 What is a safe high RPM i should shoot for?

6000 with no passengers, livewells empty and low on fuel.... is what they say.

Dang,  i need to do some work, Kinda wanted to get a jackplate before i mess with props.  When it was my dads boat he didnt have hardly anything in it and the best i ever saw alone was 5700-5800

Close enough.  Does it have a hole shot problem?   If not I'd leave it alone.

 

Maybe your Chris Carson Crankcase Stuffers will get it there 🤣😂😅

Full well, fairly full tank me and a buddy it is a little sluggish but has never let me down.   I got it full of tackle and way to many rods and other BS.    My dad pretty much only had a crappie rod and one 3700 plano lol.    Ill probably leave it alone.  I spent way to much money on my last boat chasing 2-3 mph.  not really worth it

Nope, it sure isn't.    That XR6 is gonna puke a piston or two, no matter what, anyway.   😊

Are these motors known to pop...  Everyone says these are reliable for a merc

The XR2 was/is the reliability winner. 2.0L.

The XR4 is a 2.4L steel bore version of the original Black Max, but with a different ignition system.  

The XR6 was the first 2.5L, with taller gears, and is the hands down performance winner of the XR family. It was the XR6 block that was chosen for the first run of EFI Merc's (and they were great).   The weak spots of all the Merc V6's has always been the oil pump drive gear, and the cooling system.   Why they never attempted to improve either, over time, is a mystery. The only change they ever made was going from a 1 piece o/i drive gear to a 2 piece drive gear....which didn't improve anything that I am aware of.  

You can eliminate o/i failure by terminating the system and mixing your fuel, but there's nothing you can do to keep running temperatures even and consistent throughout the RPM range.   The biggest killer of Merc V6's was the popularly of the HOTFOOT.   I believe that if those things had never become "a thing" then a lot less Merc V6's would have blown.
