I've got a 2008 621 RangerVS with a 2010 250HO. There was a Cyclone 19-4 blade prop on it when installed at the dealer, which was changed to a Cyclone 21-4 blade . After running the boat a couple of times, I get no hole shot, and 5000 rpm max, speed is about 52-55 mph. Any suggestions or recommendations on better performance would be appreciated. I am a walleye guy so I know nothing about boat performance, only how to catch bottom feeders. Thanks
