Darr? Most 38TS’s have XR’s or sport masters....SCX’s -4 s aren’t a common setup, so you might want to provide the gear ratio and if you’re running SSM or Bravo style props, what rpms the engine make max power

engine builder is Gary Kinkade in havasu
I am not the original owner assume xdimension is stock
haven’t purchased new props yet was waiting for recommendation since nobody seems to swap Props
Was just looking through classifieds trying to find boats with similar power to get an idea prop selection but now I’m more confused than ever from what I see the same boats with 525 hp are running The same Props Merc 30p 4blade as I ran with old motors ran 97mph at 5700 rpm. New motors make good power up to 6000rpm
