Firing Order for merc 8.1 HO
 

I've searched and can't find the info. I want to test each coil but I need to know the firing order
Twin 2014 Mercruiser 8.1

I did see that this is possibly the order 1-8-7-2-6-5-4-3
But it doesn't help me because I don't know which cylinder is which.

Any help is appreciated.

does this look right
[8 7]
[6 5]
[4 3]
[2 1]
Front of motor

That's all correct. The 8.1L is 2/3-4/7 swapped compared to a normal BBC.
