I'm interested in getting one of the "ducted" prop guards for increased
fuel
efficiency and earlier planing and was curious if anyone has any
experience
with these. I'll be using it on a 19' bowrider with a 210hp Mercruiser
I/O.
One concern was an increased risk to the outdrive tilt mechanism if you
hit
something with the guard, rather than just damaging the prop without it.
Don't know if that's a valid concern or not. Any experiences would be
greatly appreciated.


My boat is the same as yours in size and power (19' bowrider with a 210hp
Mercruiser I/O). I installed a hydrofoil (Stingray) and am happy with the
positive results (earlier planing) although I have not checked the effect on
fuel economy.
