Does anyone know the correct firing order for a Merc 850 6 cylinder? I have been having trouble with it dieing when I shift into gear. It idled a little erratic but it revs out of gear just fine. So I decided to do a tune up as I had it at the lake the day before so i wouldn't imagine its anything major. I did new plug wires but didn't write down the firing order for some reason. There are 3 different firing orders stamped into the cap but none of them are working im not sure if I'm reading them right 🤔. Any other insights into the dieing when shifted issue appreciated as well

Often times you just need to open the LOW SPEED mixture screws an 1/8th turn at a time to get rid of stalling.
