This was a great video, I had visions that the intake and half of the top of engine off. I am not the most nibble guy out there, but I can try ...... LOL JB

Thanks for making this!!

It’s not easy , just time consuming. Good job.

Thanks!

On a “stuck” rotor heat it with a heat gun being careful not to damage pick up coil. Pry up even and watch where the heat goes.

Hey thanks for the video
I’m having a problem with my 1998 with a 5.0 thunderbolt five ignition system
I stupidly remove the wires from the coil without seeing which one goes where would it be possible to make a video of the wiring at that coil?

[@glennederer4821]

If you look closely the cap is numbered and the intake manifold is numbered

Remove that round gasket from the intake carb, USCG don’t recommend that anymore

Curious to know what the underside of the distributor cap looked like. I.e. is there a visual way I could know whether it needs to be replaced?

Dist. Cap is labeled stamped into cap. Use mercruiser firing order.

If it hasn't been replaced in a few years just replace it. You will be able to see noticeable discoloration and wear on each electrode and on the tip of the rotor too. That wear increases the gap and affects performance.
