Well the dealer pushes Evinrude first, he does have Mercury and Suzuki also but is very insistent that the two stroke Evinrude is by far my best option. My problem is I have always been a Mercury guy, I currently own a 2018 Mercury115 HP four stroke command thrust and love it, cant hear it run and have very good hole and mid range power on my 20 aluminum boat. The boat I`m getting is same length (20ft) and only 4 inches wider but they recommend from a 115 to a 200hp dealer says 150hp is perfect?
