71.4 with a stock pump at 6200rpms:jawdrop:
Is that to high?
Will a shoe and ride plate, droop and diverter bring that down some?
Or do I need a new inpeller?
What should I run.
Its a 1981 18ft Crusader (splash of southwind) with a 468 and berkeley 12JG.
what impeller do you have.tes imo thats way to high rpm for the speed you were running,have you verified if the tach is 100 percent on the money,might look into that first.if so then i would be looking into the pump.was it cavitating any at all any funny things going on.:idea:
