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!
Thanks I talked to Marcus this morning and he was very helpful. He suggested the SWW3r14 or the sww4r13. I also talked with Ranger. The prop I have now was sent with the boat to the dealer. My understanding it took Yamaha a little while to figure out the best prop for engine/boat combo. They are recommending the prop in the performance bulletin now. It is a Pontoon Prop made by Yamaha so I think they are still not there yet. They are going to swap it out for free so I am going to give it a shot. Anything is better than what I got! If it still does not seem right I will try out the SWW props.
You should be able to hit 30mph all day and have a good hole shot. I am running a 2010 phantom with a yami 60 4stk. It came stock with a powertech 3blade prop and seems to have a decent cup, not sure of pitch etc... cause I am at work today, but probably wouldn't work for you cause you have a slightly larger engine. Anyways I have a good holeshot which is important cause I fish the goon alot as well, I can get 30-32 fully loaded or riding solo @ 5800rpm. That is with plate around 3.5" and a very slight trim of the engine..... Also I can run the jack plate full 6" up and not blow out... I also have a friend running a banshee extreme with a F60 and he has great holeshot and still hits around the low 30's, so keep trying props... Great holeshot, and 30 should be no problem with your setup!!
