I am selling this engine \"as is\". Buyer is responsible for shipping, which should be around $300 additional
This engine came with my Q-1 Quickie Aircraft when I purchased it in July. The engine was put on the aircraft about 3 years ago, but has zero hours on it per the aircrafts previous owner. The aircraft was always hangared. I am replacing the engine with a 4 stroke 65 hp engine. This engine develops 28hp at 4200 rpm and is a 2 stroke. I was told the engine has \"0\" time. The serial number is SD 83 70. I was told that means the engine was manufactured in 1983 and was the 70th manufactured that year. I am selling it \"as is\". It has some surface rust on the exhaust collector. it comes with a muffler.
