Can I change my Merc outboard to a jet pump?
Just to name two disadvantages. :^) Their main advantage, if
it's what you want/need is the shallow water capability.
I saw a lot of these in Alaska. The guys said they do it because of rocks. Even
at idle speed a prop won't survive a kiss with a rock. The jet bounces off, up
until the speed that blunt force becomes an issue.
