The fuel pump supplies way more gas than the engine needs. If it is a fuel
issue it would have to be at the carburator. If it is at idle then it might
just be the increased back pressure at the exhaust.

If the fuel pickup in your tank is in the aftermost part... likely, and
the fuel level is low, when a following sea comes up your behind it causes
the transom to be much higher than normal and the bow to be much lower
than normal. This could cause a momentary fuel starvation event due to
attitude, no?

With each "push" of a choppy following sea, the Chevy V6 in my 22'
Grady White I/O seems to want to die. This also happens when the
boat gets into any kind of a repetitive wave pattern. It is as if
something cuts off the fuel supply as the boat surges forward, and
restores it as it goes up the crest of the next wave. (Something in
the fuel tank perhaps?)
If it isn't something in the tank, where else would I look? What-
ever, it is definitely a function of up-and-down hull motion.
Your help is much appreciated! Thank you!
