I have a brand new pontoon with a Evenrude E-etc 40 engine.
Engine runs rough at mid rpm’s. From about 2600 to 3500.
Above 4000 rpm runs fine. From idle to 2500 rpm is also good.
I hate to make a 90 minute drive back to dealer so they can keep my boat for weeks during prime time summer usage!
I’m using premium gas, none ethanol!
Anybody have a similar problem with brand new engine??
