      I don't remember what size or horsepower engine you're looking for, and the
      Restless web page only provides numbers for cubic inch displacement and
      engine weight, not recommended horsepower:


      ... but Kawasaki makes a nice looking power plant that appears to be a good
      fit for some inboard designs. These two links show the biggest (29 HP) and
      smallest (16 HP) in Kawasaki's line of overhead valve water-cooled v-twin
      engines. They have five more models in between these sizes:


      The ATV guys rave about these engines. Maybe they know something that the
      boating community does not?

      If Restless needs more HP than one of these engines can provide, a person
      might buy and install two of them. Two of the largest 29 HP Kawasaki's will
      weigh a total of only 250 pounds -- and that's 100 pounds LESS than the
      engine weight specified by William Atkin.

      Just think, a twin-engine Restless with a total of 58 HP, and each engine
      driving its own propeller. Two completely independent drive systems for the
      ultimate in safety and redundancy.

      And wow, what a hot rod!
