Hey Garbubba, I installed the Lenco's on my V20 Fish very recently, and have used the boat twice since.
Install was easy, just be sure to use plenty 3M 5200 around all holes in transom.
The tabs work great and react very fast, so pay attention.
My only complaint is that the static setting should be more aggressive. I set mine to the recommended spot and would have liked more trim. Instead of remounting the acuator I am going to put a 1" spacer between the tab and acuator.
The ride quality definetly got better. I have not done any fuel comparisons yet.
Trim tabs definetly are worth the $$$.
Now all I need is that new engine.
The long lost Cbuzz ;D
