I have been reading through 4 pages of threads that came up in the search tool for piston to cylinder clearance. I have a Johnson 150 made in 1980. I need to bore at least three cylinder's and I have located some used pistons. Trying to find what everyone is running. I have seen threads that say .004 and others that say factory reps go for .009 that's a pretty big difference. I currently have .007 on the three that I hope not to bore.
Thanks for the help, Randy
