I have a Mercury 8hp outboard that came with the boat I bought last year. Its about 10 years old and sat unused for several years. When I ran it for the first time it ran fine, then wouldn't run again. The local outboard repair shop says that the top crank seal is spun, probably due to rust on the crank. The top cylinder then won't hold compression. They estimate about $600 to replace the seal but warn that damage to the crankshaft may make it unusable. Does this sound right? Is this engine worth working on? Thanks Phil Keys "Kathy K" 1982 Sundowner 30 tug yacht Port Hadlock, WA 98339
