i hav a 40 hp with a 4 blade aluminum prop . bought a 3 blade ss prop #ys50srd-16p. boat is a 20 ft pontoon . what change will it make in the performance of the pontoon. it now runs 16 mph with the 4 blade . checked with GPS.
tried the prop no speed . to much bite . anyone can use it i will sell it for $125.00 or trade it for a 4 blade aluninum prop 11 pitch or somethingclose
