She starts great idle is smooth revs good on the hose once in the water is slugish to the point it takes 10 to 15 seconds to get on plane.
120psi on both cyl
rebuilt carb (have had the fuel screws all over the place about a 1/32 of a turn at a time)
New plugs (great spark nearly made me pee myself) will jump 1/2"
Fresh gas
Fuel switch bypass(just to rule it out)

What type of fuel filter you running the stock water seperator or the inline?... i have a 750 in a 650sx and this summer i had the same issue.... was just a lack of fuel... is your engine running hot?
