I have a 1984 Renken with an Omc Engine and sern drive. The boat sat for several years before I purchased it. I got the engine going but recently noticed oil leaking around the Front main seal or crankshaft seal. I was wondering if anyone could give me advise as to any quick solutions or maybe tell me a ball park of what it migh cost to fix. I have replaced these seals in cars before but never a boat. Any help would be greatly apreciated!
