Running Hydromotive 27 Pitch 5 blades and very little tab is required at slower speeds to keep the bow down. no tab required at higher speeds. I ran 82 Saturday afternoon in fresh water.

Re: Prop selection for 358 with 500efi's
 

Hi Guys I Have A 35' Boat With Hp500s ,brovo1 Drives And 28' Props Lab Finished The Boat Run 80mph At 5600rpm. The Way I Have It Set Up Is The Props Rotating Inward. (this Holds Down The Bow) The Problem That Most Of Seam To Be Talking About. The Easy Way To Try If This Works For You Is To Swap Props From One Drive To The Other And Then You Would Have To Run The Boat In Reverse For This Test. Good Luck I Hope Works

I have a 03 with 525's and am running lab28 b-1 's and
I have the standard outdrive settings. yesterday 77gps 1/4 tank two on board.
This thing also sucks fuel I would love to see better fuel mileage and top end .
I am now on the limiters at 77gps trimmed up no tab.
Are the Hydromotives Labbed?
Thanks for help

Re: Prop selection for 358 with 500efi's
 

Roadrunner the Hydromotive Props are not labbed. The difference between the Hydromotives and the Bravo 1 props is prop efficiency.I am getting a slip factor of 7% with the hydromotive P-5's and I was getting a slip factor of 19% with the standard 30 Bravo's and the 30 labbed props were even worse as far as efficiency. I am turning around 5200 RPM's at 82 MPH GPS with the Hydromtives P-5 27 pitch. Handling and fuel economy are also much improved with the P-5's.

VIPER7 Thanks for the reply . It sounds like the way to go . What do you think about labbing the hydromotive p-5 Also where did you get your props and how much did you pay for them? Thanks for your help! When your boat was running 82gps what kind of a load were you carrying ?
Thanks

Has anyone tried a pair of the Mercury Maximus 5-blade ?

Re: Prop selection for 358 with 500efi's
 

Roadrunner, I got the Hydromotive P-5X Props from Matt at Throttle UP and he worked with me as I tried two different pitches from him. As for labbing the props I have not tried any of these props.The standard props put me in the RPM range where I wanted to be and the standard props are a lot stronger and not near as subject to damage and breakage as the labs. I feel sure that Matt could give you some info from Throttle UP. When I was running 82 I had 5 people in the boat and a little over a half a tank in the fuel tanks.
