Has anyone had to replace the side or center mounts in a 9.5? How difficult?

I have at least one bad mount. Dealer isn't sure it's worth opening up to see given the complexity of the process and the price of replacement mounts, especially if there's more than one broken.

Motor is a 1971 that I bought new and have cared for well. Its starts easily and runs well with new points, condenser, impeller, etc.

Any advice?
thanks

Re: 9.5 hp rubber mounts

Grab hold of the flywheel (not running, duh) and see if you can move the whole powerhead fore and aft. A "rubbery" feel is OK, flopping around loose is not. That would indicate a broken upper front mount, unfortunately very common in those motors. The labor to replace it is very significant. It is a big job, and definately not for the novice without mechanical aptitude. But if you want to try it, by all means start with a factory service manual.

The side mounts may or may not be bad. If they are, the labor is the same.

Re: 9.5 hp rubber mounts

The motor is still at the marina, but a mechanic friend at the lake last summer said he thought it had a broken center mount. Up there (canada) they could not longer get parts, but here we can. At what price is the issue. It would be nice to have xray vision to know how many mounts are bad. That's the issue of whether this repair would be just expensive or out of hand.

It does run this way, it just feels pretty bad at the tiller. I guess its a matter of sucking it up and paying to fix it or replace the motor, perhaps keeping this as a back-up, since it still runs well.

Re: 9.5 hp rubber mounts

The mounts are listed as no longer available from BRP. The last price for the side mounts was 40.40 ea. They don't even show a last price for the front one. Try sea-way.com

As I suggested, the big issue is what he is going to charge you for the labor.

Re: 9.5 hp rubber mounts

I have a 1968 9 1/2 johnson, the mounts were so bad in it that it flopped around while running and would mess up the thottle linkage. I took it apart and used rubber cut out of the sidewall of a tire to glue up some new mounts. I don't know what the old ones looked like but the ones I made with tire pieces and shoe goo seem to be working fine so far, I've only used it for around 20 hours since. I hate to see a good old motor be junked when a little backyard engineering can make it work. It was a couple years ago that I fixed it, wish I could remember all the details, I just looked at where they needed to fit and guessed how to make them. Good luck, you may have something left of the originals to work with for patterns, the mice ate mine up good just rubber powder left in there. It wasn't easy to take the housing apart but can be done with some patience. Good luck at whatever you try.

There's some vintage parts place where most of this stuff can be found, but at a premium, according to my local marina.

I'm intrigued by the home made idea.

You mentioned taking the lower housing apart, which makes sense. My marina guy (not the mechanic, however) said something about having to pull the powerhead, which i found surprising.

thanks for the input. Further thoughts welcomed.

Re: 9.5 hp rubber mounts

The whole power unit floats on those rubber mounts, inside the clamshell affair that goes from the motor cover to the water line. That clamshell has to be split apart to shuck out the power unit. Ive done many dozens of them and could do them fairly quickly. But the first one will have you cussing. That's why I said you need the manual.

I talked more with our local OB mechanic. Though he's been around and does good work, this would be his first 9.5 hp rubber mount replacement/repair. Believing it to be the upper front mount, he planned to remove to power head so he could reach in there and replace it.

It's probably only that mount, but I'm worried his approach might not spot other trouble and it might take longer (but I'm not sure).

I'm thinking I should try to find someone who has done this repair before. Agree?

BTW, I'm in central New York, if anyone knows a good place to take this project.

thanks.

You can't get the powerhead off without shucking the whole thing out of the shell. I'd do it for you if you were about 1300 miles closer.

Re: 9.5 hp rubber mounts

Sounds like I need to find your counterpart closer by. If I understand you correctly, you need to remove the "clamshell" to get at the mount and to remove the powerhead, and that removing the powerhead is not necessary for removing the clamshell and replacing the mounts.
eh?

BTW, we're at peak color now. THis really would be a fine time for a vacation in CNY.

Re: 9.5 hp rubber mounts

That is correct. The powerhead, midsection and lower unit will all come out of the clamshell in one piece. At that time you can access the mounts.

Re: 9.5 hp rubber mounts

Thanks for that clarification. If understand it correctly, these mounts connect the midsection and lower unit to the clamshell. Unless they bolt through the clamshell, they would seem to make removal and reattachment of the shell a bit tricky.

Re: 9.5 hp rubber mounts

They do bolt through the clamshell. Removing those bolts is part of the procedure to split the shell. You can see the side mount fasteners, acorn nuts on the sides. The front fasteners are also visable, slotted or hex head screws on the front. But just taking those out won't get you anywhere...it still has to come out of the shell.

Re: 9.5 hp rubber mounts

That makes sense. Thinking more about it, I suspected those acorn nuts I've seen all these years might be involved. And yes, I understand how the shell and other unit would need to be separated to get at everything.

I'm thinking I'll either locate someone with your experience or get a service manual and have a go at it myself. I've got all winter ;-).

If it's the latter, can u suggest source(s) for a service manual?

Thanks for all your help with this.

Re: 9.5 hp rubber mounts

No doubt about it you need a genuine Factory service manual. outboardbooks.com holds the copyrights on them, so they are the only legitimate place to buy a new one. However, there is e-bay. In fact there is one there right now. Go to e-bay and search for 250178199043 It is for a 1970, but they are the same as your '71.

I won't bid against you. Even though I though about buying it.

Re: 9.5 hp rubber mounts

With shipping, the price difference between one and the other isn't big. From outboardbooks.com I'd get the manual matched to my motor year, but possibly photocopied vs. original. Not sure which way I'll go. Thanks for your consideration.

Shop manual purchased on ebay is in the mail. Here goes nothing..... Expect a new post, once I get started and likely lost.
Thanks all for your help here.
