Not up on the Hydros really. Are there P5s and then P5xs?

A few years back we tried them and did not like them so they have changed.

The P5 is the pointed ear. The P5X is the rounded ear. You want the P5X on the AT.

Did not have any to try and we went back and forth with Hydro and realy liked there interaction and exchange program so went with them and have realy liked them so far, will be trying a few others this spring as well and will see how they compare in our application.

I ran 27 pitch P5-X"s on a 358 Sonic that I had with great results. When I got the 37 AT I tried them even though they were under pitched and I liked the handling much better that the 32 Pitch Bravo 1 props that came with the boat. I purchased a pair of 29 pitch P5-X's towards the end of last season and I have been getting better numbers with them on flat water test than the Bravo 1's.

What are you seeing with them on Top? How may RPMs are you pulling with the 29s?

I am away from my computer that has the RPMs speed chart on it but on flat brackish fresh water I was running 84 MPH with the 29 P5-X's compared to 82 MPH with the 32 pitch Bravo 1's. I got the boat in August of last year so I have not had a lot of time for testing and getting used to the stepped hull so I am still playing with things. The props are box stock with no labbing or modifications. Pat told me that he had ran the boat in the ocean with the 32 pitch Bravo 1's and acheived a speed of 85 MPH. I would think that salt water and chop would add at least 3 MPH or better to the 84 MPH speed that I had ran on flat fresh water.

The boat handles much better with the P5-X 5 blades and comes out of the hole fairly hard without cavitation problems.

Sounds correct, the hole shot or plane time is much better with the hydros, we would run 85 all loaded up and full of fuel any day, we ran it light load light fuel and perfect chop at 89 mph and 5400 rpm, so 87-89 in light configuration and 85 ish at 5200 rpm with any load.

laszlo01 where do you think you will end up on props when you get things done? What kind of hp and torque #s are you looking for? My engines are turning peak torque of 710 at 4900 and it drops of to 640 at 5900 so I'm thinking I want to prop it as high as I can to stay away from that torque. I think I want to go for 5700 with hp at 710 and tq at 650. I don't plan on running around all day at those rpms but I know the engines won't mind a little speed and I think my drives will thank me for it. Thoughts?

Not sure on the final prop yet, we will be doing some testing with the new setup and will set it up for two conditions, low boost and high boost, should have our dyno numbers by the end of the month and go from there, I will let you know where we end up at once we have it dialed in. Just made our final drive choice and rigging is complete so just waiting on the fianl pieces to get back from whipple and we can get it on the dyno.

Laz, the props should have made it to your door step today. I have the tracking number.....also, I can't remember if I gave you the hub inserts---if they're not in with the props, then let me know....no problem, I have a pair here for you. Thanks again, Mark
