    Stern drive woes

    Any of you folks used one of these aftermarket replacements for the bushing/seal? If so, do you still put the rubber gasket and SS washer on top?

    Stern drive woes

    Yeah, I eyeballed it and it looks lined up properly. Probably gonna get a new shaft, as I did get against it with the dremel and scuffed it. Again if anyone knows that thread size appreciate a heads up. Thank you all for your advice so far on this thing.

    Stern drive woes

    The dremel did the trick. I think the housing was spared, but I’m gonna need to chase the threads, and clean up the chamfer. Anybody know what size threads these are?

    Stern drive woes

    Thanks Kenny that’s great info. Here’s what I’ve done so far. Drilled a bunch of holes. Then tried unscrewing with large needle nose, twisting with a wrench while tapping on the wrench. No joy. I’m now working on it with a dremmel. Your method sounds worth a shot.

    Stern drive woes

    The big issue right now is getting the shift shaft bushing out (the top corroded off). Any tricks or tips are appreciated. I think I might wind up drilling a bunch of small holes, and then just bust out the pieces. Only problem with that is that is going to result in lots of metal going into...

    Stern drive woes

    I didn't ignore it. I responded to it, and it was good advice. I still was not sure, from the information provided, whether there still might have been issues. It's always good to have someone who knows to actually put their hands on it. That gave me the confidence that it was in fact good to go.

    Stern drive woes

    So I got advice from my resident expert - my brother. The driveshaft is fine. I didn’t realize the direction of the thrust on this. It’s upward. So that’s one question answered.

    Stern drive woes

    So how do I get that bushing out of there now that it’s busted off? Also, I double checked and when I lift up on the shaft it’s pretty darn smooth, and essentially all the play is gone. Is this normal? If so, what am I feeling when I press down and turn? Anybody got any advice on the upper...

    The wobble bothered me too, but again, I don't know how much is tolerable. I'll pm you for those videos. Thanks.

    Stern drive woes

    Bt Doctor, yes, I noticed when I pulled up on it, it was reasonably smooth. But the logic in my head was "well, that's just because I pulled the bearing up off the race, so there's no contact anymore". By the way, the unit has never had any oil leakage issues, had good oil fill prior to...

    Stern drive woes

    Another thing about the shift shaft bushing. The stainless washer that goes on there is deformed. It looks like maybe the unit was forced back onto the upper housing with the the shaft coupler misaligned and it deformed the washer and perhaps broke the bushing. I don’t know. As far as I know I’m...

    Stern drive woes

    Hi all, Among the things I didn’t think I’d have to worry too much about, I’m now finding that my stern drive is perhaps in need of a lot of work. This is an alpha 1 gen 1, around 1984. First thing is the lower unit. Ive removed the water pump and when I turn the driveshaft I get a sound that I...

    Output shaft slop

    Thanks everyone for the replies. I guess I’ll need to find me an alignment tool. Meanwhile here is the output hub. It looks pretty good to me. I think the alignment in this system was really good, and wear has been nominal.

    Output shaft slop

    Thanks marc c. I'm thinking the same thing. I think one of the important things would be that there's no visible difference in the profile of the splines in the areas just forward and aft of the zone which engages the hub. You can see that zone, due to the shininess of the thrust surface on...

    Here’s a pic of the shaft splines.

    Output shaft slop

    Oh, yes. Flat. As mentioned, I don't see any evidence of undue wear. It's hard to inspect the power hub splines, but I'll clean them up and have another look. I'm wondering if there might be a spec available on the "backlash". I can't find anything in my service manual.

    Output shaft slop

    Not sure I follow the question. They are not absolutely square, they are slightly tapered (typical splines). Maybe I’m missing the question.

    Output shaft slop

    Seems like my last few questions are about how things fit. Question now is about output shaft fit. Is there any rule of thumb or guideline about how much play is allowable in this joint? I know the right answer is probably “none”, but this unit has operated fine for years and I don’t think...

    Bell housing side play

    Thanks, but it looks like it's actually item 11. No thickness is given on that item that I can see. I'm going to order some anyway, maybe the pins too. It's only a few bucks.
