Re: any harm in back flushing ’67 Johnson 100 hp?

Frank and fileetwin,

This is an old teleflex drum system. I am guessing I unbolt the drum from the shaft and flip it over to make it steer correctly. Took my heart rate a couple minutes to get back to normal after I almost ended up on the rocks. Will have to experiment with trying different holes for the motor trim. Was running it on the middle hole, seemed to plane well. Also, will take a look at the pitch of the prop. Tops out in the low 30’s. Thought maybe I’d get a little more speed running 100 hp on an 800 lb hull. Ran the oil at about 40:1. Runs well at speed, idle needs a little work. Is there a low speed jet on this motor or is the only adjustment the slider bar on the port side of carb?

I have 6 boats from the late ’50s-early 60s that I am redoing. Really had fun with this Lone Star pocket cruiser on the water for the first time. Yesterday was 70’s, rest of the week is cold. Hope to get at least one cruise on the Chicago river through the downtown skyscrapers with my wife and kids before It goes into storage.

Steve, if I can figure out how to post pics I’ll put a couple up.
