Ignition Coil For Mallory Electronic Conversion

   Good idea with the white paint.  I got it to flash, just couldn't really see the timing marks.  Also, I got the boat in this weekend and it seems to help during start up to not give any throttle, and then give it throttle when it starts to fire.  I think I may have been flooding it with too much throttle earlier.

	Make sure you are on plug #1. Might help to take some white paint & mark the correct timing line, so you can see it easier in daylight. When you said you had no luck, did the timing light flash at all?

	Thanks for the information guys. The timing was set by the PO, however he told me that he set it by ear. When I bought the boat I picked up a timing light, but I had no luck trying to check the timing, I couldn't see anything. Any tips on checking the timing? I'm putting the boat in this weekend so I'll check to see if the coil is hot to the touch at shutdown.

	Is the coil hot to the touch at shutdown? I have a Mallory E-Spark and a Accel chrome coil. Still running the ballist resistor. The coil is in the stock bracket, horizontally mounted I bent the bracket as much as I could so the coil is on a little angle. Also have Taylor wires, works well (so far)

	Verify timing first. Cheap, quick, what the heck. Plus that's been my previous issues on hot starts with a 4.3 I had.

	Mike, I too have the Edelbrock carb on our 92, and was having the same issues. All indicators pointed to the Carb. However a thread here suggested coil replacement, the "Blaster", epoxy insulated instead of oil? (Cheap, maybe $30?)Did the trick! I even bought a Holley, and it is still sitting on the shelf, she is running so well. Good Luck.

	Thanks for the quick replies. If the carb is dripping fuel after shut down, is that due to internal seals in the carb leaking? Would a carb rebuild most likely fix that? The engine does have an Edelbrock marine carburetor instead of the stock Holley, by the way.

	No hesitation or issues when running it continuously. The problem only exists after I shut the boat off after running it continuously and try to restart around 10 minutes later and even up to until it has cooled down completely.

	If the only issue is hot starting then I would not suspect the coil. If performance degrades after the engine gets hot and the engine is hard to start if shut off, then maybe that would be something to look into. The first thing to do is look down the throat of your carb and see if its dripping after shut down- thats probably the most common (and easily diagnosed) cause of a hot start issue.

	If you were to run it continuously for some time, without shutting it down? Would it give you any trouble? Hesitation etc.?

	Hi all, I recently bought a '77 Nautique with the original 351 Escort XL motor with 750 hours. It has been converted from the original point type distributor to the Mallory electronic distributor. Per the PO, the conversion wiring has been installed as shown in the Mallory diagram. I am having the hot start issue where it takes forever to restart the boat after running it at temp. Cold starts with this boat are not a problem whatsoever. After doing some research on the forum, many contributed this same problem with an overheated, oil filled, and horizontally mounted ignition coil, however I have not checked for spark while experiencing this issue. The coil that is currently installed on the motor is labelled "NAPA 905" and is horizontally mounted. I'm guessing this is an oil filled coil, however I can't find any information on it. For anyone who might have any suggestions or anyone who has had this issue, did you replace your ignition coil, and if so, what did you replace it with? Do epoxy coils help with heat and mounting orientation? Any suggestions would be greatly appreciated!
