Elgin 3.5 hp year?

[Buccaneer]

My uncle gave me an Elgin outboard today, I’m guessing circa 1960 ish.
Only numbers legible on the transom mount tag is 0 3928.
On the power head, stamped, is 636 0031 0 3928.

I’m having a hard time finding any information on it.
Was it made by West Bend, or McCollough?

Also wondering if anyone has a part manual for it?
It appears to have good compression, and even spark.
I don’t think it’s been run in many years though.

Also curious what it has for a water pump, and if available.
Thanks!

It is a Scott-McCulloch. Very good runners.

Thanks Frank. I spent an hour this morning cleaning it up, and just
popped open the gear case before I came in for lunch.
Have not pulled the gear case off yet to look for a waterpump.

I pulled the gear case off today to inspect the water pump.
Other than being very greasy, it was still in good “fit” and shape.
Just for kicks l dug around to see if I had an old Gale 5 hp wobbler
pump. I found a NOS wobbler, but I have no idea where I got
it, or if it was for a Gale 5 hp, but it fits in the Elgin perfect.

Any idea if Gale wobblers could be the same?
Photo with measurements……

I blew compressed air up the pump discharge to power head. I heard
air moving, but it seemed like there was a fair amount of back pressure.
Hopefully I don’t have pluggage (the motor that is!), but I’ll try tomorrow to
throw the motor in a bucket of water and spin the driveshaft
to test the pump.

I’d be very surprised if the Gale and Scott wobblers are the same. Let us know.

I may have to tear apart a Gale to find out.
If someone has one laying around, I have the dimensions of the Scott one in the photo above.

I tested the water pump this morning in a bucket of water, spinning the power head
over with a drill, and got “nothing”.
I felt certain that the wobbler was good enough to pump water, and seeing how
I had more back pressure than I thought normal, while blowing air up the discharge tube yesterday,
I pulled the power head off. The outlet in the power head was plugged, as was the mating
tell – tale spigot on the lower unit.
I rodded out the holes, but found it impossible to blow compressed air thru the water
jackets, so I made up a little wood fixture to bolt on the outlet, so I could blow air
through the water jackets. Got a little bit of grit out, but not too bad.
I was going to take the head off, but it didn’t want to let go, and I didn’t want to
ruin the head gasket, so I abandoned that idea.

My drill is a 1500 rpm unit. I’m sure this motor will pump enough water at speed,
but I’m wondering about at idle. The top of the power head is about 4″ above the
lower unit motor mount flange, but with the drill less that full speed, it’s only
pumping water a couple of inches high.
At idle will the wobbler pump force water up to the top of the power head, regardless?

Well sure, that motor should be able to idle dead slow. Like 500 RPM. And cool just fine at that speed.

[Buccaneer]

I put the powerhead back on the lower unit, and tested it again.
I was worried at first that it wasn’t pumping at all, but I suppose
it took a bit to fill up the water jacket, then all looked well.

Prepare to be boarded!
