..."The original 5 pin ignition modules needed a ballast resister in order to reduce the voltage to the unit the newer 4 pin do not." I do not believe that is correct. In fact, I know that running the switch box on a full 12 volts will cause it to fail after a period of time. Both of mine ...

I would go POSTAL in a hull that topped out at 10 knots!

.." Like the hull got sooo stressed when it hit that bridge pier so we welded it man"

How much damage was done to the bridge? Some, I'll bet!

My experience may not help out here, for I ran over sized props (17 x 15 four bladers). I found the most economical cruise was at around 2,500 rpm and 18 to 20 mph (depending on bottom cleanliness and other factors) burning 9.5 gph per engine.

Yeee-hah! Gonna be a good year.

Congrats.

That's the Hall effect sensor. Replace it as well--they are cheap--and it HAS to work!

Jeff

PS: You should see some resistance with a meter across the leads to it. If it's open circuit, that's the problem.

The "I" terminal on the starter solenoid sends 12 volts to the coil during cranking. Put a meter on the '+' coil terminal and see if the 12 volts gets there. If it does, and there's still no spark, I suspect the Hall Effect sensor in the distributor (or some other item) is faulty. Jeff PS:...

Amazon lists the ZDDP additive. About 16 bucks.

Ditto on the one wire alternators. (The only knock on them is you sometimes have to 'boot' the throttle to get them going, or they may drop out after long, slow idling. Another 'boot' and they're back at work.) One of the wires going to the old voltage regulator will be Hot in key ON. You need to ta...

The Autozone (and other) units are the SAME. And don't worry if they ask you for a "4 or 5 pin" unit--they work the same.

Jeff

PS: Suggest you buy two and have a spare on hand.
