8203 is compatible with the 6460 box.

Thanks again.

That coil PN 8203 WOULD be a good match.
