Hello,
I just rebuilt a 1971 Johnson 4HP. 4R71D
I was wondering what I should be targeting for a "lowest" or "trolling" RPM. It seems to be the slowest and smoothest combination is at 675.
Thanks,
Sal

That is about the best you are going to get, give or take a few rev's.

Great thanks. I was guessing about 600-700 rpm.
