Hey Gents, Any help would be appreciated to start. Boat: 2011 Ranger Phantom 16'8" Boat Weight: 650lbs Engine: Yamaha F70 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: 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. Additional Info: 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 My Needs: 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!
