My 2275 GCW has the SPS package. Are the figures indicated above in line with what is to be expected?

Thanks.
 
I get 38 ( gps ) with a 150 Mercury @ aprox 5900 
 
You could change your prop to get more rpm, but I would wait until you have some hours on that new engine
 
I got 39 mph on my 24 spdx yesterday wide open.  I have twin elliptical tubes and a 150 yamaha.
 
You have a 4-blade prop and that's what you'll get, a little less speed and RPM.
 
Also keep in mind that your G is heavier than an S and therefore won't be quite as fast.

Why did the dealer put a 4 blade prop on my boat if a 3 blade is better?
 
I think we need to finally see some pictures of this new boat to better answer your questions! ;)

Probably because that is what he had...?

I got the wrong prop with my boat too. There is apparently a shortage of raw materials going into the Yamaha prop facility, and therefore a shortage of finished goods coming out. It took almost a year for me to get the proper prop for my rig. 

I'd ask here what props others with a G-22xx or similarly sized boat and a 150hp Yamaha outboard, got with their's, and talk to the dealer. Let him know you know that the recommended prop for your setup is _______, and that you're not totally satisfied with the prop they gave you (assuming you are not satisfied...?). 

I don't know that you'll do better than 36mph with a three blade either. I can do 40mph with my GBR 2250 and 200hp. Mine is a bar boat, with heavy counter tops, and a lot of accessories that add a lot of weight. So it's not apples to apples. But knowing you got the correct prop with your boat is maybe something that will ease your mind.

Personally, I prefer a prop that is sized and designed for load, not for speed. You might be in the same boat (pun...hah). Or might not. I went WOT twice last year, both times for kicks and giggles, and just for a short jaunt to see what max speed was. Other than that, I don't ever firewall the throttle. My face looks bad enough when there is NO wind. It just gets worse when my cheeks flap in a 40mph headwind.  So...
 
2015 22 SLX I have gotten 42 MPH, with 2 Elipticals, 2 people and a 1/2 tank of gas. 150 HP Yamaha, wish I had the SS prop.

This is just for Tooncrazy's memory banks for the future. Speeds on the S models are as unrelated to speeds on a G or R as an R is to a Q. And within the models, there are big differences too, based on furniture bars and accessories. All other factors held constant, there are a couple hundred pounds of extra metal between an S and a G. And weight through water is magnified 11x vs weight through air. If you are comparing top speed a, you really have too many variables in hulls, decks and equipment to make a worthwhile comparison. Just so you know.

I bought a Mercury Spit Fire 4-blade prop a couple years ago when I had my 115.  My top speed dropped about 5 MPH, but it put out noticeably more torque and speed when tubing (so under heavy load).  Anyone that's got a 115 and is pulling tubes, I'd recommend you try a Spit Fire and see what you think.  They are not very expensive.  $150, plus or minus.  And it can do double duty as an on-board spare prop.

If there was a single prop that "did it all", there wouldn't be so many to choose from!

Thanks for your comments. When I started this thread I was more interested in finding out if my boat was performing on a par with other boats like mine.
 
I think you are in good shape, but I would still ask about the proper prop for your rig. I don't know what it is, but I have a hunch it is not the one you have. Try them both and decide which you like better.. And keep it.
