Saving Old Seagulls

Isn't the periscope there for the Helmsman to see where he's going?

Won't you need a snorkel on the carb?

Nice work! That will generate a few smiles.

I've been approached by a collector who's researching the production history of Mallard outboard motors, He asked me if I could help him by giving him the serial numbers from my Mallards so he could try to understand the total production numbers & years of the 38cc 1 hp model. To help I'm asking...

Oh no he wouldn't !!

Too heavy!

Never weld crankcases without having both halves bolted together, helps prevents distortion. Reassemble the crank & the 2 crankcase halves, oil the main bearings, check they mate properly, very small gaps can be sealed using RTV silicon as a gasket paste & rotate the crank to ensure it rotat...

1/4 BSF, somewhere on here is a post containing all the thread sizes.

Leaking oil or grease are a symptom of worn bearings or prop shaft.

Doesn't seem to work when I try, is it me?

Rubber water pump impeller so back pressure shouldn't be a problem.

Have you checked the water delivery tube between the powerhead & the cylinder?

No comparison figures in that tech report only push in newtons!

You can't help wondering why they didn't try a height adjusting bracket for the long shaft Kingfisher, if they could measure a short shaft Kingfisher without major problems?

Doesn't 10% more firing strokes, imply your putting 10% more power into the water that's used to propel your boat forward? (How much push your getting on the back of your boat). As measuring the power output at less than maximum revs in it's normal working environment, would give you a lower inaccur...

Measure the revs at full throttle of a static bollard & full throttle in open water.

You'll find your getting more revs going free, more revs means more power strokes = higher push!

Yes Seagull did, but not a static bollard pull, they had in the late 1980's a transom bracket with a set of scales built into it, so they could measure the thrust at the higher revs when under way. Which was higher than the static bollard pull & more representative of the results that a customer...
