Ranger Z519 and Fury 4; Is there any more to get out of it?
2016 Ranger Z519
2016 Mercury225 Pro SX
10 Inch Slidemaster Manual Jackplate
24 Pitch Fury-4
2 inch Prop to Pad
Max 70.5 MPH AT 5840 rpm
Boat was originally set up at 2 ½ inches prop to pad. Was running the same speed and RPM. But it chined pretty badly above 55 MPH. I raised the motor ½ inch this weekend. Chine just about disappeared. Water pressure still good but didn’t really gain any RPM or speed.
Weight included me, full live wells and a half tank of gas. Air temp was close to 90 degrees and water temp at 80. From what I could see, roster tail is about even with the top of the cowling.
When I run the numbers through the Merc calculator, it come out to about 9% slip. So the question is, is it even worth messing with? Is there anything more I can do? Will having the prop worked gain me any mph? Is it worth raising the motor any more? Still plenty of water pressure left.
I spend most of my time running between 45 and 50. Just like to put the hammer down once in a while.

Then I guess I'll be happy with it and quit screwing around. For a while. Thanks for the feedback.
