It is NOT the same, and should NOT be used.
Bikes, lawn mowers etc are air cooled and so run much hotter than a water cooled outboard (which almost all are, and certainly any recent reasonably sized one). The result is that your engine will not be properly lubed - prolonged use is likely to be bad, potentially terminal, and short use is likely to result in fouling of plugs etc.
2 stroke outboards use TCW3 grade oil, unless you've got some fance modern direct injection (e.g. Etec) engine which will be even more sensitive to using the wrong oil.
