Review on ๐Ÿ‹ Davis Instruments XL Whale Tail Hydrofoil Stabilizer by Ron Patel

Revainrating 4 out of 5

May need modification for your application

I first installed it when it arrived but found it still had no trim range at higher rpm so I have it modified so it can be moved further forward. Now it works for both aircraft and as a cavitation plate. I have it on a 40hp Mercury 4 stroke and the difference was like night and day. The engine feels more powerful, glides instantly, revs sharper and ramps up smoothly to higher revs with little to no cavitation. Great addition for performance, easy to modify and use as a cavitation plate.

Pros
  • Increases top speed and saves fuel in most applications
Cons
  • Has issues
