to cut a long story short (at least to my simplistic understanding) outboards are water cooled and so run cooler. chainsaws, motorbikes etc are air cooled so generally hotter. the oil is designed for the different temperatures. I know someone who has used bike 2 stroke in his jetski for 5 years, but his plugs do seem to get coked/oiled up more than normal.
