In the small port remove the bottom screw/bolt to allow the gearcase to drop down.

The other port you are referring to is the water intake when going in reverse, not much in there, just ensure it is free of debris.

Re: Having some trouble with an old motor.... when i say some.....

Just a update to my progress and a few photos of the cowl aswell to help with the identification (I would Ignore the Johnson label as there only stickers and could have being put on at any time)

I managed to remove the lower lower leg unit today after some problems it freed up. Inside the metalwork is perfect and there is no sign of corrosion anywhere on the motor at all. Excellent news. I'm just having a little problem removing the powerhead ive removed a couple of the bigger blots that were holding in the powerhead (2 rear bolts). But there seems to be several smaller bolts holding the powerhead in place as-well(See photo). I say that I presume they hold the powerhead in-place and im not missing something else all together. They seem to be a strange size however there not 7mm and there not 8mm it appears to be about 7.75mm (see photo) and that got me thinking if it is an imperial bolt but that wouldn't make any sense as all the other bolts ive taken out were metric...... :S

Thank you all for your help so far, I'm hoping to make a restoration thread after ive finished with it so people can see how I got on. I find myself needing a parts manual and drawing more and more now so if anyone could come up with a deffinate model from the serial number C(0or8)430802 it would make my job much easier. Its strange how I thought this would be annoying project yet I find myself enjoying it more and more. These Old outboards were built to last! its still solid!

Thanks for your continuing help

The First Picture Is of the base the bolts of strange size I was talking about are the small ones dotted about im talking seriously small but theres about 6 of them, the Second picture is the reading i get when i measure the bolt head and the rest are of the cowl

Most fasteners on these motors seem to be 7/16" or 1/2", my 2 most used wrenches working on OMCs.

I am having a nightmare! the bolts are about 7.75mm and there smaller than 5/16" . I reli dont understand imperial system AT ALL so I don't know what size spanner to go buy the 5/16" nearly fits i think one size smaller would be the key... I have a full set of metric. I cant even read the calipers in the imperial scale so abit of help would go along way . Also can anyone help with the the model I.D. for a drawing and parts now the pictures of the cowl are up

Many thanks

Re: Having some trouble with an old motor.... when i say some.....

I wonder if the M stands for Montgomery Ward?

I am pretty sure he M is actually an M inside of an O, for Outboard Marine. It's found on many castings...

Re: Having some trouble with an old motor.... when i say some.....

As noted above - get a 5/16, 3/8, 7/16 and 1/2 inch wrench to handle most jobs on these old OMCs. The flywheel nut will be 3/4. Some metrics are very close to Imperials, .ie the 11mm and 7/16 are close enough for most applications.

If that's the case does that put the whole model and make in question again or do you also agree that it's a 6? Gale motor?? As for the imperial spanner what should I be using to get thoose small bolts off if 5/16th is too big its like a size down from that.....?

Re: Having some trouble with an old motor.... when i say some.....

Might be 11/32. Never found one on an OMC - maybe someone previously made some shade-tree modifications and used what they had handy.

No, the OMC logo doesn't change a thing - it was on all their castings, be it Johnson, Evinrude, Gale, etc.

Here's an ad for the Gale 15 from 1960. It was pretty much unchanged from 1960 to 1963, aside from maybe some color changes.

That's the baby looks exactly the same as mine rite down to the choke and needle positions did the parts change between 60 n. 63 or can i just get a parts / drawings for any of the 15's?
Still can't get thoose bolts out can't figure the size I measured it with calipers the pic is attached at the bottom of the last page

Re: Having some trouble with an old motor.... when i say some.....

Sure looks like 5/16 to me on the calipers. Are you using a 12pt or 6pt socket? If the bolts are old & crusty, they may have rounded corners and a 6-point might help things along...

I don't think they changed much of anything on the Gale 15s during that run. In fact, the Gale 15 was basically a restyled version of the old Johnrude 15hp from 1956....

Subscribed to this thread. Interesting to see someone on the other side of the pond revive one of these gems.

Meng,

Found a chart on-line that may give you some help with understanding fractional S.A.E./Imperial spanner sizes;

Re: Having some trouble with an old motor.... when i say some.....

I am having a massive nightmare with these bolts! , Ive managed by the skin of my teeth to remove one by using PTFE tape to thicken it up and using a 7mm socket and a hammer and the biggest torque wrench I have. The others will not budge with either 7mm 8mm or 5/16th it just too small for the ammount of force that is required to remove it. CAN ANYONE THINK OF ANY WAY TO REMOVE IT im getting desperate now. Ive tried shaking it loose with a air chisel, cleaned it up with a wire brush, blow torched it..... its just not moving and some are 2 of them are so close to the leg that I cant get a socket in and around the bolt! I would normally at this stage drill it and retap but I cant get in with a drill! can anyone make my week and figure a way out. ANY suggestions welcome no matter how silly they seem!

THANKYOU

If you can get in there with a Dremel, cut the heads off. I had to do that with a friend's boat when he bought it from down on Long Island (salt water). We cut the heads, pulled the powerhead, and then had more meat on the shank to grab with Vice-Grips...

If i cut the heads off is it not still threaded into the powerhead and the thread in the metal? If it comes out with taking the heads off Ill do that and get it over with! the smile on my face if i manage to finally get the powerhead off!

Re: Having some trouble with an old motor.... when i say some.....

Just so everyone can see here is a picture of 2 of the remaning 4 bolts so you can see how close they are to the legs.

Had enough of messing around now. Going to take the dremel to it tmorrow and see what happens. Theres anouther screw stuck in on the bottom and I cant get enough force in with the - negative screwdriver might have to drill that. Im thinking of painting it in the original colours to get it back to how it used to be any thoughts ?

Re: Having some trouble with an old motor.... when i say some.....

I would imagine all the nuts and bolts on johnnyrudes and gales are what is referred to in England as AF (American fine) called SAE over here.I don't know of any that used metric bolts or even do now.They are very resistant to change in America(110 volt electrics).!/2 inch corresponds to 13 mm 7/16 =11mm.As has been said,those sizes should cover most of them,with one or two 9/16 (15 mm).I am currently going throgh my info pages to see if I can identify your model but don't hold your breath.Are you sure that's the only core plug on the motor?.
