Re: 1957 18 Johnson

I thought that might be the case. I guess I’ve never had one with the extra letter. I just love the FD motors…. lots of power in a light weight package.
One other question while on the subject of this motor, what would be a good 2 blade speed prop for a Model F Alumacraft and a 120 lb. boy at the controls? I know there’s been discussion on some different prop/pitch options used on the 18. Just curious if someone has a suggestion. My son has been running this motor on a Deep C using a 9 pitch with about the right amount rpm’s at WOT. I’m sure we can come up a bit in pitch when we move this same motor over to his new Model F.
