Need help with setup.
1993 VLX200, 1996 Merc. 150 XR6, 3 1/2" below pad, 9" jack plate

Boat came with a 13 1/4 x 25" 4 blade Turbo: 5600 rpm 64mph had to trim all the way up and water psi at 12. After 60, boat gets chine and then uncontrollable.

Tried a 14 5/8 x 23" Tempest: 61mph, 5200rpm, water psi 16
Boat gets real sloppy after that, but it didn't feel
like I could have got much more speed.
