"since doing an oil change the other day, one of my 360's acts funny above 3000rpm. I can get both motors to 3400ish RPM but the starboard engine backs itself down to 3000 on its own. Sometimes it will jump back up but not often. I back both engines down to 2800 to cruise and it's smooth. Pressure hovers around 40psi. temp is 160ish and I used 25w40 weight oil. It could just be a coincidence that this is happening after the oil change...or not. Fuel is less than a month old. and again, it's only happening on one engine. issue presents low-level vibrations and hum when it happens...just as when engines are out of sync before I trim them both even. any thoughts?"
