7mph throughout the rpm range? Does that include top end? Since James use to run 90mph, you boat runs what on top now?
What speeds do you get at 3500, 4000, 4500, and WOT? |

Hi Pat.
I know you know my boat very well. You made it with a very high "X" dimension. With the prop slip being so high, I was going to try some drive spacers but a friend had this set from his old 42 Fountian. They have a 15" diameter witch is smaller than the Maximus. The diffuser is also a little different. I was concerned about the torque they would put on the drives since they are stock Bravo's with 1.5 gears. I ended up buying them because I have been so happy with the performance. They carry the bow very well and at all conditions. I mainly boat on the local lakes in Tennessee and Kentucky. I have been checking the drives and everything has been fine up to this point. I'm going to do a tear down this winter anyways (I'm anal about my stuff). I am still able to spin the 500HP's (modified by James) to 5400 w/ the temp outside at 95. I love the AT. Glad I met James and Reba (GREAT PEOPLE) and was able to buy the boat. Would like to talk to you some time. If they aren't fountain props and are true Hydromotives, I will definitely want to try them out. |
That boat is FAST!!!!! Like Flenner said never porpoised at all, at any speed. Tabs never used them.
Having fun with the AT??? |
Fleener,I would love to talk to you about these props. We will be at the lake in about 24 hrs from right now and will be there for 11 days so lets get together when you get there. Unless we are out on the houseboat we will be in slip 232 at State Dock on a boat name "Long way to go".

The props are stock from Hydromotive. He purchased them new last year. He got a new boat and kept the props, so I got them. I found the numbers from when I was testing in my desk. There are some blanks (my wife was writing the numbers down)
Bravo 3500.....46 4000.....55 4500.....64 5000.....72 Hydro 3500.....52 4000.....62 4500.....? 5000.....79 5500.....85 Since I have had these on, the temp has been in the 90's and humid. Have not really pushed the boat to WOT. Waiting for some cooler air. Look forward to meeting you Boatfreak. We will be getting in on Thursday afternoon (Sept 4) and putting in Friday morning. |

I use the 30" Hydro P5X's (untouched) on my 32' AT...when I added the IMCO -2" shorties the P5X's really made a BIG difference along with the IMCO shorties. It's a whole different acting boat----love it!
