Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

I did find another article where someone is having the same type of problem. I still don't understand what the resolution was. The thread cuts off...

Anybody have any ideas?

Thanks!

Try shifting into forward, rather than reverse. Forward gives you the max clearance. As for the shifting lever. Can you be a little more precise in what you're having problems with? Getting the shift lever out, or some other shift linkage?

You might also try cranking the pull start. Could be the drive shaft is hung up in the powerhead. Sometimes a little rotation pops it down just that much more.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

iwombat: when I try to shift out of reverse, it pulls the lower unit back up into the motor, so I think you may have that reversed, but I'm probably wrong. I followed imported_F_Rs instructions, and they make sense except it won't drop more than about 1/4 inch, not far enough to get a socket in.

To get at the water pump, put shift in reverse, remove the four hex head bolts holding the gearcase on, pull the gearcase down about 3/4" and you will see the brass shift rod connector inside. Remove the lower screw from the connector, then the gearcase can be removed from the motor. The water pump will be looking right at you, around the drive shaft...

As for the shift mechanism, I'm having trouble trying to figure out how to remove the shift lever so I can remove the right side cowling, as in your picture. Do you by chance have a step-by-step of how you did that?

Sorry for being such a newb. I just want to be able to do this kind of stuff myself. I'm a computer programmer, so you'd think I could wrap my head around this kind of engineering, but I'll tell ya, I sure feel dumb now.

The repair manual I got is pretty crappy too. I eBayed a $5.00 manual on CD that is supposed to cover the whole lineup of OMC motors for the latter 20th century. It is so generic in nature, that it won't walk me through the most basic of maintenance functions. It looks like it was hastily scanned from a library, and each page was delivered as a seperate file.

I think I'd better break down and get a good manual, should I try to get the original for this specific motor? Is a SELOC manual the best, or is the OMC preferred?

Thanks again for your time and help.

P.S. - I'll try rotating the flywheel tonight to see if that loosens her up. Thanks for the tip.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

The OEM manual is by far the best. Removing the lever shouldn't be that hard. There's a keeper screw that needs to be removed and that's about it.

Part #72 is the only thing keeping it in.


And yes, now that I think about it, forward pulls it up.

That last image didn't capture too well. Let's try this one.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

I just replaced the water pump on my 71 Johnson 9.5 HP, and the manual does call for it to be in forward before you remove those 4 lower unit screws iwombat pointed out. When you pull down to separate the lower unit from the motor mount, the shift lever will move from forward to reverse, giving you clearance to get that 3/8? socket in there. You won't have to remove the shift lever. Also, like F_R says, make sure you completely remove the shift rod bolt. I can speak from experience on this! If you don't remove it completely, you won't be able to get the lower shift rod back in all the way and you won't be able to get it to stay in forward. See my thread at http://forums.iboats.com/showthread.php?t=202883. Ezeke included a nice picture of the shift rod coupler too. Also, make sure you take a flat-blade screwdriver and open up the space in the shift rod coupler so the lower shift rod will go in there easier. You want to make sure and get the bolt in the notched section of that shift rod, or it won't stay in forward. HTH, Steve

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Thanks for the advice, lexkyboater and iwombat.

I ordered up an OEM 1971 Evinrude 9.5 repair manual just to have around. I should have done that the first time I guess.

Do you guys think I should put everything back together, and start again by dropping the LU with it in forward gear? I guess I don't really want to take the cowling off if I don't have to, as originally I just wanted to inspect the water pump/impeller. Taking the cowling off was mostly inspired by curiousity, but I think I may be getting in over my head too quickly here.

At the bare minimum, I think I should change the pump out and get a new prop (based on my photos earlier in this thread) In every other way, it seems to run fine, although the upper end power is a bit low, but that may be because of the (damaged?) prop.

