Twin 2022 300 AP zukes while running/ cruising they will sporadically drop rpm by 1000 rpm or so. The rpm will drop randomly and both motors have never dropped out at the same time. No codes have been thrown. These are brand new install, still in the 10 hour break in period. Motors are fly by wire. New fuel lines, filters, battery cables when installed. Have checked all connections and such and nothing appears loose or out of place. Any suggestions on how to proceed? Its sporadic enough where a dealer my have trouble duplicating the issue.
