The turbo charger is bolted to/part of the exhaust manifold, and here is where the danger part comes in, when the turbo pipe leaks it sprays oil on to the exhaust. If the seal has failed and it will allow oil to drain around the Driveshaft when the engine oil pressure is high enough to push thru the seal. Any of these leaks needs immediate attention. why should i put marine 2 stroke oil in my outboard and not normal 2 stroke oil does it really matter? y should i pay 3 times as much for marine oil for my outboard when it works perfectly well with normal everyday 2 stroke oil? it's not that i'm powering up for hours at a time i only speed about for 5 minutes max at any one time. In a dry sump system, oil is instead pumped to an external reservoir. 1995 mariner 150 So a few weeks ago my outboard was leaking a little black oil from the lower unit "holes". If the shaft seal is out will it pump oil up the midsection?. A very common oil leak is at the turbo pedestal o-rings.
