Hello,<br /><br />Have a Volvo 270 outdrive. It is on a Bayliner 2550 Sierra with a 10'6" beam. I have bought a spare outdrive for the boat. The spare outdrive has a gear ration of 2 1/4 to 1. <br /><br />My regular outdrive gives me 26mph at 3400 rpm. <br /><br />Does anyone know what the ratio...
