BF75good start, idle,no power

[Tom Boulanger]

hi Guys,
I have a 2001 BF75A. It has new fuel pumps,compression is within specified tolerences on all cyclinders,new fuel line complete back to the tank,new fuel separator, Rebuilt all 4 carbs. New oil and filter,new internal fuel filter in engine compartment. new plugs.Engine runs cool with plenty of water flow.The engine starts good and idles good.When i cruising at idle to about 1/3 throttle everything seems fine. When I throttle up more then that the boat seems boggy and will not plane off. Do you guys know of any issues I should be exploring?

Thanks
Tom

Are you getting spark on all the cylinders? Might be a cylinder not firing.

You might check the coils. One of mine went bad and had somewhat similar issues.
