Just my 2 cents, from a helpful suggestion:

Your boat with a 350 Verado is going to be under pitched at 15. I think your dealer is going way too conservative on outfitting the prop and mounting the motor. Mine did as well, and it took a little bit of an assertive push, back and forth disagreement, and 2 days of trial and error to correct it after the fact when I first got out boat in the water. I’d avoid that process if possible.

Thus, I’d strongly request 17p enertia for that 350 Verado. Second, I also really think that engine mount is going to be too low in the water, resulting in the issues mentioned above (too much drag). Due to boat similarities, I’d request (politely insist ;)) to start out with what Two Tone is switching too above. His changes sound much more apporpriate for that particular boat and motor.

I appreciate the input. I will definitely call my dealer on Monday to discuss this with them. Been using them for many many years and I’m sure they will take this advise as constructive. Thanks

I would love to hear how the test run goes after raising the engine two holes and changing from a 15 pitch to 17 pitch prop. Be curious if it cavitates in tight turns or not and just how it performs overall with the change. Thanks tons
 
I'm following with keen interest as conventional wisdom says I'm seriously under-propped but my performance is still quite good. GCW 2574 with Verado 250, 15.6X13, 40 MPH @ 6400 RPM WOT moderately loaded. Little to no ventilation issues on sharp turns. I'm assuming the larger diameter is making up for some of my pitch deficiencies. That said, should something necessitate replacement of my current prop, I'd most certainly experiment with a 15X15 or possibly 15X17.
 
I would suggest the 15x15.
 
New numbers are in with the prop change and mounting hole change:

  • Boat Model --------- 25 QSB
  • Model Year --------- 2019
  • Toon Package ------ ESP PACKAGE
  • Motor --------------- Mercury Verado 350
  • Performance ------- 50.5 GPS AT 6200RPM
  • Trimmed ------------ 6.4 Degrees
  • Prop -----------------17 Pitch Enteria X 15"
That's about an 8% increase in speed...

And the boat did not porpoise at WOT & fully trimmed...

First test with 15 pitch prop was with my fuel tank at about 20% and just me on the boat...

This test today with the new prop, and engine mount position moved up two was with 3 adults and full tank (56 gallons)...

Pretty stinking impressed right now...

AWESOME! Very similar numbers to what I've been able to get out of my Q25 and Verado 350

How are you able to tell how many degrees the motor is trimmed? Is that a setting in the Merc smart gauges? Mine show's Trim #'s but not in 10's of degrees

There’s a setting in the setup of the gauges that allows you to change it...

That is great information. My dealer has set up our 2019 25QX with A 350 Verado w/ a 15 pitch Enertia. We will put it in the water in the spring to see how it runs. My guess is we will have to move to a 16 or 17 pitch. He also has mounted the motor as long as it will go. Thanks

Question. If you ordered the Simrad, did you get the G05 or G07. My 2019 QX25 came with the G05. Maybe because it was an early bulid??
 
That is my understanding too, which is a real shame. I would LOVE for the G07 to fit in the dash space so as to enjoy a bigger and easier to view screen. Oh well, I still really like our G05.

I believe the cut out in the dash to the far right limits the simrad size to the 5”.

Keith, I don’t think the 2019 models will allow for a 7” touchscreen. I’m thinking it’s probably an economic decision by Bennington as they probably have a warehouse full of the currently configured dash set ups. A 7” would be nice. It offers much more utility for not much more cost, in my opinion.
I guess we will have to live with the GO5
 
Thanks all for the input. Big difference between the G05 vs G07. Oh well. I just looked at the 2019 online brochure and it is not an option.
 
New Bennington Arrived:
  • Boat Model --------- 25 QSBW
  • Model Year --------- 2019
  • Toon Package ------ ESP PACKAGE
  • Motor --------------- Yamaha 350
  • Performance ------- 48 GPS AT 5800RPM
  • Prop ------------------15 Pitch X 16 1/4" Diameter Saltwater Series XL SDS
Light breeze, choppy water, full tank and two on board.

Awesome! Congratulations on the arrival of that beautiful boat and being able to put it through its paces.

We're starting this thread to collect everyone's specs in one place. That way, anyone wanting to know how the different options will affect their own boat just can look in one spot to see everyone else's real world experiences.

Just hit the reply button to this post, which quotes the format, and edit it to fit your specs. Simple and easy.

Make sure you get in the small details like the size of your pontoons, do they have strakes, the brand, model name and HP; that sort of thing. If you happen to have a specialized option like the ESP or Dual Elliptical setup, or perhaps are running a jack plate, mention that too.

​



Oh, almost forgot... Let's try and keep this thread "single purpose". If you are reading the thread and realize you have a particular comment or question for someone in regards to their specs & numbers, just start a thread in the forum and make sure to include the person's Online Name in the thread title so that they know you wanted to ask them something.

​

That's about it. Have at it! B)

Yes, the boat is underpropped. Dealer switched to this prop from a 15x15 4-blade stainless prop (boat was overpropped). Waiting for a new 14.5x15 prop.
