Saving Old Seagulls

They are a 1970s accessory, not made by seagull. It's called a "Rotogull" They do have a tendency to seize up I've heard.

That's a really interesting find, not many of those BMB inboards about. I have an outboard version similar to that, which I bought for spares, but is actually complete, still in its box.
I'd agree its worth cleaning out the water jacket, the cylinders are a weak spot for corrosion.

There are quite few little differences in decals over the years, here are the ones John sells at SOS.

Tiffany the prop masseuse?

Like the way you have preserved the tank. I was thinking of doing the same with my very original HSD. Just giving the tank a wash and a couple of thin coats of lacquer.
Nice original engine.

The two brackets you have are basically the same however it should not be painted.

Don't put grease in the lower unit, it will result in little or no lubrication to the gears and pinion bush. If you put 140 grade oil in and fill it to just below the level of the prop shaft it will be fine.

Looks like everybody had an excellent time

Cant beat a bit of seagull power Happy christmas to everybody, and lets see some more seagull projects on the go in the new year!

Nice job! Next you should find a nice 102 or little 40 to work on

5/16 BSF, if I recall.

Another option is to take a thinner gear oil such as 90 grade and mix in some general purpose grease in to thicken it a bit.

If you look around you will find in the US for sure. These parts are often common sizes used in different applications. You can even make your own from thick gasket material.

If you are in the US, try any classic motorcycle dealers, or even look on ebay. Don't overtighten the banjo bolt, the threads in the carb body can easily strip out.
