Mercruiser Distributor Cap replacement 5.0L 1999 thunderbolt

[afirststep]

First time replacing replacing distributor cap on a Mercruiser 1999 5.0L 305CID with Thunderbolt ignition.

I followed the markings on the distributor cap for the wires. I used the REV markings and looking from the top of the cap, the firing order is 1-8-4-3-6-5-7-2 reading counter clock wise.

The engine did not start. I looked in the manual and the manual shows a clockwise rotation with the same firing order. It also shows the #1 cylinder on the left. So the diagram must be looking from the top?.

I am confused. Which is right the cap (CCW rotation) REV markings or the Seloc repair manual diagram (CW rotation)?

Wife dumped the old cap and rotor (looked like a spider!)

What am I doing wrong?

Thanks, Andrew

The cap on the carb says left rotation, so I followed REV.

Do I use the STD or REV markings on the cap? The diagram in the book follows the STD markings. You seem to agree with the STD markings.

Just trying to get things right or is it left?

Thanks,

Andrew
