I finally got the spectra 20 running like a timex. still screwing with the temp being to high. but changing the coolant lines up to #10 made a differance. now. when im cruising on a plane then stab it the boat jumps and goes but the rpm shoot up just before. like slipping a clutch. im sure the pump is stock with a loader in the grate. stock jc bowl and a place diverter. any ideas? i will not pretend to know about jets but i have a hell of a fun time driving it.
