mercruiser 4.3 ignition

[Rubenster619]

I have a 4.3 alpha one mercruiser. My ignition amplifier went out. Can i swap my whole distributor to a regular automotive one and still run the same?

 

[gonzo]

No, because of safety issues. Automotive distributors are not spark protected. A new part will cost less and be simpler. What is the year and what is it doing?

 

[Rubenster619]

Ok i still have distrubutor with sencor can i only use a regular ignition module to control it

 

[gonzo]

What year and model is it?

 

[Rubenster619]

The boat is a 91 larson the engine is a gmc 4.3 mercruiser alpha one

 

[gonzo]

So that is the one with the small coil and two plugs into the side of the distributor.

 

[Rubenster619]

Yes can i install that one instead of the iv thunder bolt ignition amplifier

 

[gonzo]

Can you take a photo of your ignition system?

 

[Rubenster619]

This is the problem i just wanna double check if i can replace that with a regular one from a normal gmc engine instead of this and keep my originial coil and distributor that belong to tge boat and have no problems

 

[Rubenster619]

It cranks but wont start and i live this is the issue

 

[Rubenster619]

Did you run through the Mercruiser ignition diagnostic checklist? How did you confirm that the module is bad?
