Display purposes only I would think.
I made a nice outboard stand out of a clarke engine stand, nice and solid and has wheels.
Zimmer frames seen to be the easy option for a stand, also something to fall back on.
If you like top heavy gas powered vehicles do some searching for WWII era wood gas fueled bikes,That one for sale near you is not really that out to lunch. If you saw a 110 pound hot chick on the back of his bike you would'nt ID it as strange or akward. Saftey wise I don't see it as a problem any more so then flying down the highway at 130 kms/hr on any other organ donar machine. Around here we tons of lpg converted pickup trucks with massive LPG tanks bolted into the pick up box. Some years ago LPG was cheaper to run per km then Gasoline. Now it is not. The up side to it though is trouble free carbs and cooler running. In the outboard world the chinese are now shipping small LPG fueled OBs that take a cylinder in the cowling. should decimate the liquid fuel makrket before long if folks catch on to the many benfits. No winterization, no drips in the trunk, etc etc.
The Mercury set up is a gross breach of many regulations, ordnances and best practice - something should be done about it. I feel I can contribute sensible guidance in this respect - I expect a fee to follow of course- cheques fine.
Firstly there is clearly a trip hazard in the operator area - that ladder could cause someone to trip and injure themselves - totally unacceptable.
And as has been pointed out, although there is a safety kill lanyard it is not visibly attached to the operator - that could indicate tacit approval of bad practice. John should be informed lest his site is blamed for promoting slack procedures.
And where are the clearly marked signs to the exit route from the test area, signage, low level emergency back up lighting etc? Clearly dangerous and unprofesional - a cowboy engine tester workplace extravaganza.
And it is not even clear if the opeator is wearing a correctly adjusted lifejacket which has been serviced within the last 12 months. As this is boating related site safety safety safety has to be repeated, again and again, and again. That water is after all quite deep.
Even more lucrative -sorry I meant to say important - nowadays is due regard for the environment. Where is there any evidence that an environmental impact survey has been completed prior to placing the water butt and holding up thingy on that grass? Any number of organisms, plankton related creatures and so on could be endangered by that hazardous blocking out of light on life supporting soil? It may be inconvenient but worms have feelings - and indeed they have their (non) human rights which are enshrined in various statutes.
Other than these failing however I can't see much wrong with it.
