Re: A question of Horse Power

Rex NZ - thanks for the pics - useful - now I 'get it' !

Manifold - the target is a boat similar to a Drascombe Lugger: a displacement hull, so a big, slow prop is what I'm working towards.

Re: A question of Horse Power

I think if I was given the choice between a BS & a B & S powered outboard to use to cross the Atlantic I would get further but slower with a classic Seagull! Ah - don't misunderstand me Charles - I've got more Seagulls that I care to admit to, and I've no intention of selling 'em or modifyi...

Re: A question of Horse Power

Thanks for the replies - this sort of thing is obviously of interest to the mavericks amongst us .... The underlying reasons behind this project are: a) seems that there aren't any 'sensible' outboards out there any more - meaning low-geared with BIG props. b) B&S engines are 4-stroke and econom...

A question of Horse Power

John makes some very sound comments regarding Seagull horsepower on his site, and I recently came across a Villiers document which states that their 98cc Mk10 Stationery Engine is rated at 1 HP @ 2,000 rpm and 1.3HP @ 3,000 rpm. The reason I'm writing about this is that I'm just getting around to ac...

102 tiller wing nut thread

On the 102 AC and similar models there's a wing nut which varies tension on the tiller arm, by courtesy of a rubber insert inside the tiller arm lug's conical bore. For now, I've replaced the wing nut with 2 x plain nuts from the junk box, as the original wing nut had it's wings busted off. I'd like...

Re: Another 102 lives ....

The water inlet block mounted on the side of the exhaust tube on a 102 serves a dual purpose. The first is to inject water into the exhaust to cool & quieten the exhaust gases. The second to act as a tell tale & a pressure relief hole. Both of which are fairly important functions, not somet...

Another 102 lives ....

Bought a 1946-7 102 last year in a farm 'closing down' sale - looks like it had spent the last 10-20 years in a barn collecting dirt and bird poo. You may be able to guess the rest: cleaned the points, cleaned the carb bowl (some gunge) and filter (was completely blocked), checked the tank fuel filt...

Re: Drive shaft tubes

Porters in Wisbech had some useful tube a while back, although a little bigger than you want. I bought only a foot of the stuff to make some adapters with. It's 33.4mm OD, and has a 3mm wall thickness. I believe it to be 316. Stainless at the time was £1/kg. It might be worth checking their yard to...

Re: Phosphoric Acid

In my SCUBA diving days, we used to use Citric Acid (ex brewing supplies shops) to remove marine concretion from recovered artifacts. I still use it to clean furred kettles. Tablespoonful to a pint. Welsh water will also clean furred kettles if you're not in a rush - so regular flushing of the engin...

Cost of a set of points ?

I was looking for a Mariner impellor on Ebay earlier this evening, and stumbled across a bloke selling outboard spares, including those for Seagulls. So I had a quick looksee at the Seagull bits, just in case he had something of interest. Now maybe I'm out of touch with prices, but £40 (+ p&p) f...

Cheap 140

If anyone's in the Wisbech area - EP140 can be bought from Boston Crop Sprayers (next to the marina, opposite ASDA) at £8 for 5 litres.

They also offered to source SAE250 if there's enough demand.

Interesting. What's the state of the aluminium castings ? Graphite and copper are a long way from ally on the electrochemical scale so serious galvanic corrosion should be expected. If not, I wonder why not ?

Certainly copper-bearing anti-seize should *never* be used on ally marine engines.
