Location: Cedarburg, Wisconsin | When I set my rig up, I played with props, tried 4 different ones. One was a 21" aluminum with no vents, one was a 23" over hub 4 blade stainless, one a 3 blade stainless vented 21" pitch, and a 3 bladed nonvented aluminum 23" pitch. It made hardly any difference at all when I switched them speedwise, less than 2 mph. Rpms changed but the speed didn't. Why? It didn't make any sense! Well, it was from the motor being too low. When I got the height right, then the props made a world of difference, adding about 7 mph finally. So, that's why I say get the height right first. I figure that if you dial the rig in at the wrong height, the prop that works best will probably not work very well at all when you raise the motor to optimum because you will be out of the correct rpm range, again. But I could be wrong, its happened before. |
