Saving Old Seagulls

Just having a look on Google earth to try & work out where your located, can't see anything on the bottom.

Not too impressed with your other boat parked on the other side!

Big end caps are marked so they shouldn't be reassembled with the cap the wrong way round, that's the most common cause of fractures.

I don't think they sell 18 x 1.5 mm grease nipples in the UK, lucky you, we have to make our own!

Mk 2 flywheels are quite brittle so handle with care. Did you try to start by using the electric drill silly idea? as that can over tighten the flywheel nut! I've locked flywheels by putting the piston just after TDC, then filling the cylinder with fuel mix & replace the spark plug, a sharp tap ...

I've always been intrigued by the Olympic, only ever seen one & that was in NZ, but I wasn't allowed to take it to bits to see how much is owed to Seagull.

Has anyone ever done a CSI investigation on one, to see if any of the components were made by British Seagull.

You might be being a little bit harsh, as that appears to be a Seagull made replacement SD crankcase. Which would you prefer original crankcase with tired main bearings or a replacement that probably has done much less work? Your right Tam, I've had bits from him, accurately described, & no prob...

I was 16 at the time, my previous car was a 46 Hilman Minx that seized up as I was running a mix of central heating oil plus petrol I syphoned from dads car.

Seagull hardened steel thrust washers come in 3 thicknesses 12 (0.104"), 13 (0.092") & 14 gauge (0.080"). And are used both between the pinion bearing & the pinion gear, & the crown wheel & the bearing in the end cap, in varying combinations to give a suitable gear mes...

If you look on that site you will see one of the cars I owned in the 60's. A Berkeley T60, looked like a baby E type, mine had a 3 cylinder 2-stroke, chain drive, dynastart Anzani, that I wrecked a rod on before I got it going properly .

Anzani models included:- Minor (1/2 & 3/4hp), Pilot (1 1/2, 2 1/2 & 3hp), Seamaid (3hp), Jet (3hp), Super Single (4 & 5hp), Seasprite (7 & 15hp), Sports Twin (14hp), Unitwin (10 & 15hp), Supertwin (15hp), Startwin (18hp), Magnatwin (18hp), 65 (6.5hp), 180 (18hp), 400 (40hp), Flee...

Similar to nylon or acetyl, machines well & very slippery.

A length of turned Delrin with a decent groove in the middle, would be ideal. Seagull didn't help by putting the parallel face on the outside, it will mean you can't tighten the retaining bolt very tight without loading the casting up. That's what I used when I re-manufactured the FV series thrust b...

There is a great deal of merit in Hugz's suggestion, a square bit of hard wood with a bit of a groove in the middle & an 8mm hole offset from the centre & you could end up with a 4 thickness thrust block adjustable by rotation held in position with a much cheaper 8mm stainless nylock nut &am...

Dave take the thrust bock assembly from your existing 102 cc size transom bracket, & try it for size in your new one.

It's difficult to be certain from the pictures, which block you require Century or QB for your new bolt on bracket.

Have a look at your last flywheel picture at 6 O'clock on the baseplate, you will see the letters "JM" underneath that spoke of the flywheel you should find the rest of the number that Hugo wants.
