I've got the outdrive off the boat. I'm going to replace the driveshaft bellows, it appears to have been leaking. My question is, should I be able to turn the driveshaft by hand? (neutral, of course)If not, something is seized up. I've had the lower unit off to rebuild the water pump, and everything appeared to be moving freely.

Wow,<br />I am right there with you. Bellows leaked, replaced Gimble, and U-joints (lots of fun). Was working on the Water pump, all seemed to be going well, now the drive line will not turn, prop shaft still turns. The Bellows looks like it will be a real pain.

Re: Outdrive issues

Did you check for water in your gear oil? Usually water in your bellows means the yoke seal is shot and water will enter the O-D. Yes, you should be able to turn it by hand when out of the boat, even if it is in gear.See 'Halibut Junkie' post. J.............

Re: Outdrive issues

Shifting is done on the prop shaft so you will have quite a lot of friction at the input shaft

You've got to overcome the resistence of the Impeller Blades.......<br />They Don't Turn all that Easy,.... Especially a New 1..........<br />That's Also why a Tech would have the "Tool" that allows a Wrench to be used on the Splines.........<br /><br />I'm Obviously Not Sure you Don't have a Problem,......<br />But,.. Ayuh,.. They Don't turn All that Easy......

Clarification: I didn't say it was easy, only that it can be done by hand....J

Re: Outdrive issues

Not really..water in the bellows means the bellows have a crack/hole in it from sitting in the water

And I want to add that as you have had water intrusion, even though it isn't salt, I would pop for new bearing and whatever else in there. Pay me now or pay me twice later thing

Re: Outdrive issues

That the bellows is bad is not the question....A by-product of water in u-joint area is destruction of the yoke seal & gimbal bearing & u-joints, not always all of them, but the yoke seal is generally first to go.

Re: Outdrive issues

O.K. Here's the deal. I took the driveshaft out, and checked everything. Everything moved freely, and, no water inside. I'm sure the bellows is bad. I will replace. When I put the shaft back in and tightened the retaining nut back down, same problem. It won't turn. I backed the retaining nut off about 1/8 of an inch and everything moves smoothly. I pulled it again and found that one of the spacers is split. I'll be replacing it too. I'm thinking that I may need an additional spacer in there so that I can tighten up the retaining nut. What do you guys think? Sometime this summer I hape to tackle my engine coupler which is stripped. That probably happened because the shaft was stuck, right?

Re: Outdrive issues

That retaining nut is used to set the pre-load on the bearings. The adjustment should be done with the assembly on the bench, set up like in the manual, and using a lb-in torque wrench. If you don't have the manual, the tools or the understanding of how it all comes together, best take it to a shop, pay them $50 to set it all up for you. Else you could be buying a new drive if you get it wrong.<br /><br />Chris........

Re: Outdrive issues

I agree, I may be nearing the point where I have to take it to a pro. However, (I'm sure you knew that what coming!) I am trying to accomplish as much as possible by myself (with the help of the manuals and people like yourselves) for the satisfaction of learning how to do it and do it right. My merc manuals are on their way, I'm struggling with the Clymer's for now, I've got the tools, and again I really appreciate your help and patience. <br /><br />Here is an update; First , I think I caused some confusion about The "retaining nut" the book refers to it as a retainer. It holds the u-joint assembly in place in the upper housing. When I backed it off I was able to turn the assembly. When I removed it completely, I found that the metal outer ring of the oil seal was damaged. It has 2 "rips" in the metal that the universal is getting caught on. I will replace the seal and the o ring and put it all back together with a new nut (tightened to specs) on the gear assembly.<br /><br />I'll keep you all posted. Joe

Re: Outdrive issues

If the preload Just Changed on your unit,.... Someting Happened...........<br /><br />Is there ANY discolorization,.. At All, On the Bearing Faces ?????<br /><br />You'll need to replace the "split spacer",......And, You Probably need More Shims to get it to Spec.........<br /><br />Good Luck......... ;)

Re: Outdrive issues

Bearings look good, no scorching, everything is clean and smooth. Something happend that caused the 2 "rips" in the oil seal. Then when the the u-joint wouldn't turn the previous owner tore up the coupling. He told me he was having trouble shifting. He had stripped the splines on the coupler and wasn't getting power to the outdrive. Does that sound logical?
