Default Running on one engine
In article ,
says...


I have done controlled tests with our boat, running slowly at around 7
kts on a single engine, and letting the idle prop spin freely. The
fuel save was 20% at best.

That's a significant savings. Since you didn't lock down the idling
shaft, what are the downsides?
