Does anyone know the largest diameter propellor that can be fitted to the old style Contest 31? I am re-engining and need a new prop as the new engine turns the opposite way. The current prop is 11" diameter on the old 25HP Volvo MD2B and I will be fitting a 27HP engine. I think 11" is a bit small for the engine and would like to order a new one before the boat is out of the water if possible.
