Need some ideas. I just repowered my 2010 bay boat with a DF175 Suzuki. She plains at around 3200 rpms. With motor tilited down and trimtabs barely applied when I have to make a tight turn I lose speed and sounds like the prop os losing its bite. Currently have a 16x20 prop tghat gives me 5900 rpms at WOT. I run thje white oak and have to have the turn capabilities since it is a winding path to get from Stella to the Swansboro bridge. Any ideas out there?
