An Embarrassment to the entire boating community.
Keep in mind these motors are meant for race type boats with very flat bottoms or Hydro's. They might be okay on the lightest of Feathercrafts like a Flash or similar. The lower unit gears aren't meant to push a heavy load and the Horsepower is developed at HIGH RPM. They have no neutral. If you put one of these on a Feather Craft type boat that weighs more than 150 pounds plus driver and whatever else you'll be lucky to get it on plane. IMHO they are way cool but not practical on a Feathercraft. This is the type bosat they are meant for. This is my DeSilva.
Please don't let me kick off a sort of "slide rule vs computer" debate but it would be interesting to do a stress simulation on a solidworks model to verify the specified power limitations. BTW, age and condition are critical. A buddy and I was removing the transom wood today and many of the bolts easily broke as we tried to remove them. Mainly from corrosion likely due to improper wood treatment and badly filled unused motor mounting holes.
