at this time managing the stainless three blade K16 that arrived with it but I'm not getting in excess of 5200rpm at WOT at 36mph lightly loaded. The boat has a electricity pole and removeable trolling motor. Does any one else have this setup and what prop are you getting achievement with? I've kind of narrowed it down to the powertech scd fifteen three blade, (only from phone exploration) but I'd like much more input from other house owners. Thanks in progress.
