I contacted edelbrock at lunch and they said for the 1409 that 3psi @ WOT is the minimum and 6.6psi is the maximum .
I've always had 5-6 psi @ WOT and never seen it drop below 4.5psi . So this has got me wondering . Brand new carb

Got the ballast wired as it was when I got the boat , and how Mallory states 12v+ at coil positive , spark is a lot better but coil is still hot . Like 185 degrees to be exact and the ballast is not hot at all . I thought I should be seeing a voltage drop ? Am I ?

I found a wiring diagram online finally ! So I'll check it out this weekend on the water hopefully that fixed it

That's awesome Lively. Sorry for your troubles, but your diagnosis and videos will certainly help others who need to work through similar issues. I rebuilt my engine this past winter and thought about removing the ballast resistor when I rewired it all, but then discovered that some Mallory electronic distributors still required the resistor. So I left mine as well.
Glad you've got it running right. It really sounds good.
Thanks Titan ! Sometimes I over look things and should have looked at the elec print and wired it up that way . Tomorrow I'll know if my findings were correct . And I changed my prop out last night after hitting stump and ripping my new one up http://img.tapatalk.com/d/14/06/01/qahuhy3a.jpg

Ouch. I recently had a similar issue when my prop shaft slipped out of the tranny and the prop hit the rudder. It's being repaired now.

i took a old one i had that had some dings and chips and put it on a belt sander and smoothed it out and leveled .. no vibration at all .. boat ran great today but im thinking its time to upgrade to a electric fuel pump .. i ran the engine for 4 hours non stop and at the end of the day it felt like it was missing and the idle was at 5-6 so i adjusted it to 999 rpm and cleaned up .. but i later noticed that fuel pressure was not at the rail during restart and had to crank the engine over 4-5 times to build it back up and fire it .. once it started it ran fune and fuel pressure held at 6.5psi .. but this guy is happy the boat runs !!!
Hey sorry, meant to follow a bit sooner but got distracted. Glad you found the O.E.M. diagram. And very glad you got it sorted out.
Just to confuse things, did you ever run across this Mallory diagram?

I imagine it's figure #1 that you have going.
Best,
Grover.
That's how I wired it first ,and it didn't don't anything different just had a weak spark and voltage never dropped , but PCM wiring diagram shows dizzy wired to pos + of coil and then coil to ballast , choke on 12v side coming in with S term to ballast .
