Maximus vs. hydro px5
 

How do the two compare? I tried the Hydro with poor results. Wondering it the Merc. prop is diff.

Re: Maximus vs. hydro px5
 

How about some specifics? What were you running before and how did the Hydro perform?

Re: Maximus vs. hydro px5
 

Close friend has a Y2K also, he has been running the Merc Maximus 5b. 496 Mag HO Whipple, runs 80+, he swears by the prop. Believe he cut diffuser off as well. Contact your builder tell him you need to get in touch with Cary with the black hull from Syracuse N.Y. or I could PM his number to you, let me know. He is a good guy and fussy on his set up, might be able to help you. BTW the Y2K is a very impressive hull.

Re: Maximus vs. hydro px5
 

I just added a whipple this winter. So far only a 5 mph gain top end but big jump in cruise. Just curious if the extra torque would get even higher cruise and maybe help up top.

Re: Maximus vs. hydro px5
 

I added whipples too and tried my 5 blades and got about 13 mph with them.tried a 32 stock 4 blade and got about 20 mph.5 blades where great to get on plane and increase in the cruise area.Top speed they didn't help.

Re: Maximus vs. hydro px5
 

FYI ---- Cary gained 10+ wtih his install. Prop was part of it.

Re: Maximus vs. hydro px5
 

They definitely have different personalities. The Maximus has one advantage in that the prop is bigger at 15 5/8" diameter allowing for more options in the mods. and application set ups. However, the P5-X can run great right out of the box on the correct boat and drive height.

Both props are awesome on the correct application.

Re: Maximus vs. hydro px5
 

Superbabi is also running a Maximus on his Y2K.
I would bet the larger diameter would realy help with your high X-dim.

Re: Maximus vs. hydro px5
 

I think you first need to spin the prop in the right direction :drink:
Dang lefties.

Call Bret, he will get you set up correctly. Maybe we could get a bulk rate on shipping :p :chimp:

Re: Maximus vs. hydro px5
 

we just about finished a whipple recently. running hydromotives on a 38 fountain. saw about 14 mph so far. going to start looking for another 3 or 4 with props and maybe drive heights. if you need to try something I have different props around and i am on the hudson.

Re: Maximus vs. hydro px5
 

Try Herings

Re: Maximus vs. hydro px5
 

JimG,

Thanks for the offer! Where on the Hudson are you. We launch out of Stoney Point.

Re: Maximus vs. hydro px5
 

I have a friend that is asking the exact same question. The boat wants bow lift. It has a very high X and the drives are close together, (like a staggerd setup). It is a 35 Nordic step hull.
I think he would like to try a few different props, or buy some used ones in the 30-32 pitch range. May also be looking for used Herrings?

Re: Maximus vs. hydro px5
 

Hey Gordo,

The Hydro P5-X runs well on the Nordic 35. I have a few running them out there. Call me anytime.

Re: Maximus vs. hydro px5
 

Julie,
I'll have the customer call you direct. You're gonna love the boat these are going on... ;)

Re: Maximus vs. hydro px5
 

Sounds great Gordo, Thank you! I will help them in any way that I can.

Re: Maximus vs. hydro px5
 

I thought I might bring this thread back to the top.

This past Sunday OH-Zone and I got out on the water to do some prop testing.
I have a 1997 24' Super straight V, 502Mag, Bravo drive with the prop shaft 5" below the keel.
OH-Zone's boat is a 2006 30' Super, 525EFI, Bravo XR with ITS.

Anyway, my boat ran about 75mph @ 4800rpm with a stock 28p Bravo 1, but was real sensitive to trim; the "sweet spot" was small.
Now with my BBlades modified 28p B1 I have seen a best of 77mph at 4900rpm and the boat is less sensitive to trim. I'm a happy boater!

Then I had a chance to run OH-Zone's 5 blade Hydro that is a 25p P5-X modified to 25.6". I must say that prop is awesome!
It did feel like the boat had more stern lift but she still ran vary stable. The top speed was 75 @ 5100+rpm, I would bet that if the prop had been a true 26p and my engine ran a little less rpm, the top speed would have been the same as with my modified B1.

OH-Zone found that the P5-X was the fastest and best handling prop on his boat.

To my question, would my little 24' run well with a Merc Maximus?
I know, try it you might like it... :D

PE, have you tried a 5 blade on your boat again?

Re: Maximus vs. hydro px5
 

Pat,
Haven't had the chance to try a 5 blade. What was your cruise speed with the 5 blade?? I'm interested in the Maximus to see how much I gain at cruise. I cruise between 3700 and 4700. WOT are for short bursts. Sure top end is what everyone is looking for, but I'm willing to sacrifice a few up top to gain down low.

Besides, I can always carry a 4 blade for when there is a need for top end.

Re: Maximus vs. hydro px5
 

We didn't do much cruising... :D
With the 25.6p P5-X, 4000rpm was about 58mph.
With my 28p B1, 4000rpm was about 61mph.
Again if the P5-X had been a 26p, I believe the numbers would have been vary similar to the B1. On my boat anyway...

Re: Maximus vs. hydro px5
 

Gordo,

I am willing to bet that this is the Nordic with the Imco gear splitter and single quad rotor. Am I right? Do I win a prize :drink:

Re: Maximus vs. hydro px5
 

Dat's Da One !!
I'd offer a boobie-prize, as soon as I can find a formidable sponsor to donate... ;)

Re: Maximus vs. hydro px5
 

Gordo,

I am really intrigued by the IMCO gear splitter. I have thought about a gear-splitter for a 32-34 foot boat single engine boat with about 900HP. Unlike your friend's Nordic, I would like a full cabin. I have only seen this in the ski-boat and that Nordic. Looking for un-biased input on the pros and cons. Have you ridden in the boat? Can you shift each drive independently? I would think so. I love the idea of the low CG, high X-dim, and 19" centerline between the drives. Any idea of the price.
