My engine is a 2007 with 194 hrs on it. If out on the water there is a slick coming on the surface in little bursts every 10 seconds or so whilst trolling at 1000rpm. When stood still on tickover the slick seems constant and extreme. Fuel economy seems very bad but i could be imagining this ( 5 litres fuel in 4hrs at 1000rpm) There is not a smell of petrol so i guess its oil. The cavitation plates have oil thats clear and clean looking on them but the engine oil levels not going down at all or so it seems. I run the engine in a barrel of water and theres nothing on the surface hardly. and the engine runs perfect too. Wheres it coming from, my head is wrecked ☺
 
Ive checked more thoroughly today, and the oil is clearly dripping from the small exhaust hole directly below the engine cowl clip. The oil is still clear and viscous. Is this a sign of broken rings or scarred barrel ? Will a compression test tell me anything as the engine is running perfectly. Help☺
