Why would anyone who is aware enough to purposely overprop their boat...purposely lug the engine?
The mistake is thinking that matching the boat , engine prop and cruise speed is lugging.
The boat is ONLY "overproped " if the operator attempts to operate outside the range the boat was set up for.
To assist in not harming the engine a slight bit of operator understanding is required , the RED line on the tachometer has meaning , as does the RED line on the EGT gauge.
"Thinking about the downside elements 5% isn't enough to justify over propping in my opinion. Just not worth it. "
Would moving the cruise RPM from 1900 , down to 1500 be worth it?
There is lots more to Efficiency than just fuel burn
