Gold Cheetah Outboard
« on: 06 October, 2015, 03:50:18 pm »
As promised in the New members Café, here is a thread on the Gold Cheetah outboard. Better late than never aye!

The Gold Cheetah outboard was produced by the Boundy Manufacturing Co. Pty. Ltd. in Springvale, Victoria from approx 1954 through to 1960, along-side the Lawn Cub, Lawn Scout and Lawn Patrol mowers. As a side, Boundy Manufacturing were also known as Boundy Industries.


At one stage all Boundy mowers and outboards shared the same 3.6hp engine, which was quite unique ie when compared to other air-cooled mower engines of that era. For example, the engine did not have a traditional style flywheel/magneto atop, rather it had magnets within an aluminium housing attached to the crank. As the crank rotated, the magnets passed by an ignition box comprising coil, points set and condenser, all mounted to the front end of the crank case.


The original name for the Boundy engine was in fact “Gold Cheetah”. In its later years, it became known as the BMS series 10. From inception however, the Gold Cheetah name was also applied to the outboard and stayed with that until the business ceased to operate around 1960.


The Gold Cheetah outboard featured below, is the third in my collection. It was purchased from a one owner family in December 2014 within a few km’s from home. The following few pics are from the eBay ad and as collected.





To say there was lots of rust and corrosion under the paint. Would be an understatement Take note of how much fell away just through handling and being left in the breeze a few days.

Whilst nice, decals add complication to any resto as they too have to be reproduced. Needless to say, it pays to take as many pics and measurements as possible.



A long weekend with nice weather, nothing better to do and missus away made it possible to progress the restoration o this one very quickly.
Restoration of this one moved along very quickly.
Day 1. Disassemble, strip old paint, remove rust & corrosion, clean parts, fill dents, remake all gaskets.

Day 2. Sand filler and spot fill, prime all parts to be painted, clean & polish other parts, decarbonize piton & rings, clean (light hone) bore, clean crank case and lubricate, apply top coats, apply clear coat.

Day 3. Finish rebuilding carb and throttle, finish cleaning and polishing unpainted parts & reassemble.

With the above-mentioned out of the way, it was time to finish the cowl, fuel tank and recoil starter and begin recreating the decal.

The cowl was very rusty and needed a truck load of work. The tank (which is welded to the cowl) was in pretty good shape with only a few small dents on either end. The decal took at full day to reproduce using MS Powerpoint and then exported as a jpg file. It was then just a matter of finding someone who could print on to Gold vinyl. Note: Image is black on clear. Gold as seen  in the image below was added just to give an idea of what the finished item may look like.



I decided the recoil starter housing needed some ‘special’ attention. Normally everything is just painted over, but I felt leaving the raised text and cheetah graphic raw, it would look better.





Decals arrived approx a week later than expected. That gave me a heap of time to remake the throttle cable, further polish all the brass and add some detail.

Forgot to mention earlier in the thread, based on the various parts and components used on this Cheetah, I estimate it will have been manufactured sometime between 1958 and 1960. There are some subtle and some significant differences between this one and the earlier models.

Very nice restoration job.

Was this the same as the Golden Cheetah? I had one years ago, but don't remember the details to identify it positively from the photos, though it was similar. There was an earlier thread which referred to the Golden Cheetah engines here:

http://forums.tomm.com.au/index.php/topic,317.msg1704.html#msg1704

My experiences with the Golden Cheetah were less than satisfactory, as mentioned in the above link, but my physical fitness improved markedly during its ownership!

Regards,

Frank.

G’day Franco,

The same outboard has been incorrectly referred to as the Golden Cheetah in a number of different places over the years. The correct name, as confirmed through old adverts, brochures and articles etc is however Gold Cheetah.



As with all engines reliability is dependent upon maintenance and/or lack thereof. The biggest issue with these was crank case vapours entering the ignition box and causing all sorts of problems, however all easily fixed by replacing the seal that the drive mechanism to the points set passed through.

I can also see potential issues with the crank design ie when used in mower applications, but unlikely in marine unless of course the boat was run aground with engine running. The shear-pin and tilt mechanism would offer some protection, but I’m sure all would agree this type of abuse is less than desirable even with current technology outboards!

Whilst I acknowledge and agree these engines were not without issues, they are still part of our history and for that reason, they are worthy of being rescued.
 
Regards,

Yes AusAnzani has very high standards in his workmanship and it sure shows in all of his projects that I have seen.

Hi AusAnzani,

I love to see your restorations, I have followed your work over on the mower forum and it is first rate.  A beautiful piece of art, that's what I see in engines.  I also hope to see some more of your Trojan engined outboard soon.  Well done mate :-)

Thank you Paul,

That Seacraft Tornado is great little outboard, in fact its one of my favorites.

It starts and runs fine and is already semi-restored thanks to the previous owner. I have lots to do before I get to that one, but hopefully it wont be too long.

Regards,
