Known a Coventry Victor super speed, or S.S.8, as the 8 denoting the HP of the engine.
This outboard is a petrol Coventry Victor engine which was also used in a water cooled configuration as an inboard boat engine, this one is mounted on an outboard leg.
The engine model is more commonly known as a coventry Midget and was also made as an air cooled engine, the only differences were the finned cylinder heads, plus a finned flywheel for air flow, but basically it's the same twin side valve engine.
M.A.1 – 285cc AIR
M.A.2 – 340cc AIR
M.W.1 – 285cc WATER
M.W.2 – 340cc WATER
This Coventry Victor was sold as the only silent vibrationless four- stroke, twin-opposed outboard.
I always liked the odd looking engines especially the flat twins.
They did do two exhaust versions one was the standard aluminium exhaust with the Coventry Victor name embossed on it, as seen in all the Coventry outboard ads.
The second exhaust was listed in the parts book as a special silencer and was steel, luckily the previous owner had the original parts book and manual, which are quite rare.
My Coventry Victor was probably made around 1948 and had been sitting in a garage for 30 years, but it was in better condition than I would have expected.
I have only seen a handful of other Coventry Victor outboards, some incomplete and others in museums mostly, but only one or two with all the brass fittings like my one.
