Help ID this Seagull

[thepetrolist]

Yesterday I bought this Seagull without knowing what model it is. The seller knew nothing about it and I haven't seen it in person. I found it 450km from my town so I sent my brother to pick it up since he lives in the same town as the seller.
I tried to get my brother to take a pic of the serial number but after several times of asking and not getting it I'll turn to you guys. He doesn't care too much about old engines so I shouldn't blame him. These two mobile pics are the only ones I got from him.

Any ideas of the model and possible year?
I'm thinking 102 but I'm not sure. The lower unit is missing in the pic but I got it in the deal.

Cheers!

Hi that looks like a good project. Yes 102.

It looks like an AC / TC is there an R in the engine number stamped on
the lower crankase half?

As It looks like it has been upgraded in the past, or had more modern additions during a refurbishment.
H-A

P.S. also it looks a bit short in the leg, may be cut down.

From those very grainy looking pictures it looks pretty spot on to me.
What you have there is indeed a model 102. (possibly in the 10,000 to 30,000 serial number range)
Looks to be an AC (or what's left of it) probably a later model but definitely pre 1955/6 going by the slotted core plugs in the cylinder.
Also it looks like a standard shaft model, so nothing to worry about there.
Transom mount looks good and correct for the time period.
Tank mounting straps look to be correct also for this time period as is the fuel cap.
Throttle lever is correct.

Hopefully the gearbox that was part of the deal will have 3 sets of 3 holes in the water inlet, NO OIL NIPPLES, and be a clutched type? (i'm still trying to work out which is the correct prop)
If so, you have just about everything you need to put this "golden oldie" back together.
What's going on with the carb though? Is it broken or has it been taken apart?

Still a good basis for a restoration i think despite what it looks like at the moment.
Quite a nice find really, well done.

Thanks guys! I'll try once again today to ge hold of the serial number..

The engine is complete, it has just been partially disassembled thirty years ago before it was put into storage. Don't know why?
Only thing that is missing is obviously the starter rope.

The prop is a four blade if that helps.

[Collector Inspector]

Yeh

If gearbox has holes then a Bowtie Prop?

Would be clutch as well and as above no nipples.

Gearbox plug should be brass.

Then again a four blade was the replacement at a later date. Easy fix as lots of Bowties around.

Good work in finding this aye.

Another thought on props for this motor, might have been a 4 bladed cloverleaf. (still working on this)
The square edged hydrofan type was a much later type, but by my reckonings either a "bowtie" (2 blade) or a "cloverleaf" (4 blade) would look good on this.

Keep us updated with any progress on this.
I'm particularly keen to get the data on this.

We ALL LIKE PICS, so more pics please.

Seems like I got your attention now, eh?

I'll post more pics when Inget them. Still haven't heard anything about the serial number.. Man I'm getting annoyed. I haven't seen this engine live yet and god knows when I will.. I'm dying to get some more pics! I will keep you updated.

[headdownarseup]

just to whet your appetite, here's my slightly older AC doing what it's supposed to do. (take a closer look at the core plugs in the cylinder and then compare it to yours)
enjoy

I don't like the look of bowties ...now SD props ...now your talkin

[headdownarseup]

There's a lot of confusion with some of these older 102's (so it seems) but slowly i'm starting to make sense of it all.
The AC in the pics above has an SD style prop (i like 'em too, especially when they're polished up)

In fairness to the "bowtie" prop, despite how it looks, it's not that bad at pushing a boat through water.

Yes it would be most interesting to see pics of all the different props seagull made would it not?

Here are three from different generations of 40's 1951, 1955 and 1976

We've been discussing this in the background for several years now, a plan picture of a prop doesn't really give enough information, for comparison.
So the suggestion was that a half a target with a clock face superimposed, printed on a sheet of A4, 2 of which could be pasted on to a piece of ply with a 1/2" dowel projecting from the middle like a sundial.

The correct style target would give would give the diameter & the clock face the approximate blade widths & shape, the hope was that someone would design the targets that would print out all the same size from everyone's printer, so that all prop reference / identification pictures would be of a standard format, so easily comparable from which a reference database of all Seagull props could be compiled.

2 slightly overlapping sheets of A4 paper would cover all the known Seagull props from the little model 40 to the 102+ bargepusher.

The stumbling block was finding a drawing format that would printout to the correct size from everyone's printer.

The complete database could consist of 30 ish propellers!

[Sandro_Picchio]

Hi,
if anyone has access to Autocad drawing program, the target and clock face drawing can be printed very accurately at 1:1 scale.
As the A4 sheet is not large enough, by adding to the single drawing a mark line, two areas can be printed on two A4 sheets and these can be joined superposing the mark line of both.

How can the pitch of the different propellers be measured and compared?

Sandro do you have AutoCAD & can you use it to design the target?

Don't you need AutoCAD or a similar cad program to enable your printer to print a DWG file to an exact size?

It would be a lot easier if members could just download a file & print out a target that would exactly match the background in the database pictures, without have to reduce or enlarge the picture until it is nearly right.

This would be a 10 minute job for a CAD draftsman, then we would need a database specialist so that it could be indexed on engine number, number of blades, style, etc.
