Cheapest way to go is to send out your current props and have them cupped, assuming that you have enough RPMs right now. You should be on the high side of the range if you decide to cup, this will make a big difference in mid-range and in how they bite.
Look into Precision props, they make a couple of great props for high HP applications. Turbo is a brand name but they make a fusion 4 that works well as well as a 3 blade TXP that is the shizzziiiitttttt as far as carrying the bow.
Call this guy
Randy 770-318-1136 be kind he has a speach problem and is difficult to understand but knows just about everything there is to know about Yamaha and props
I've bought about 15 props over the last few years (no, I'm not nuts, I've just wanted to optimize several different boat- and engine combinations, and have been able to resell the props at cost).
Of all the dealers I've bought from, only Ken took the time to thoroughly verify that he was selling the exactly right prop for my application. All the others just said "thanks for the order". By double-checking my data, he was able to save me from a trans-atlantic shopping blunder and his recommendation was spot on.
Yes, you can get the props a bit cheaper elsewhere but Ken's service is superb. Now, I just wish he would add Turbo and Yamaha props to his range.
The only props I know of for the F350 other then Yamaha is Powertech.
As Sundancekid said, Putting cup in the existing props seems to do well. I've yet to see someone do it and not like the results.
I've ran powertechs on one F350 boat (31 Capehorn). The guy really liked the way they held the boat so he got them. But on paper, there is not much difference.
The boat was heavily loaded, and he ended up going with 21 pitch props, but I only had a set of 23's to test, so thats what we ran.
31 Capehorn 2008, Twin F350 Yamaha's
Test Conditions.
3 guys
Running into a 10mph wind.
Fuel load of fuel, 290 gal
Tournament load of Fishing gear
Yamaha 23 pitch props. (These props had extra cup added, which reportedly ran a little better then stock)
The main difference was stern lift. The Powertechs held the boat noticebly higher out of the water.
I wasn't on it when he ran in rough water, but it apparently handled great, and thats why he bought the props.
And just to clarify, the owner confirmed he has hit the numbers posted on Capehorns website.
But with a heavy load, obviously the numbers won't be quite as good.
I recently read a sales/information buletin for Yamaha Marine Dealer employees.
It stated:
Yamaha had bought an Indianapolis (Old Turbo) Prop mfg co.
they said that they also plan to release some new F350 props this fall.
that ain't far off.
They also mentioned that a new 4 stroke recent additive oil package had reduced friction considerably.
You can also read about it in the new 2009 Yam brochure ,dated 1 Jul 08..
