Saving Old Seagulls

It is obviously a Seagull, the fuel tank is instantly recognisable, but what model is it? (click the pic to enlarge)

It looks like a Seagull fuel tank, but is that fuel cap bayonet fitting?
We really need to see the motor to give a definative answer, I see no sign of a cooling system is it air cooled?
I bet it could be a seagull like tank on an aircooled motor that's never been to Poole in it's life.

I did not undo the cap but I noticed it was a metal one. I suppose you are going to tell me it is something rare that has to be rescued.

We think it was used to provide the power for this conversion.

Your not making this easy Vic!
The paint on that leg "almost" looks 5R blue, but it's different, wrong sort of tiller arm mounting.
The crankcase in the first picture bears no resemblence to any seagull one I've seen & I have examples of almost every Seagull ever made from 1932 to 94 except an FV & the little model 40 & it isn't one of those.

Definately not a Seagull engine , it's four stroke for a start , I'm inclined to think along the lines of a Kohler , difficult to say from that pic. If you could show us the other side of the engine , I'm fairly confident I could identify it.
That outboard leg looks decidedly Japanese to me.

Hi all,its a 4 hp suzuki leg probably had the powerhead discarded due to siezed roller bearings,a common problem with this model!

Seagull never used a Suzuki leg only a Yamaha 4B one on the 5R.
None of the Seagulls with the covered engines 170, 125 & the Seagull Sport range ever used this type of leg.
The 5R had no cover over the powerhead & apart from the leg & the modified Crankshaft & crankcase was a Kingfisher powerhead painted metallic sky blue.

Looks like a yamaha leg to me,posilbly a "bitsa" although seabee used yamaha legs later on

Sorry to say Paul that definitely not the type of Yamaha leg that Seagull used, the tiller arm is mounted in the adapter plate on the 5R & in the lower half of the engine cover on the Yamaha 4B the leg came from.
If my camera had not been squashed by airport baggage handlers I would take some pics to illustrate.

I only posted the pictures as a joke. But next time I go to the yard I'll have a look to see if there is any id on the leg or on the engine in the first pic

O.K. Vic. What you have in the first pic is an inboard seagull with an electric power take-off. This would generate the elecricity to power the updated version of the "Green-Gull" in the second picture. The addition of a battery charger would give the Gull a "stealth" factor (apparently as specified by the SBS). This meant that the boat could run on the engine on approaching enemy beaches and then change to battery power, for silent running.... River Patrols...Half a dozen men, armed to the teeth, gliding silently up the river...Could play havoc with the enemy!!!

Thanks upthecreek for that explanation. I am sure I can find someone who will believe it but too many more like that and we'll all be up the creek.

For those who were interested in the "Seagull" engine here is another pic from the other side.
