I have a 1967 Johnson/Evinrude 100HP.. How many CCA should be needed to start?

Thank you!

Rule of thumb: The best one you can afford. But not the wimpy cheapo ones.

My 67' 80hp cranks like nobodys buisness with a smallish 4 yr old 525amp voyager. It doesn't take a whole lot to crank it, emergency pull rope works great it's not hard to pull and get only 1 wrap around the flywheel.
