Guessing my next move to replace the distributor and rotor?
Look like the one I should buy?: A.A Tune-Up Kit Distributor Cap Rotor for MerCruiser GM V8 Thunderbolt IV, V, HEI Ignition System 18-5273, 805759Q3 https://a.co/d/iQcMcER Im guessing your next move is to slow down and develop some trouble shooting skills. A harbor freight test light goes a long ways and they start at like $3.99 https://www.electricaltechnology.org...lor-codes.html |

Okay.
turn key to run. Put your volt meter to the ignition coil leads. Is there 12 volts present ? |
From the looks of that distributor, you may want to replace it.

You already know you don't have spark, you just don't know why. Call your local auto parts store and see if they can test your module.

Just pull a spark plug wire off and crank it over?
Furthermore….your coil looks like this. Looking at carburetor from frt of engine, it is just behind the carb to the right.Puple wire terminal is + and grey wire terminal side is -. https://cimg8.ibsrv.net/gimg/www.off...67e653e71.jpeg |
