It isn't a Z519. It is a 1999 519DVS. Ranger made a 20'6" 519VS 1997-2000 that was rated for a 225 (the boat I have.) In 2001 they "rebranded" the 519 to 519VX and shortened it to 19'6" and reduced the HP rating to 200. Now they have the z519 that is 19'6" and rated for a 225 (set up right,I bet that boat would fly for a Ranger.)

I think it's around 15 psi. Maybe a little higher. I'll look next time I have it wound up. This is my 3rd FX. First to were 20 footers. One liked it at 9, the other at 10-11. This one's 21 foot and likes it at 13. At that height, I'm only using about 70% trim and my rooster tail is no higher than the cowling, unless I slow down a bit while turning without trimming down. Then it will shoot a pretty good tail but it comes right back down as soon as I straighten out and get back on the hot foot.

Excuse my ignorance, but can one of you explain the benefits of a hydrolic jackplate vs. standard trim?

Thanks!

It enables you to adjust your engine height for optimum performance in varying conditions. Versus a manual jackplate which would require wrenches to raise and lower your engine. Think low in rough conditions, high in good conditions.

My mistake. You're correct.

My dealer says I'm ok with 10psi, and I watch the digital temp gauge but I dont know how hot is too hot.

Wish I had a hydraulic plate. Adjusting motor height with a manual jackplate sucks. My water pressure gauge never reads less than 20 psi trimmed out and WOT. I run a 20XS Triton with a 25p Fury prop. My top end is around 68 mph with current ambient temps. I wonder, if I could raise the motor some more?????
