1965 Sportwin 9.5 - Shifter issue.

[narnsmarnq]

Hello All,

I was reading a lot over the last couple of days, but can't seem tio find a answer so...

I got an (almost) free 1965 Sportwin 9.5. Throttle inkages were all seized, coils are shot, etc. I have a repair manual, so I'll muddle through and see what the total damage is.

However, I have a question I can't find a answer for in the repair manuals, the shifter won't budge. I haven't had the lower leg apart, but the prop staft truns freely and the engine will pull over. I am wondering if there is some kind of interlock that prevents shifting, a button that has to be pushed, anything obvious that I may be missing that would prevent shifting. The shifter is the flat horizontal handle kind that moves up and down, not the vertical shifter.

Should the above not be the case what would be a nesxt reasonable step in my investigation? I'm not sure how the shifter works (I think it employs a simple vertical movement of the shaft), could the drive shaft be seized somewhere? Is a complete teardown in order?

Any and all help appreciated as I don't want to sink any money into the item until I have some idea of the nature of this shift dificulty.

Thanks All.

The shift lever moves the shift rod up and down to move the dog on the prop shaft. You can see the respective parts in the on-line parts catalog here: http://www.marineengine.com/parts/johnson-evinrude-parts.php

To work freely it must be well lubricated. There is a grease fitting inside the housing.

It will help to turn the propeller or the flywheel if attempting to switch gears when the engine is not running.

Check the gear oil in the lower unit first. If thats OK, you will need to get some penetrating oil down through the shifter handle linkage. Don't put much pressure on that shifter handle, just a gentle wiggle as you put the penetrating oil to it.

Re: 1965 Sportwin 9.5 - Shifter issue.

Thanks for both replys.

Gear oil is good, linkage is free near the shifter, rod going from shifter linkage down into the housing not budging, can wiggle side to side, no up and down.

Where is the grease fitting in the housing? Are you referring to the one near the shifter linkage at the top by the handle shaft?

As I don't see it in the manual, how hard would this be to take apart completely (ie. remove housing to see what's going on)?

I haven't had the lower unit off, is there access from the bottom once the lower unit is off?

Thanks Again

Before anything else, remove the gearcase by removing the four screws and disconnecting the shift rod coupler. You will then be able to see if the problem is in the shifter or in the gearcase.

You mention the throttle linkage was seized up. Related to that is an interlock that prevents you from shifting out of gear at anything above shifting RPM...

Thanks all.

Is this interlock an internal thing? The throttle is now operating propoerly, but no change.

Will pull lower unit next. Fingers crossed and I'll post back with results.

Thanks.

Well...

Went to remove LU, surprise..... all four bolt heads broken off. No access to internals there, currently hoping impellor is not shot, any way to get at internals there through the propellor shaft housing ????

On a happier note a good soak with penetrating oil and a change of LU oil seems to have freed the shifter. Now moving freely.

So far throttle has been freed, shifter now working, tiller arm fixed, cleaning carb while awaiting arrival of coils, points and condensers . Praying everything in lower unit is OK as I can't even get a drill under the "fin" (whatever it's actually called) to drill out the old broken bolts.

If I can make it run, and the LU guts are good, I guess I'll just use it for as long as it lasts. If no impellor I'm out $60.00 in total but got 20 hours of enjoyment out of picking at it, seems like a good deal.

Re: 1965 Sportwin 9.5 - Shifter issue.

If all four bolts are broken off they you have a problem - there are only four holding the lower unit in place! The lower unit won't come off with the four bolts broken? Running it like that may loosen it up enough for you to lose the unit!

If you do get the unit off there's a good chance that the screws that hold the impeller housing in place are more likely to break, too, so some pre-heating and penetrating oil may facilitate things.

LU will not budge, currently upside down with oil soaking in again.

Perhaps if I get it running I'll run it in a bucket until is loosens up.

There is nothing holding the lower unit to the shoulders of your four broken screws except corrosion, so you can separate the unit from the midsection once you loosen the stubs.

Re: 1965 Sportwin 9.5 - Shifter issue.

Still no go breaking it loose. Wish now I had noticed the problem earlier (like before I took it home). My wife tells me I have a difficulty with getting obsessed with things like this old motor, so I'm trying hard not to end up throwing more time and effort into it than it's worth in the end.

I'll let it soak a while longer and then apply a little brute force and ignorance.

Try using a little heat on the housing where the bolts go through.

Got it apart, finally.

After endless cycles of heat and oil I had no joy. Then my parts showed up, replaced the coils and points, did the carb earlier . Mounted it in a bucket, half a dozen pulls and away it went. Ran it for a while, took it out , lo and behold the vibrations had worked the LU loose enough there was a small seam. Put an old knife in the seam, tapped it a few times on each side. Wiggle, wiggle, wiggle, pry , pry , pry and it came off. Ended up drilling out the old bolts as the use in salt water had them so corroded in place they seemed to be part of the aluminum. (no amount of heat, oil, tapping on them , extractors, etc would budge them). All back together now.

Now waiting for a calm day (a rarity here in Newfondland in the fall) to take it for a run and see what happens.

Thanks all for the help.
