Can run the boat flawlessly for 20-30 minutes and then motor will cut out for a split second, then it will do the same thing a little more frequently 5 min or so. Have change plugs, coils, fuel separator, fuel filter. Then I was told about a Prop bore sleeve that helps keep the exhaust going through the prop properly. Took it out and thought it fixed it... and RPMs and MPH drove it at 4500 RPM for and hour straight no cut out. Then the second time I took it out it had the same issue same time frame as before.. Hopefully there is some help out there.
