My 454 runs perfect in flat water all the way up to full throttle... When I head out the inlet jumping large waves and the boat goes on a 45 degree angle, when I land the boat starts starving for fuel damn near turning off...any ideas thanks guys

My fist guess would be to check the float level in the carb

same comment!

the float bounces and causes a brief over rich condition,pretty common with holley carbs.

Had the same thing happen it my 28 Pantera with a 525SC. The high launch angle and pulling back on the throttle in the air would cause the bowls to overfill and flood the engine.

so, we all know what's the problem, but is there a fix to this? lower the float?

fuel injection

Make sure you have brass floats. The plastic/nylon ones are more "bouncy", so to speak.

Some of the old school racers would epoxy a small block of foam or plastic in the bowl under the float, this keeps it from bouncing so far down, some swear by it.

Keep the fuel pressure right at 5 lbs, you might need a regulator. Higher pressure makes it harder for the float to keep the valve closed.

Holley also makse an offroad needle/seat
