Noticed oil slick on the floor under the prop when took the boat out today. Motor oil leaking out from the lower exhaust. Put it in the water and started it. Lots of smoke and sounds like one cylinder is miss firing. What could cause this? SN G025398; can't find any model info other than this on a small tag. The oil leaking is clean engine oil. Must be coming through the engine from the reservoir.
