So I've got an Action Craft 1720 Fly Fisher with a Yamaha F115 4 stroke that I am looking to re-prop with a 4 blade.. I having been looking hard at Powertech Props, particularly the SCD4 and RXB4 models in a 17 pitch. I know that the SCD4 model claims great stern lift whereas the RXB4 claims to be an in-between prop when it comes to stern/bow lift. Does anyone have any guidance on selection for this application? I don't believe Action Craft's are built to plow, so I don't want too much stern lift, but don't want to be porpoising either. Thanks for the input everyone!
