Hi there, heres one that has stumped me!

After quite a few months sitting idle i went to start my ss but have had loads of dramas.
I have fresh fuel, charged battery and now a new coil but seem to have a problem still.

I gave up on it after quite a bit of cranking and let go of the key and it jumped to life! anyone else experienced this? once it was going it ran fine and would start repeatedly but would only do so after letting go of the key. it is also running very sooty water even after 10 mins on the hose.

any ideas?

Faulty ignition switch.

I agree, ignition switch is where i would look first. Sooty water is from the unburned fuel loading up.

had the same in an 85, Not enough voltage to the coil while cranking starter. Check the Wire Loom connector back by the rear and also positive battery cable end was bad. Seems better now

Hey thanks for all the replies!

I pulled everything apart and gave it all a good brighten up with some emri paper. It was still cranky and would only start occasionally after I had let go of the key. Once it was going it ran well though. I was contemplating changing the ignition module or distributor as its a converted presolite dizzy with a pertronix ignitor and I had read they can cause dramas.

Before I did that I got a new ignition switch and after a couple of floods it started. Once its been warmed up it has now had many starts with the key and seems to be causing no problems. I'll leave it until tonight and try it again as I'm not keen on having to paddle it home so I want it to prove some reliability on the trailer.

Thanks again for your help. Not many old mastercrafts here so help can be quite thin on the ground. Really appreciate it!

Ok so turns out I talked too soon! It appears that its the ignition module that is putting out a really weak signal inconsistently.

Anyone recommend anything to replace it with? It is a presolite distributor with a pertronix module. Im running a MSD blaster 2 coil with no ballast resistor. 351w PCM LH rotation.

Buying things in the states rather than here seems to be quite economical and you guys have been doing specialised marine stuff better and longer than us.

Any help is appreciated

Personally I would swap out the petronix for a Mallory E-Spark Kit. I have read numerous times that petronix has failures. This is the kit I used http://www.summitracing.com/parts/maa-9-26902/overview/, amazon slightly cheaper http://www.amazon.com/Mallory-Marine-9-26902-E-Spark-Kit/dp/B003BYRAX2/ref=sr_1_1?ie=UTF8&qid=1380987081&sr=8-1&keywords=9-26902I I also use the MSD blaster Coil 2, the Mallory requires the ballast resistor so that would to need to be reinstalled. Or just replace the entire distributor out for a new unit http://www.summitracing.com/parts/maa-ylm554cv/overview/make/ford Which I did when I modded my engine, but I used this dizzy for the optical eye which is the same that is used in the espark kit http://www.summitracing.com/parts/maa-9-26501/overview/make/ford

Hey thanks for those suggestions!

I think I will go with this

As you cant readily get presolite parts in Australia and it is weeping a little oil into the distributor I imagine its about time for a new one anyway.

I will be running the MSD blaster 2 coil in it. Do I need to rewire the ballast resistor in, get a new ballast resistor, or can I leave it with the ballast resistor bypassed?
