Please do not take this personally.....I have seen more boaters ^%&$ up their boats by "trying to get something for nothing".
On large vessels, we have pyrometers which measure exhaust
gas temperature. This allows us to run the mains without overloading them.
On a sailing yacht that I was Chief Engineer
, we had Hundestadt Variable Pich props.....by observing the EGT I could dial in the pitch for optimum performance............I had to disable the system, because when I was off watch...the owner or his assholian son-in-law would futz with it to try to make the boat go faster. From my berth in the crews quarters, I could tell when they were fiddling with it.
You will have more power for manoevering with a less pitched prop....
You won't be lugging the engine.
How much does it smoke?
