I should be most interested and grateful if anyone can tell me if they have changed the propellor on a Dufour 27 from a 2 bladed to a 3 bladed. And how to do it and what effects it had on the boat. Many thanks.
I switched from the original Dufour2 blade folding propeller to a 3 blade 13 inched fixed proper and did not notice any difference. Two years later I switched to a 2 blade Flex-O-Fold and I have been pleased with it for the last 7 years. It is not just the type of propeller it is the pitch and diameter and the manufacture that make the difference.
