Prop comparison

[Thomas Augustin]

Any advice on changing stock 1.8 pitch 3 blade to a 1.74 pitch 4 blade or 2.6 pitch cleaver 4 blade on Zelos 48” gas 30cc. All are the same diameter 67mm

The more blades, the more load the motor will see. No matter if the dia and pitch are the same. There will be more blade in below the waterline. I have no experience with that boat.
