Saving Old Seagulls

The engine number is clearly wrong.

The SJM was never in any way, made as a longshaft.

I suspect the number and date would be correct if you ignored the 'L5'

That makes it 1956 to 1957.

That is the real age of this engine I am certain. the L5? anyones guess, certainly not a Seagull date!

Hope this clarifies matters,

Hi Folks

Thanks for a great piece of informative technology.
It gave me all the data within seconds, now I can get spares etc knowing exactly what engine I have.

Hello all
I have a century CPCR 5485, also unable to identify 1731JJ6.
When I enter the numbers, all that comes up is "incorrect model number".
Any ideas why ?

I think you'll find that Seagull ceased production of CPC's in 1963 & yours has a date of manufacture that reads October 1976, hence the confusion.

The 'R' in the engine number keep cropping up. It is not supposed to be used in the date code, but is also seems to be, but only as an indication the motor went back for reconditioning, or in later QB models, to denote Roller bearing crank.

However we are finding lots of instances of obviously later motors with incorrect engine coding and the additional 'R'.

Maybe some one out there night know, but sadly there are not many left from Seagull factory days who can answer.

I have heard tales of models being built for export with odd codes and when the batch was sent away a few 'extras' sold at the factory gates.. seen a few of these...

We see 1984 model 102's with electronic ignitions and conversley FPs in the 80's with Wipac MkII points ignitions...

Think there are always going to be anomalies with the information Seagull passed to me, even without owners or repairers giving them their own interpretation of a 'suitable' number....

Sorry this is as good as it gets folks, unless you know otherwise of course.

Your SD has this 'L3' business in common with quite a few of those I have registered. Some have 'L4' and one has 'L2'. I have one with 'P3' in the workshop. You may find all manner of other codes on the other side of the crankcase - this has only appeared on SD motors, and is most probably some sort of reference for the military, who do so love their stores numbers and issue numbers and the like.

Nobody who worked for Seagull during the war has cropped up yet; hardly surprising really. There weren't that many staff then, much of the work was farmed out to local businesses. The factory as such was mothballed early in the war, only to open up again after the first orders from 'the Ministry'. The only man from those days cropped up last year at Ibsley. He started as a youngster in 1945 drilling bronze castings for brackets; he was astonished at the sight of a 1946 Model 'D' which he must have worked on as he was the only man employed to perform that task. The SD motors were still being produced in 1945, but he never saw the complete ones.

They only made motors for the military from '42 to '46, a couple of thousand were SN models,so yours has to be in the middle somewhere which dates it to 43 or 44. Disregard the L3 bit.

Charles, I imagine your supposition is correct.

I was Army for 14 years and all kit had a military reference number. They almost always started with G, as in G1098 watch, the standard issue military wrist watch; or L, as in L1A1 rifle. My understanding has always been that G stood for General whilst L stood for Land - as in Army. I don't know if the Navy had S for Sea or the RAF A for Air!

I've just re-joined the ranks of Seagullers (?) after 40 odd years. Purchased a 102 to replace the Evinrude 6hp anchor.
Delighted to confirm the seller's description of the motor (perhaps he used your chart?) Happy boating to all in 2010.

Here we go; Charles posted this last May:

"At any rate it is a circle with the arrow mark and 'CIESS' which stands for 'Chief Inspector Engineering Stores and Supplies' and it indicates it has been accepted into British Military Service. It is always stamped on the skeg, invariably it's a 102"

Because the far East was a prime destination. First objective was Burma, lots of rivers to cross, very few bridges.

Lots ended up in Austrralia after the war, surplus materials were 'got rid of' locally to save the cost of taking them home. I'm sure if you check out post war boating magazine adverts you'll find SDs for sale, some unused
