The replacement motor so far with just over 2 hours has hit 59.9 mph at around 5,800ish rpm, also with the Fury prop. The rpm on the smartcraft is fluctuating some so hard to give accurate rpm readings. Of course conditions altered the numbers somewhat which may explain the lower readings. With the 4 stroke Pro XS the 23in. Tempest speed was around 58mph but the tach hit 6,100rpm so I came off the throttle right away. I'm still wondering if it would be worth the money to reprop the 23in. Tempest to 24inch. Thanks guys for the encouraging replies.
