Motor starts fine, idles fines but sometimes when taking off, motor will not accelerate. RPMs come up some but boat wont take off. Ive noticed a couple times when turning left engine will take off. Ive tried pumping primer bulb when throttling up but no difference. Seems to throttle up fine out of the water

New plugs, replaced some wiring that has insulation falling apart, rebuild fuel pump & water pump, compression around 120 for all cylinders
