23 septre i.o.prop size info

IT is funny this topic should come up. If I've got the same question and the same configuration. I've held off a asking the question because I plan to repower soon, and will likely try and put in a 350 CID Vortex putting out 310-325 horsepower.

One thing not mentioned previously is that some of these boats have tanks holding as much as 145 gallons (mine for example). That is nearly 900 pounds of fuel. Also, in my case, the aluminum prop is cupped. However, I believe mine has reached 4000-4100 RPM. The above mentioned target WOT RPM range is accurate though.

As I said, I will be a REAL interested in the results of this.
