Engine bogging after jumping waves
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?

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.
