Just setting up a second hand

Just setting up a second hand 175hp with a 17 inch prop.It's going on a 20 foot glass boat which carries 300l of feul. What rev range should I be looking for? 5500rpm ? or 5800rpm at W.O.T
 
When i put a 15 inch prop on w

When i put a 15 inch prop on with two men and 300 litres of fuel i get 5800rpm.I have not tried the 17 inch prop yet but i think it will be around 5400 RPM.Is this too low ?
