Location: N Illinois | Running a 2002 ranger 619. Had to repower do to motor issues.
Old motor, 2002 200 hp mercury optimax. When new could reach gps speeds of 52 mph at 5500 rpm. Last couple of years getting 48-50 mph at 5500 rpms. Running a tempest prop, 21 pitch.
New motor. 200 hp Yamaha vmax SHO four stroke. After break in period opened her up. Maxing out at 5200 to 5300 rpms. Hole shot excellent. Top speed gps is 55 mph. Currently running a Yamaha vmax prop with pitch of 22.
Speed is up, but rpms down. Mid range seems good. Question is do I have the right prop with these numbers?
Thanks in advance. |
