Cuts out after hitting wave

[Bobby]

My 96 Sport w/ GT-40 EFI will cut out for a split second after I drive over a boat wave. Once I pass over the waves and get back to smooth water everything is fine. Anyone know how to get this taken care of?

Check for lose ignition connection under the dash. Often a lose dashboard, or connection can do that.

Not sure if yours would be the same as mine was but mine would do that sometimes. It was a 2000 superair with gt40 it was the glass fuse at the battery. It was a plunger type fuse holder and it was worn. Connection would come loose and boat would die. Change the fuse holder and never had the issue again.

Check the battery cables also check the grounds on motor make sure they are clean and tight.
