Reply To: Connecting rod bearings, 1956 Johnson 30 HP

I think I’d go ahead and run it. I have a 1956 30 that has a million hrs. on it. When I had to replace the crankshaft (bad center main) I noticed some of the piston ring locating pins were missing. I could tell they had been gone for a long time, I left it alone and put it together that way. Some won’t agree with that, but it’s been running that way for yrs. In my experience, 50/1 ratio will wallow out the ring grooves on that motor. Saw it on a customers motor one time. I ended up changing the powerhead from all the wear on that one. Just my opinion..
