Location: minocqua, wi. | i got 53.5 but believe there is 54 there all day long. the 53.5 was second time on the water. tonight i'll spin the 21p Tempest and see what's there, but i agree that it's a no-brainer to be 55+ ... i've been just enjoying the power and connectivity. |

| These motors get better with some age on them. My Opti's always ran better/faster immediatly after break in, and then again after about 50 hours. |

Location: Tomahawk, WI | Ok, just tried Jons 23 Rev 4, all i can say is simply Amazing. Jon and i put in on Minocqua lake and i opened her up not thinking i could turn this prop with my 175 Opti, i was really surprised at the 4 sec. hole shot and the 57.6 gps top end with 5600-5700 rpms. The porposing is gone and i can hold plane speed at 28mph, cornering was fantastic. The boat really cruises nice at about 3800 rpms and 36-37 mph. Also i dropped Jon off at his buddys dock and took it out by myself, and i could not get it any faster, it seemed like it didnt make a difference with him in the boat or not. Just ordered the new prop from Rick at brainerd, should be here in 4-5 days....Yahooooo!!! any body want to buy a 21 pitch tempest plus or a 23 pitch older 4 blade trophy let me know.
Thanks again Jon. |

| weight in the back actually helps mine too...so not surprising to me you couldn't get it going faster solo....when i have a buddy and he sits in the far back mine goes faster than me solo |

Location: minocqua, wi. | that boat absolutely flew!!
flat performance was fantastic ...
i need to get out and really stretch the legs on my boat, i became convinced that my c hull and the vs hulls are totally differently both in how they push and plane but also in weight. after yesterday considering sitting in the chair of a vs with a pro-xs that has even more hp than the opti makes you wonder how truly fast that hull could travel! |

Location: Rhinelander | Wow, sounds like the 23p rev4 works great on your rig. Wonder how the 21p will now preform on my 175efi? Will find out soon.
How much fuel in your front tank? livewells full? Fishing gear loaded in boat also during test runs? |

Location: minocqua, wi. | these motors can max. rpm's on 23's so no reason to pitch down or even consider a 3-blade for that matter unless there is a power-band you would want to hit.
i can see using a 21 for a 150 or at altitude, but i wouldn't even consider a 21 based on what we just showed on the opti |

| Pantlegger, im interested in your 21tempest plus. Call or text 810 three hundred four 1 four 8 thanks. Brad |

| Wow, that's good news. Maybe it's the lower gearing in the 175's vs the 200 Optis. Plus the 690's are lighter than 1890 Tuffy.
Best thing about the Rev 4's is they not only have a good bow lift, but it also lifts the transom too. Less boat in the water equals more speed. That boat get a little wiggly in the back at WOT?
Too bad you ordered a new prop. I have a 23P Rev 4 like new that I ran for about a week. I'd let it go for $300 if anyone is interested.

Location: Iowa | Wow! Now I want to repower. I didn't expect that, but not out of range for what I see with my 150. Good deal. |

Location: MN | Been following this thread loosely. Not disappointed in the hole shot or speed on my 690 vs at all (52 on the gps) with a Merc 150 XRI efi, but that 23p Rev4 sounds intriguing. Would I see as much benefit on my rig with only a 150? |

I don't think our 150's will spin that prop enough. I tried the 21 pitch and was a little low on rpm's. What prop are you running right now, and which hole is you motor mounted on? |

Location: MN | I'm not well versed enough yet to know it off hand, but I think it's a Trophy or Hi 5 (not sure if they are one and the same) 5 blade, not sure of pitch. Boat is up north so can't check. It had a 21p 3 blade before and hole shot sucked. I got the 5 blade from a buddy pretty cheap and it was a world of difference. You are running a 150 also? What are you narrowing your choice down to? |

Location: Tomahawk, WI | Dang-it, Heck of a deal from Shep.....i just paid 575 for mine. I cant give you the exact Rpm i was running at WOT, my tach needle was kinda bobbing around the 5500 and 6000. And yes shep at WOT the boat was squirrly.

| Maybe drop the Motor down one and see if that settles her in the back. Lots of transom lift from the REV 4's. |

I have a High Five 23 pitch on right now. The trophy props are 4 blade. Right now I like the rev. I would like to try a 23 trophy, and a tempest yet just see the differences. Also am going to wait for a 19 pitch rev to come in so I can try it too. I'm not in a huge hurry to switch yet, so I figure I have all summer to figure out which one I am going to get. Might try the 25 pitch high five also. |

| If you like the Rev 4 you should check out this prop http://www.mercuryracing.com/propellers/bravoixs.php I put one on my 1890 Tuffy with 200 Opti and the results where awesome, I gained almost 2mph, better holeshot and some rpms. You have to step up a pitch due to the prop design. They have a blog page that Scott Riechow their prop guru will answer questions http://www.mercuryracing.com/blog/walleye-prop/ |

Location: Iowa | Just got back from the Chip. This was the first time I had the boat out for different conditions. Still had the 5 blade on. 2 guys and gear, it would still blow out all the time. Top speed just over 48. Here is the strange part.....yesterday it hooked up. I figured it must be that the gas tank was down to about 1/2, but it all of a sudden grabbed and never let go again. So I opened it up to see what would happen. Wide open throttle and full trim, handled great, never lost any water pressure, and was moving at 51.3 mph. 2 different gps units showed same speed. Did this happen because the weight of the fuel was no longer pushing the bow down as much, therefore letting the engine settle in and lift the bow better? It really surprised me when it happened. It acted like the rev 4. Any other ideas why it just took off, other than the balance?

Location: Contrarian Island | a few thoughts...
2nd guy placement: was the 2nd person in the boat in the same spot / chair they always sit in ? I have found if the guy in my boat is sitting in the far back vs. say sitting on the front deck extension i get more speed trimmed up.
Gas tank: yes, I think mine definitely runs faster between 1/3 and 2/3rds full...over 2/3rds it is just too much weight... under 1/3 I don't get the "bite" I need....we have 42 gallon tanks i think so you are talking about 250 lbs of weight when full...that's one big dude sitting up on the bow!
Altitude: maybe google altitude of both places you run/ran the boat...if there is for example a 1000 ft difference that can greatly impact HP and performance....
sounds like you should run it at half a tank and leave that prop on tho!

Location: Rhinelander | Update....
Never took it out of the box or tried the 21p Rev 4. After hitting a larger lake to really stretch the motor out was hitting 5800-5900 rpm's with the current Trophy 23p. My bud owns a boat dealership and just brought it back and said I need a Rev 4 23p as the others here recommend. (5800-5900 was by myself, around 5200-5400 with the whole clan in)
The trophy 23p sucks out of the hole and top speeds with full tank of fuel, myself, wife and (2) kids was 49 something. (gps) Livewells were half full too.
This motor was definitely rebuilt at some time, that I knew, along with a new lower unit. The lower unit is some kind of racing deal with exhaust out of the water when fully trimmed and raised on the jack plate. She sounds a ton faster then it is really going. Loud is an understatement.

Location: Iowa | I was thinking the same thing about running half full, but better make sure the gauge works better than it does now. Passenger is always in seat. As for the guy that don't log in........I could care less, this thread is about finding the best all around prop for my boat. If you have nothing to contribute, just go stick your head in the mud at the bottom a lake. If I was wanting to be the fastest I would not have the 150 on it yet. Just writing what is happening with mine so maybe someone else can use the info in the future. Come down and jump in with me or shut up.
