Re: Nissan outboard loses power after operating at full power after about a minute

no none of the plugs were like you said they were all the same. alittle. wet and looked good
I thought it was rich fual. could have been water.??? .I try to fix them myself and do most of the time I do . I thought they would have the right testing equipment that I dont have. but they just guess like I do

There should be a thin film of oil lining every internal part of the engine, including the plugs and cylinder walls. This means water will bead up into droplets, whereas fuel oils maybe dispersed into a film covering the entire surface. if there were droplets it is water, a thin wet film is fuel.
