I went to look at a used 2 stroke nissan 2 cylinder outboard at an Estate sale the other day ... It was stored on its side for like 10 years ... I stood it up and lower lube ran out of the exhaust ! up by the powerhead I told the seller it needed the LU Re-sealed and wanted them to reduce the price accordingly Some smart azz relative told me to change LU lube and run it ! I say BS 1 It needs new seals ... List wisdom ?
