So we refurbished our spare prop which was in excellent condition. The boat was pulled and we are swapping out the prop as the one that was on there had some damage, etc.
The original prop was a 22" 16 pitch. The prop I want to put on is a 24" 17 pitch.
I know the 1 degree of pitch is about 100 RPMS. I wanted to get a little better speed out of the boat as I was only hitting 6 knots or so at 1675 RPMS. I am concerned that I may be over propping too much going to the new prop.
I am running a FL120 and a 2.10:1 Velvet Drive. The boat weighs around 19,000 lbs and 35.6' by 13.6'
Anyone have any experience with this? I am on the hard until Monday morning. Maybe I should try it and if it loads the motor too hard buy a new prop. I know the true test is to run it up to the rated 2500RPMS but I would not ever run the boat at that speed. Everything I have read is that they like 1600 to 1700 all day long. I have also read that it was not uncommon to over prop to get more speed knowing you won't ever get to the max rated RPM. I just don't want to hurt anything either.
Thanks for your help.
