1972 65hp johnson no start (timing?)

englee1 I just purchased a 50th anniversary 65hp Johnson that has not been run for 5 years. I brought it to a mechanic wo replaced the shifter cable, cleaned the carbs & got the motor running...he & I were amazed by the great operation of the motor. I took the m 2001-08-12
Big Four Unless someone changed the timing it will not move. Have you checked the battery cables? Take them and bend them every 4-6" and listen/feel for a crunching. All it takes is a pin hole for water to get in and corrode the copper wire. The cables may look swollen where they are corroded. 2001-08-12
englee1 Thanks for the recommedation Big Four.

I did try this earlier, no problem found.
Also I jumped the battery directly to the starter terminals....with the same result.
Any other suggestions?

adrian bick Lower unit binding ????. Remove lower unit and try to fire it up. 2001-08-12
englee1 Thanks Adrian, will give it a try. 2001-08-12
thirdm hey englee1...

i had the same problem w/my Johnson ('71 100hp). like you i bought a new starter - i bought a new selonoid too. everyone kept telling me it was a bad ground - but jumper wire after jumper wire said it wasn't. i also took a wire brush to every connection on the engine. then i went and bought a new battery cable set. this is a pre-manufactured set from OMC that comes w/the ends soldered on - heavy gauge wire, etc. it didn't look like any thing was wrong w/the old ones, i did the crinkle thing too, they still look good. but they didn't turn my engine over like the new set. only problem is they cost $50 for the set. hope i could help.

p.s. lay off that starter until you figure out the problem - you'll burn it up - and a new one will cost a fortune (if you can find one)....

englee1 Thirdm, I should probably give that a try.
I have already jumped my battery directly to the starter with no luck, same sluggish performance. Do you think that eliminates the battery cable problem or could the cables still be an issue? Thanks for your help.
