Okay so I am about to take my boat out tomorrow, and I need to get all of my timing adjusted properly, along with my idle.  Here is what I am going to go for, with a MSD billet dizzy and a 750 cfm edelbrock:


Initial timing 10-12*
33* total at 3000 rpm
Autolite 26's gapped to .045
idle @ 1200 rpm
fresh oil change with 25W-40 Mercury oil

Does that sound about right?  What should I start my idle mixture screws at when adjusting?  Should I adjust the carb or timing first?

Thanks!

Sounds like a good starting point

Mine is 1200 out of water, 1000 in.
33 at 3000
750 vac sec holley marine
autolite 25 gapped at 42
Val race 20w-50
Try and keep you idle down as your adjusting the air fuel mixture....
