Hey Gents,
Any help would be appreciated to start.
Boat: 2011 Ranger Phantom 16'8"

Engine Weight: 260lbs
Jackplate: Bobs
Tim Tabs: Yes
Current Prop: Power Tech PTR4R16PVM90, 4 blade, 16 pitch and 13.5 diam
Here is the issues:
I am also not so sure I want to go all the way down to a 13 pitch or need to reach 6300 rpm.
Thanks in advance for any hep!

Here is the issues:
- Hole shot is horrible.
- I have to jack the plate half way up, trim it about a 3rd, and get the tabs just right to get 5100 rpm.
- I can't tell you what the top speed is because the speedometer does not read correctly when doing all the above.
- The Yamaha Performance Bulletin for this boat/engine combo uses a Pontoon Prop with 13" pitch and 14" diameter. The performance crushes what I am getting. You can find the performance data here http://www.yamaha-motor.com/assets/..._pntn_rng_168phantom_f70la_2011-06-09_flt.pdf
- I fish in the Lagoon and want hole shot. Speed is secondary but still want to hit 30mph
I am also not so sure I want to go all the way down to a 13 pitch or need to reach 6300 rpm.
Thanks in advance for any hep!
