i probably inquired last fall about this,if so i apologize..anyway,i have a 22 ranger 518 with v8 200.the boat came with a 22 fury.it runs ok.it turns somewhere between 56 and 5700 rpm.the speed is some where between 64 and 67.i need to get a second prop anyway for a spare.so my question would be,could i try a 21 pitch fury or 22 tempest and expect similiar results?im thinking the 21 would give me more rpm,but i dont want to sacrifice speed due to less pitch.so im wondering if less pitch automatically equals less speed?or due to turning less pitch at higher rpm sorts equal it out?
