Re: 1959 35 hp evinrude longshaft to shortshaft

Would the driveshafts be the same diameter and spline count? Could I take the two driveshafts to a machine shop and say "cut the keyway like on this shaft in this shaft at the same position" ? Is it possible the coolant flow on the cutter used would not change the hardening of the shaft? Thanks for any input. I looked on e-bay and kijiji and could find no short driveshafts, so I am trying to come up with other alternatives! Thanks for any opinions!!

I'm not 100% sure, but I think the length may be a tad different. Splines should be the same. If you do machine a key slot, and use plenty of coolant, it probably won't work harden. Otherwise, that material will work harden.

I'd take High Trim up on his generous offer.

I have noticed OMC could be tricky with that. To the untrained eye, they look identical. Then you bolt up the gearcase, and the new one is 1/8" too long, either putting pressure on bearings, and seizing up the motor, or it simply will not bolt up at all.

Another reason I can sometimes have difficulty putting a positive ID on a drive shaft. I have a box full of them. If I were smart, I would have labelled them as I went, but Im not that smart.

Thanks High Trim! I am a fellow Hamiltonian which should make things easier! If you want to give me a call. I would be happy to buy a driveshaft off you if we can find one that fits! Thanks for everybody's help on this problem! Happy and safe boating to all! Ask for Steve

Been looking through parts this morning. I have only found the early style like from your '57 so far, but will continue the search! I would delete your number from the main page and send it in a PM.

Update. I managed to find a '59 short shaft for 75 $ and have done coils,points condensers,impeller and cleaned the needles as well as replaced the fuel and sparkplug lines. Seems to run good in a barrel. Sold the '57 for 20$ to a member on here!! All is well!! Thanks for all the help
