Review on ๐Ÿ‹ Davis Instruments XL Whale Tail Hydrofoil Stabilizer by Luckie Coonrod

Revainrating 5 out of 5

Actually worked in my app

My boat is very heavy with tiller, kicker, three batteries and a small fuel tank. Add me and I couldn't keep it going faster than 15mph on the plane. Anything above that rate would be dangerous, start at 26-27 mph and just go bad. I also modified the plate so I could easily mount it forward using three brackets on each side. I lost 1 mph at the top, 25 mph but it doesn't matter I still could never stay over 15, even if I had someone at the bow I would do 17 mph in an hour. when it's quiet, but now there's a lot more control over the nose. I have a 40hp Mers, 3 cylinder efi 20" shaft in a 650lb 17ft Fishmaster, universal fishing body. My 25hp didn't mess with the case, it's 100 pounds lighter so it should be the weight issue on the blades. Still works great. I removed the 7/16 stainless steel bolts and replaced them with 1/4" hex bolts with new locknuts. The round head reduces drag slightly.

Pros
  • Increases fuel efficiency
Cons
  • I don't remember
