I’ve got a 20 foot aluminum deep V with a Yamaha F200B (4 cylinder four stroke). Top end doesn’t concern me as I rarely run the engine above 4,000 RPM where the VVT system kicks in and fuel economy starts dropping. The Enertia Eco props sound like a good fit, but they are a massive 16” diameter. They were designed for larger boats running dual, triple, or quad motors. Hopefully someone in here has run one on a freshwater fishing boat and can share their thoughts.
