Thanks for the quick response. I suspected what you said. The engines and props enter the water about 30" behind the hull because of the bracket. Am I still ok with the 24" X 9" with the water flow???
I have a 2520 Sport Cabin DV with bracket mounted 225hp. four stroke Yamahas. The original trim tabs are far to small. Can I install instead of the original 12" X 12" tabs 9" X 24" and improve performance? Will the added size effect my engines and props because of the change in water flow...
