Saving Old Seagulls

That engine look ok, new cylinder and you will be sorted.

If the gearbox had some oil in it then it should be OK.

The ones with just dust in can be more of a worry.

You will soon have it running.

H-A

Does the gearbox turn ok?...if no fill it full of diesel and let it soak....

I'd bet that the gearbox is ok on this motor-the fact that ANY oil was present is a good sign-the Seagull box can take serious abuse and still polish up well-I've
opened gearboxes dry as a bone and rusted solid with no smell of oil and with tlc all worked out.Serious heat alternating with immersion in diesel has worked for me.I guarantee that by this time next month you'll have two more 'Parts' motors that you probably won't want to cannabilise either-addiction is a shocking thing! good luck with it!

I remember finding my fist Seagull in a skip...happy days
seized solid but it sparked an interest

Also what ever you do don't put in an advert "wanted seagulls"..or your stuffed like the rest of us!

Hello again,

Going to try and get the gearbox apart later on today hopefully. It turns fine so there's hope there.

I'm not sure what to make of the whole discussion about

But if pouring money into trash is more fun then pouring money into utility have at her.

I picked up the engine for virtually nothing and am quite happy to spend a bit of cash getting it back to working order and looking something like it originally did.

Where's the fun in getting something that already works and looks fine?

I'm a marine engineer by trade so most days im working on anything from 4hp outboards to V8 inboards. This is just a small project, not for monetary gain and to be honest I haven't even got a boat lined up for it. Its nice to have something that is basic mech engineering rather than having to test cdi units and a million electrical connections to diagnose a simple sensor fault.

Anyway, keep the advice coming, it's all good. I will post some photos of the gearbox later.

Cheers,
Dan.

I'm the same as you, I like stripping rusty old things down, and restoring them back to what they once were.

Lets see plenty of pictures as you progress this engine. We like pictures

So long as it turns you don't have to strip it..put some heavy 140 grade oil init and it will probably be fine

these things don't come apart easy so if it aint broke I personaly don't fix it as it can make more problems

of course you may want to strip it for the pleasure of doing so.

My favourite rebuilds almost always started as a seized, no hope sort of project, I guess that is where the satisfaction is.

A word of warning, Beware if you place a "wanted seagull outboard" advert and you are the sort of person that cannot say No, I did last year........nearly upto 90 at the last count! The wife is going Nuts and the phone still rings from time to time a year later

All good fun though

Got the Gearbox open, There was plenty of oil but quite a lot of sand also which made it a nice paste like substance but all was still turning freely. To be fair, I have opened up worse looking gearboxes on engines less than 12 months old. Having trouble getting the prop off but ran out of gas in the torch so that will have to wait. The only screw i'm having trouble with is the hidden/sunken one which holds the exhaust outlet/gearbox together but that is now soaking and i will look at that with some heat tomorrow hopefully.
Right, off to drink ale at the Lugger Regatta, might ask around to see if there are any seagulls lying in peoples sheds! haha.

Oh dear

to see if there are any seagulls lying in peoples sheds

There are.

Lets be honest, apart from a select few, most people don't care a monkeys about these motors hence you can pick one up for less than the price of a hair drier, and it does not have to be a particularly good hair drier

By what your saying about grit in the gearbox, That sounds normal for a well overdue oil change. Once you pull it apart and clean everything, it should be all good. If you dont have a gasket for the cover just use a bit of gasket goo to assemble it. Ive done it to a couple of my gearboxes and it actually reduces the clearance by 10thou (The gasket thickness) and meshess evrything spot on. And if you have a bench grinder wire wheel, just buff everything up instead of painting it. Ive also had a look at your pics while my photo was uploading. The piston--rod--crank and cases look fine. I am probably going to have a couple of poeple chip me here, But i would just clean up the piston on the wire wheel and use the piston rings thats on there now. Ive used a set of rings on my Tc-102 that had almost a 1mm ring end gap but still got a good 55psi of compression. Give your new 40 plus cyl a hone and coat of black b4 you fit it onto the crank cases. You can use gasket goo again if you dont have a base gasket either. This is your 1st seagull remember, and one thing i can tell you is they are very crude-rugged-simple and totally crazy little motors. Make sure you have plenty of oil drain pans when your finished using your seagull for the day. Oil leaks out the brass bushes on the prop shaft. They dont have any oil seals. Just bushes.

They are more expensive up here id say...sometimes surprising what people want for these things maybe they are behind the times on your Island...your very lucky mate!
