distributor change
 

what would be a good replacement for merc thunderbolt ignition.something that might not have a module or built in the side of the distributor.350 sb

I used the Mallory one, Everything is built in, kinda like a uni-lite, but has the magnetic pickup instead. I bought mine remanufacured off Ebay, but I think Jegs, or Summitt sells them.

is it marine?

YUP, get the Blue one, has a screen in the base for spark arresting. I will see if I can find a link.

here ya go,

The Jegs description says "utilizes Hall effect triggering". Is there an option for magnetic triggering?

mallory sounds good any other suggestions?do i use the same coil?

I believe the stock Merc coil will work, I replaced mi dist. because some idiot had put an automotive HEI in there, and I did not have a coil, so I just bought a stock replacement accell coil.

MSD makes a marine distributor with a magnetic pick up, only a little more than the Mallory at Summit

I'm running the Crane Hi6 ignition box with a Crane coil and MSD billit distributor.

The Hi6 is nice because it has the Merc ignition advances programmed into it. Just pick one with the dial. It also has a dial for the built in rev limiter. Adjustable in 100 rpm increments. Easy to use, easy to hook up.

I'll be using the same set up with Crane HI6, coil and MSD distributor.

Seems all so simple.

Scott :D

ok guys im not done. if i change to the mallory and due away with the thunder bolt has module advance what do i do? does the mallory need an advance or is that just a timming issue?do i need some type of seperate module or just the dist and coil.

The Mallory is all self enclosed, just wire it up. Module is inside the distributor. Very easy to install. The only other things you will need is the coil, and I put a ballast resistor on it. Here is the wiring diagram for you.

thank you rchevelle thats what im looking for. where did you mount your coil?

I used the stock Merc Coil mount, if you dont have one, you can just get one from Jegs/summitt or someone like that, and mount it on one of the intake bolts. Unless you plan on using the newer flat type coil, you will have to find another location.
