Back in 2011 I had my props done by Chuck Gray from Pitch Perfect Propellers in Stanford. He told me at the time that he was going to be moving from his space in Stanford as the marina was closing for condo construction. Does anyone know if he is still in business and how to contact him. The e-mail I had does not work, and the phone just has a generic answering message. I was very pleased with his work at the time.

The alternative is to ask who is suggested as a good prop shop in the area. The Prop Scan web-site shows the closest shops being in Newport RI or South Jersey. There must be a quality shop in the area. Thanks…..
 
I called you earlier just for that :-) I wanted to know if you were going to do something, any way I believe either starry night or hogan used him and have his number.
 
The last # I have for him is 845 430 3763
 
Bill, Chuck is operating his business in Hopewell Junction now.
 
Jimmy is going to remove the props and then Chuck will pick them up. Should be in the next few weeks. I think however that Sea Ray sent this boat out with the wrong props on it. They are 24 x 27 cupped and everything I see on the same boat is a 26 x 27 cupped. Time will tell...

Were you able to make your max RPM speed per the motor specs? That will determine if you have the correct prop size, not just a number.

Did you make your max RPM's with full fuel and fuel water and all of your gear and people on board?

If you cannot make the RPM's then you are overloading the motors at any on-plane speed.
 
Yes it is hitting the correct RPM's but the fuel burn (GPH) is a lot higher than other 44 S/B's. Also I am not getting the same cruise speed at the "ideal" RPM as the other boats. Bottom line is I burn more fuel and go slower, not something I like.... Other than that this boat is fantastic...
 
The other 44's have the same props with different a pitch?

If you are making your RPM's then there isn't much you can do about changing the pitch. You always need to hit that Max recommended RPM, I like to go over that number by at least 50 rpm's, this way there is no chance I am overloading.

I wonder if the other 44's are making their max rpms?

IF you are 2" smaller than the same boat and make the RPM's that make we wonder why or if the other boats are making max rpm. Same power?
 
The other 2007 44 has the same power (500's) while the 2005 has slightly smaller (480's). Those other 2 run at about the same numbers I believe. I am not full of knowledge on prop or cup sizes, but I do know GPH/MPH, and I want to correct that if I can.
 
RPM is the crucial number. For my Cummins, the recommendation is to hit 150 over WOT - otherwise, the engines are overloaded.
 
You can make RPMs with the wrong size props it could be undersized and over pitched still make RPMs and run un-efficiently. I drove Bill's boat home from Delaware with the owner of one of the other boats. It was clear that the boat goes slower then the other boats at the same RPMs and burns more fuel to achieve the same speed as the others. The motors run like tops there seems to be only one logical answer the props are either wrong or not configured correctly. This is a great boat and I'm sure it is a simply fix! It's drives like a dream I only wish Bill could have been there for this ride.
 
Bill wishes that as well, but he is very blessed to have great friends who help out when needed..... !!!!
 
Glad to have been there, hope this type of help is never needed again!
 
Bill, Just FYI...
My 2005 Searay 420 Sedan Bridge has 26 x 26 nibral 4 blade cups with 480 CE Cummins.
This Prop/ Engine combo pretty much runs dead on to the boat test number's below...

RPM MPH Knots. Total GPH. MPG

1000 9.3 8.1 4.2 2.21
1250 10.9 9.4 8 1.36
1500 12.4 10.8 12 1.04
1750 16.9 14.7 18.2 .93
2000. 22 19.1 25.2 .87
2250 27.3 23.7 31.6 .87
2500 31.5 27.3 40.8 .77
