Should I worry about this driveshaft?

After reading some of the comments from Skibum's thread about his drive shaft, I started thinking about the dings on my drive shaft. Is this something I should be worried about?

Randy,Skibum shipped his shaft to General Prop.so they could duplicate his double taper.
1"x541/8" They will drop ship to you,and you use my dealer number.........226.53 plus shipping. single taper 174.03 They supply C/C with their shafts and couplings......boat dr

there he goes again more sells sh*t, ignore the question and send the stuf to me,

please offer something beside a sales pitch d*ckhead DOC


Randy don't get excited about the shaft the saftey collar is slid down against the packing gland there should be a small gap between the two and the two marks look like dimples for the set screw of the saftey collar.

I hope you replace the section hose, the dimples where drilled in the set screws won't create a indentation like that, they mar the surface but won't create a recess like the one shown. The one dimple furthest from the packing gland is what you should line the saftey collar up with remove the set screw so that it is exactly over that spot it will prevent the collar from sliding on the shaft if something goes wrong.

Excuse my ignorance guy's,is that collar on there so you don't lose the shaft? My 68 does not have one,would it be worth while to have one.I've never had the shaft even come loose or heard of one coming out.

79, I didn't replace the piece of hose. That would require removing the entire shaft. The piece of hose seems fine, it has a little bit of a twist to it but is not torn or damaged.
Are you saying that the collar should be up at the top where the top dimple is? that seems to be too far away from the packing gland.
I agree, I don't think the set screws would cut into that shaft, who the hell would take a drill to this shaft? I agree, that is what it looks like. I'm not sure what if anything I should do about it. I would rather wait until next year to do anything with it. Unless it is a danger or possible big problem... I will try to take a picture tomorrow to show the whole thing.

Close up of the dimples:


I moved the safety collar up to the lower dimples that seems to make sense. Is this right?


first pic came out a little dark, sorry

does the hose look alright?

79- I have it pretty tight. I think I do have four rings of packing in. is this not right? I thought I had read that I should put as many in as would fit... should I take one out? Is the safety collar in the right place? I think maybe it should be closer to the packing nut

thanks

randy you have the collar in the right place the second to last pics shows the witness mark on the shaft where it should be. By witness mark I mean the discolored part of the shaft not the dimples. The set screw hole should line up right over the dimple closest to the packing.

Witness mark?

I don't think the extra dimple is going to be a problem, it could serve as a fatique stress concentration in bending if the shaft was bent or ou were very out of alignment but you wouldn't be driving it around then... nice pictures, great way to get a good answer.

"Witness mark", refers to any previous mark made on a part that would help you figure out how to re-a$$emble it. In this case its the mark made by the safty ring as it sat on the shaft.

three is right just tighten it down as tight as you can get it then when your in the water let it set for about 10 minutes and re-adjust the packing gland, You need for the rope to soak up somewater and they will soften and you can tighten it more. Just be sude and tighten down the jam nut when your all done,

Hey,

I replaced my shaft packing with the gortex packing. I used three rings and snugged the packing nut hand tight. I watched the packing and I did not notice any water dripping. I rode around for a bit and I checked again. The shaft was hot. When I poured lake water on the packing nut it steamed. I unscrewed the nut until it was almost off and water was dripping a steady stream. I let a good bit of water drip until it was cool. I tightened the nut and it was just tight enough to touch the gortex packing and it was dripping a few drops a minute and I turned it 1/4" and it stopped dripping. I ran the boat for and hour and I checke the shaft and packing nut and it was fine. It was not even warm.

Is the gortex ok after being heated?

Hey,

I guess the water needs to flow into the packing nut to lubricate it. I must have had it too tight and it could not get all of the gortex wet.
