This was my first though. How much perfomance gain are you getting and will it offset the repair/replacement cost? Will most likely be replacement as I’m sure Bubba down at Bubba’ Marina, Boat Repair and All U Can Eat Seafood Shack won’t know how to buff that one out.

We really don't need more slow, no go or idle speed only zones.

I see the main reason it works. Acts like a ducted fan, not allowing thrusted water to sling out at right angles...forces more water straight back with most of the prop wash.
