The motor like all the motors in the place I work are dump finds, a whole plethora of mid twentieth century stationary engines and outboards the blacksmith seems to collect with the idea of getting them going but is vague as to what purpose they will be put beyond just having a collection of old stationary engines with no application.
But this motor being an extreme rarity is of particular interest in that no one has heard nor seen one and even the American's with their vintage Easton's Vikings deny they were ever built in the UK let alone Southend on Sea and it's appearance does not match anything they know of, yet it us a Viking outboard made out of aluminium which would fit post war UK production constraints ( the same reason why Land Rover went with aluminium, lots of it about post war, but steel was rationed).
This thing is traditionally British in design, an over engineered lump with a water jacket uptake pump that can be run dry as it is not a rubber vaned affair particular to nearly every other outboard, but an archimedean screw, the same principle of operation as the archimedean screws used for irrigation, and the gear box on this thing has an inspection port requiring EP-90, it has more in common with a land based machine than a machine used for marine use and all that powered by a piddly little two stroke.
But my effort which was more interest than anything else, I got the thing to fire and run for about half a minute, the longest it has run beyond a few puffs of smoke, but concluded the reason why it would not run properly was because of the fact that compression was being lost through worn crankshaft bearings, it was audible and in water, bubbles coming out of the exhaust spelled the same. I am confident the carb now works, I had to do a gen up on the principle of operation of a Zenith carb which did me good, but found the carb flanges to be warped, so these were flatted and new gaskets made. The ignition is fab what a spark so no problem there and the cylinder bore is unmarked, so the correct lubrication has been used in it's former life, whatever that lubrication ratio was. The induction I am confident now performs, leaving only the crank to sort out and last night at about seven pm I left a report for the blacksmith giving my findings. Piston rings, well it will surely come to that as well, but they might be a bit more difficult given we can find no data on this thing, but I will have a go.
If he is really interested, I will rebuild it, my labour is free, but he can buy the bearings and seals and with crank bearings replaced I am confident it will perform, it is an impressive little machine and as far as I can ascertain unique. It just happens the Blacksmith has an old boat that needs an old engine, the boat a Fairey something or other built with what was WW2 Motor torpedo boat hull technology and the fact that outside the smithy is an old WW2 gun boat is testimony to his interest in these things, it would be nice to get an odd engine working for an odd boat owned by an odd person who now has another odd person working in his smithy.
As it is the Blacksmith has offered me an apprenticeship to train as a Blacksmith, he says he needs to pass on his trade as is traditional with Blacksmiths but so far of all the helpers he has had no one aside from myself has shown any aptitude for the job, but then I have a metallurgy grounding in that I have been an amateur silversmith and jewellery maker for twenty odd years, blacksmithing to me is the heavy metal side of metal smithing and heavy metal and now death metal pumps out of the smithy speakers, bashing hot metal to Ramstein and now Haggard.
As to the engine repair thing that blacksmiths are asked to do from time to time, I was a plant and small tools repairman for ten years prior to my falling apart five years ago, so being apprenticed my machine repair skills will undoubtedly enhance the business.
