Seagull parts diagram/ workshop manual?

[PetiteFleur]

I've had a couple in the past, the first many years ago, purchased from a local auction which was siezed. Took it home, removed the head and with a wooden block and hammer 'un-siezed' it. Worked well afterwards on my first 20' boat. Usually started after remembering to turn fuel on... The second was the later model with the later ignition - which was a basket case - worked perfectly when tested at home but as soon as fitted on the dinghy wouldn't start. They both always spilt petrol and messed up the car boot. Sold eventually and got a Honda 2hp which was excellent.

It will be fine. Just scrape out the gunk and refill with 140 oil. I think the gearbox was said to be happy running with a white emulsion of oil and water as the shaft seals are less than perfect. Any oil thinner than 140 will run straight out past the seals. We need a picture of it working on your dinghy.
Let me know if you need any gearbox parts as I have a spare lower unit (the top of the casting is cracked but the rest is usable)

There are no seals - just plain bronze bushes. Sealed gearboxes were the big 1979 development along with new clutched gearboxes.

She's alive!!

A bit of oil down the shaft and she would turn, a gentle clean of the points and we had sparks, a squirt of juice in the carb and she fires!

Will get the correct oil to mix up some new fuel, get a 25:1 needle, remove and repaint the shaft, give her a bit of a clean and she's good to go for another 52 years

Having had a 40 Plus and had great service from it and having some form fixing Seagulls for others I expected nothing less.

The original British Seagull outboards were made by the John Marston Company, the firm who made the pre war Sunbeam motorcycles.

John Marston Sunbeams were noted for the quality of their paint. The paint on the brass tanks of early Seagulls seems to last well too.

My one had to be started on full throttle when hot. Made it exiting on a narrow canal as it had no clutch...................................

While that is true the post war Seagulls owed nothing to the Marston ones other than a visual similarity. Quality of materials, construction and finish steadily declined over the years although functionally changed little until 1979 when the new transmissions and electronic ignition came in, followed later by the more modern QB series powerheads, although few of those were made.

If you could buy today , say new from a factory , would the exposed flywheel pass health and safety ?

I have never heard of anyone getting something caught in it though.

My last Seagull got stolen from a tender on a mooring. I had spent the whole winter tarting it up . Gold painted flywheel the lot.

Literally from the original "OPERATING INSTRUCTIONS" booklet got with the new motor in 1963: "... and avoid grease for the gearbox like the plague."

Think there was a case of a young girl whose hair caught and the others in the dinghy moved back to help, causing the boat to submerge and she drowned.

I don't know why one would go to all this trouble, spreaking as one who has seen a seagull run with no carburettor, just a fairy liquid bottle of petrol squirted in the port.
If it turns and has compression, and the fuel is staying, roughly, inside the prescribed areas where it should be, then a spin of the flywheel with an electric drill to rejuvenate the mag, and, uncle Robert!

The song what i wrote:

The Seagull Song.

(To the tune of the Good Ship Calabar, or any 8 beat tune)

(Finger firmly in ear)​

Come gather round you sailor men and listen to my song,

It's only several verses and I won't detain ye long,

Concerning of a fishing trip and our unhappy fate,

Out of Cadgwith in a boat I borrowed off me mate.


Our noble ship was GRP and fully twelve feet long,

And as we pushed out on the sea our hearts were full of song,

But it would be our downfall I was very soon to learn,

The bloody seagull outboard that was clamped upon the stern.


Now when I saw that Devil's work, me heart was damn near broke,

But I opened up the fuel tap and I applied the choke,

I gave the starter cord a pull, but was too rash I fear,

The knot in the end of the starter cord caught the missus round the ear.


Now she called me a couple of names as she moved up to the front,

One of them was idiot, the other one was.......-n't,

Twas then that she berated me with words exceeding cruel,

She said 'you are a bloody twat, you didn't check the fuel'.


I took the top from off the tank and then I peered inside,

And bugger me she was quite right, the tank it was bone dry,

A Seagull needs a mix of oil and fuel as we all know,

And one pint to the gall-eye-on, it was the ray-shy-oh.


I groped amongst the fishing gear strewed all about me feet,

Until a I found a can of petrol underneath the seat,

I looked round for a funnel, but I sadly drew a blank,

I splashed the petrol all about, and some went in the tank.


Twas then that I decided to check the ignish-eye-on.

I took the spark plug out and scraped the points until they shone,

I laid the plug upon the tank, and I attached the wire,

I pulled the cord, I saw a spark, and the whole damn thing caught fire.


I took my oilskin jacket off and I beat out the flames,

Then I attacked that en-gy-on with all me might and main,

I cursed it and I kicked it, pulled the cord as ne'er before,

Then all at once to my surprise it started with a roar.


I had let go the tiller, the throttle opened wide,

We shot round in a circle and I fell over the side,

The missus stopped the engine and she hooked me with the gaff,

I wasn't expecting sympathy, but she didn't need to laugh.


For sixty minutes or an hour we drifted tempest tossed,

And battered by enormous seas until all hope was lost,

Twas then through all the mist and spray we spied cape Man o' War,

We got the oars and rollocks out and pulled the boat for shore.


We hauled the boat up on the beach and we jumped in the car

Roared off to Robin Curnow's shop, to buy a Yamaha,

Come all you jolly say-lie-ors, who'd sail the seven seas,

Don't have a Seagull outboard boys--get one that's Japanese.

Brilliant!

An old gentleman here was mackerel fishing and the line went in the flywheel, he threw himself flat in the bottom of the boat as a 2lb lead whirled overhead.
