Running a Ranger Z520 with a 225 HPDI that Hydrotech rebuilt with a phase 2 kit. On dyno it made 285hp at 6100 rpms, rev limiter set to 6150. Running a 25p T1, worked by Johns Hot props and spinning it at 5800rpms running 70 with just myself and a light load. Slidemaster JP set at 2in PTP, great water pressure. Hole shot is good, just wondering if I can get my RPMs up a bit. I can keep trimming the motor and really kite the bow and start to get some more RPMs but it wants to walk really bad, I’m having a tough time keeping the boat on pad and driving through the chine walk. Over all happy with the performance but would like to have it set up to perform to its potential. Should I raise my JP some more or maybe have a little more cup added to help with lift? I figured that the boat/motor combo would run low 70’s no problem. I’m not big on speed and I would rather have the hole shot and midrange but curious if there is a little more to be had. Thanks in advance.
