...and are notoriously unreliable compared to most mechanical contrivances.

since it is pure editorial opinion, most likely from someone who extrapolated one bad experience to the entire population. The reliability of any mechanical contrivance would suffer from being left idle most of the time then run hard in a harsh environment.

I removed this:

Marine engine manufacturers are now designing an outboard motor to run on hydrogen. It makes sense to try and utilize the abundance of water surrounding the vessel to fuel the engine.

Since it is nonsense. Hydrogen could ofcourse be used as fuel, but it costs more thermal/electric energy to split water into hydrogen and oxygen than can be recovered from burning hydrogen (because 100% efficiency is impossible). So whatever the power source, directly using it to propel the watercraft is more efficient. Not to mention the weight of the extra machinery that would be required.

[edit] Illegal engines

Most types of two-strokes that uses carburetor is illegal in EU and other countries like Norway, because they pollute to much, especially NOx... Think this happened in 2007, and if true, it should be added in the article. —Preceding unsigned comment added by 83.108.241.197 (talk) 21:44, 7 September 2007 (UTC)
