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

Frank and t2stroke,

Thanks for the advice. Who knows why it was taken apart and put back together without any of the innards. Lots of hose clamps on that S shaped hose going to the starboard side cylinder bank so somebody was trying to bandage it up. Maybe like me they didn’t realize that the thermostat will come apart with springs flying everywhere like a Jack-in-the-Box when you take it off. At least I found all the parts from the one off of the donor motor I am using. Will try and backflush since I have it apart anyways.

Frank, I have two cats at home. I’ll see if one of them would like to take a run through the passages and check for blockages 😉