Opinions? Thanks again for all your help, guys.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

You really don't need to take the cowling off - at least at this stage of the game. Manipulate the shift lever to give you max clearance and try to shake it loose somehow. You should get about 1" or more of clearance when all is said and done. Certainly enough to get a socket in on that connector. It's possible that your drive shaft is really stuck, but that 1/4" separation is a good indicator that it's not bad enough to require extreme measures. Jiggle, shake and twist your way to LU freedom.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Yep - I would button it back down and try again in Forward. As iwombat said, 17 mph is impressive with that prop, or even a new one for that matter. Especially with 350 pounds in the boat. I wish I could get 17 mph with my 9.5 Johnson! But still working through some unknown issues causing it to bog at speed the moment. You might even check at a propeller repair shop for a nice used prop as I can tell you it's easy to put more money into these old motors than they're worth, unless you plan to keep it. --Steve

Edit: BTW, as iwombat is saying, pulling down on the lower unit with it even in reverse will cause it to shift to neutral then to forward just by pulling down on the lower unit. But, it's cleaner to start in forward so you don't have to excert much force. Starting to pull it apart in forward will gently move that shift lever to reverse just by the weight of the lower unit alone without any tugging if the exhaust tube and drive shaft aren't stuck.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

I'm going to amend my message about not needing to attend to the cowling for a moment. I forgot about that one picture of your midsection where it looks like it's taken a good hit and warped over the lower front shock mount.

You'll need to address that eventually. Taking off the side cowling is the only way to do that. A whole separate problem from removing the LU for a water pump replacement. But, I see it looming large in your future.

Take some pictures and I can guide you through the process.

You guys are awesome. I'll try again tonight. Thanks!

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Put the dadgum cowling back together. There's nothing to be gained by taking that apart. There is nothing wrong with it at least not visable in the picture.

Are you sure you have it in reverse gear? Did you twirl the prop to make sure it clicks in? If the lower unit won't drop down more than 1/4" in reverse, something is amiss. Could be the drive shaft is stuck in the crankshaft. You could have a serious problem if that's the case. Try a little more force, but don't break anything. It should drop down about 1/2" in reverse, just enough to get a thinwall 1/4" drive socket in there.

To answer another of your questions, the prop is bent.

All right, I just ordered up a prop. A Michigan Wheel 8.25"x8"

I'm almost sure it was in reverse gear (according to your first instructions) when I attempted to drop the lower, but others are telling me the manual says to start in forward when undoing the 4 LU bolts. The action of pulling down the LU is supposed to pull the gear lever into reverse, i guess.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Oops, my bad. I got it bass-ackwards. The shift rod needs to be pulled upwards from the gearcase (forward gear). Then as the gearcase is pulled downward, the shift LEVER at the powerhead goes into reverse positon, but the gearcase stays in forward.

Sorry about the confusion and crummy advice.

 

[iwombat]

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

No worries. Sometimes free advice is worth every cent you paid for it. Even when it comes from good sources.


That's a pretty easy mistake to make. I think we'll all forgive it just this once.


Now, sit back while I top it in some other thread.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Got the new prop. Put it on, no problems. Should I be using grease or cleaning the axle off when putting on a new prop?

Alright, so I buttoned her back up, threw her in forward, and undid the four gearcase screws. It still only dropped down about a 1/4" inch or so. I pulled pretty hard on it, also gave it a few sharp whacks with a rubber mallet. No go.

I also noticed that the gearshift didn't want to go all the way up into the reverse position when I pulled the gearcase down. While the gearcase is dropped down, I can shift it between forward and neutral, but no reverse.

I went to snaps some pics, but my battery was dead in the camera. I'll try to get some on here as soon as I can.

any updates?

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

Finally got some pics.

Here's the gearcase/LU next to a ruler. I get about 1/4" of clearance. barely enough for a screwdriver much less a socket wrench. (sorry for the crummy photo)

Here's a pic of the gearshift. As you can see, it's barely past neutral with the gearcase lowered as far as it is. At this time, the gearcase is in forward.

I've tried a couple more times to pull the gearcase down more, but I'm afraid of breaking something. Is there something other than the connecting rod that holds these two parts together?

 

[iwombat]

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

There's only three things that could be hanging you up.

Shift rod
Drive shaft
Water tube

Since it moves 1/4 inch I think we can rule out water tube. Have you tried giving it a couple of pulls on the pull start? I think your drive shaft may be what's hanging you up.

Re: 1971 Evinrude 9.5 Sportwin Tilt Problem

I've tried pulling it, and the prop moves as if in forward gear. Doesn't seem to make any difference in lowering the gearcase.

Just to reiterate, I'm simply trying to get the gearcase down another 1/2" or so so I can get a socket in to loosen the shifting (connecting?) rod clamp. It is a flathead screw with a socket top. I've almost stripped the head with the screwdriver, now I want to try undoing it with a socket. I've also tried spraying wd-40 into the screw to try and loosen it, but to no avail.

Thanks again for the help!
