Twins. Does one work harder than the other?

[SeaKaye12]

My neighbor has twin Yam 115's on his fishing boat. His mechanic told him that the port engine "works harder" than the starboard engine; presumably because of prop load.

I had never heard this. Is it true? And, if so...is it customary at all for the engines to be swapped around after a certain number of hours?

Thanks for your time and interest,

Chuck

If they are counter rotating engines, there is no real reason for this theory.
