'64 Johnson V-4 60HP drive shaft problem PLEASE HELP

[KT64TM]

Hello all!!!<br /><br />I have a decent sized problem here's a little history:<br /><br />Last week I tightened the screws to my gearcase as it was leakin a bit. I also messed up and backed the shift fork pivot screw out. The shift fork is in 2 pieces (needs to be welded) and one side came out of the clutchdog. Saturday I took her out not knowing the above shifting problem. well i had to be towed in as it came out of gear and wouldnt go back. Sat. night i dropped the lower unit, and put the shift fork assembly back together, resealed it and put it back together, shifts like a dream. BUT my driveshaft apparently slid down and wasnt engaged in the crankshaft. so i dropped it again, put it back together and its fine BUT the woodruff key for the water pump impellor wont stay engaged as the shaft moves.<br /><br />MY QUESTION:<br /><br />how do I ensure the drive shaft doesnt slide up/down to keep the water pump pumpin???<br /><br />PLEASE HELP!!!

i have an old 1959 johnson 50 hp.i have dropped the lower unit more than i can remember.as far as that drive shaft moving???thats new to me.it should seat and seal in the gear housing with an o ring to seal the gears.it should also seat ans seal with an o ring into the crank.are you sure this is the original shaft?stupid question,but sometimes you never know.i also maybe totally wrong

yup its the original shaft. I know the "O" ring on the motor end is gone. I'll replace that tonight. as for the gearcase end im unsure if the "O" ring is there, if i were to replace both rings do you think that would solve my problem?<br /><br />::::shaft moving, causing misalignment of waterpump impellor woodruff key:::::

Re: '64 Johnson V-4 60HP drive shaft problem PLEASE HELP

id sure bet so.like i said though,it should seat in both ends without any movement.those orings will help it hold position

KT..... A 1964 60hp V/4 Johnson has a one (1) piece driveshaft that is a specific length depending on what shaft length the engine is.<br /><br />It is impossible for this shaft to "slide down" out of the crankshaft. It is also impossible for the woodruff key to fall out of the driveshaft/impeller slot.<br /><br />I'd appreciate knowing exactly what you're speaking of.

Joe,<br /><br />First off, forgive me if I use incorrect terminology. I'm making educated guesses as to the names of the various parts. <br /><br />If I install the drive shaft so that it is completely seated in the pinion gear (ie: resting on the pinion gear retainer) the notch for the impellor will be below the bottom plate in the water pump (unless for some reason my water pump housing is not correct. And it will not be engaged in the crankshaft. If it is supposed to rest on the pinion retainer when installed, i have a drive shaft that is about 3/4 to an inch too short. And yes, the woodruff key, if the shaft slides down enough for the key notch to completely clear the waterpump impellor, CAN get spun out. It happened last year also. (forgive me sir if I have offended you, that is definately NOT my intent ) <br /><br />For reference I used the shaft and nonserviceable lower unit from a Fat 50 and yes the shaft was the perfect length to engage the pinion gear down to the pinion gear retainer. Unfortunately, this is a long shaft engine and my 60hp is a short shaft<br /><br />I took apart the gearcase this evening, removed the propshaft/gearset, removed the pinion gear retainer and used the shaft to pop the pinion gear carefully out of the bearing. There was no rubber "O" ring on either end of the shaft. I put new "O" rings in place and re-assembled. The shaft is now supported in the proper position. My only concern is: If i hit a bump on the way to the lake, will the shaft slide down again??? we'll hafta see.<br /><br />If this doesnt work: would it be ok to put the appropriate number of washers/shims inside the pinion gear to equal the distance of play in the shaft???

Hi KT<br />You better hold on a mimute. I feel you need to investigate this problem more. There were two different lower units available for this model. The standard and heavy duty. I am not sure which one you have. If your gearcase splits at the center line of the prop shaft and the gearcase bottom/cap is sealed with speggitti seal, has 10 screws holding it to the top portion. You have the heavy duty gear case. The standard gearcase is also a 2 piece deal. the lower portion is more bullit like. the propshaft has to be removed from the prop end. It has 2 long bolts that hold it together with nuts near the water pump. This style uses a sholder on the drive shaft to index, this sholder is located under the empeller key slot. I am sorry, I have studied pic's of both units and can't seem to come up with a soloution. How ever I do belive you did not assemble somthing correctly or someone did not use the correct parts. Take your time and sort this out. O-rings alone will not cut it. I know this stuff is hard to describe, I'm looking at the parts manual and still sweat it. Try and post what type gear case you have. Maybe with the added info we can jog Joe's memory (not that there is anything wrong with it) a little.

OK i do have the heavy duty gearcase (2piece 10 screws, spaghetti seal [and silicone]) and i put everything back in there the way it came out. (I am a good mechanic, just not familiar w/ outboards but im learnin' It has performed perfectly up until now. (aside from worn dogs)

KT.... You did not offend me, but rather confused me. Right off hand, it sounds to me that you have the wrong driveshaft for that engine. I checked my stock and found that I don't have any left.<br /><br />The standard (short) deiveshaft for the heavy duty lower unit is #311088, and the long driveshaft is #311089, Both have been unavailable for some time but I'm sure that someone will have what you need.<br /><br />If you're not sure what length shaft you have, measure from the underside of the transom bracket (where that bracket sits on the transom) down to the cavitation plate (the plate just above the propeller), then subtract 1". If that measurement is close to 15", it's a short shaft. If it's closer to 20", it's a long shaft. Good luck.

I know its a short shaft engine. I bought a Fat 50 (unknown year) in pieces to part out for $25. So far its been a goldmine of interchangeable parts. The shaft for that one is about 5 inches longer than mine. <br /><br />In the interim, would it be plausable to use washers or something of the like to shim the shaft (place appropriate number of "shims" to equal the distance from the Pinion gear retainer to the bottom of the shaft) so i dont lose any time on the water?? You wouldnt happen to have a shift fork thats in one piece. mine is broken at the bend (possibility of welding???)<br /><br />Kevin
