{"product_id":"stuart-sirius-stock-code-1503","title":"Stuart Sirius","description":"\u003cp class=\"MsoNormal\"\u003eA well-made Stuart Sirius, twin-cylinder enclosed crankcase  engine. Designed in the 1930s by Stuart's as a small utility engine rather  than a model, many were coupled to dynamos pre-war to make workshop lighting  sets. Developing ½ hp at 100psi, the Sirius runs at high speed with a most  distinctive “purring” exhaust note.\u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eDuring the war the engine found use in a small portable 24 volt generator set  for operating military radio sets – a small metal case contained the engine,  dynamo and solid-fuel fired boiler.\u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eIn the 1950s, the engine found a new niche in the field of model powerboat  racing. With its high-revving power characteristics and good power-to-weight  ratio, the engine made an ideal power plant for larger boats.\u003c\/p\u003e  \u003cp class=\"MsoNormal\"\u003eThis engine is one of the best examples we have had. It runs very well, has the  extended sump with dipstick incorporated and is nicely painted.\u003c\/p\u003e    \u003cp class=\"MsoNormal\"\u003e\u003c\/p\u003e","brand":"Station Road Steam","offers":[{"title":"Default Title","offer_id":54009508528469,"sku":"1503","price":2600.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1023\/0094\/2677\/files\/1503-1.webp?v=1779897976","url":"https:\/\/stationroadsteam.com\/products\/stuart-sirius-stock-code-1503","provider":"Station Road Steam","version":"1.0","type":"link"}
