Finally installed my hydrofoil: "Tiger Shark VG" on the 90 Honda. Results were rewarding. The boat jumps on plane almost immediately with no bow-high segment as before. Planing speed in 1/2 to 1 foot water is 15.5 mph GPS. I can actually trim up significantly higher with no porpoising whatsoever. Top speed actually may have increased a bit to 40 mph GPS. Fairly hard turns didn't pop the prop out, either. All this with the motor on its lowest transom position. Checking (as best I could)at full throttle, I still couldn't see the hydrofoil showing: it may have had a thin sheet of spray passing over the top - not sure about that. I'm going to try moving the motor up at least one hole to see if it changes anything. Best $21.00 I ever spent!

Because of it's design I believe the 160 Dauntless will virtually always benefit from an engine mounted hydrofoil.

In my case I went with a SE Sport 300 (foil) on my 115 Merc., made my 160 Dauntless a whole new boat. :)

I did move the engine up one hole with good results. Prop does not break loose even in rough water.

I also recently installed a stingray fin on my 04 Dauntless 160 with a 115 Mercury classic. It has made a huge difference in planing at lower speeds and keeping the nose lower especially in rough water. The only complaint is the wake is significantly smaller which my wife say it makes skiing not as fun as before the fin was installed. This may be that the stern is not riding as low in the water as previoulsy. My top speed has decreased only by 2 mph. I had 4 adults and 2 children on board this weekend and still could reach 44 mph by GPS.

Good to read positive results from this hydrofoil. You're right about the wake: the boat is not "plowing" as much as before, i.e., not displacing as much water at speed, so the wake is lower. I also noticed I can travel in the "no wake" zones at a significantly higher rate of speed without creating any significant wake. I also have changed to carrying 1/2 tank (22+ gallons) most times. Only time I carry more is on anticipated long cruises with indefinite fueling locations. I think that adds both to the balance of the boat and top speed/efficiency.
