10 mph gain @ 3500 wow, most guys I boat with will have to keep it to the pins just to keep up to your cruise speed. :eek: - I'm going to have to look into a set of those -

ran a disappointing 83.5 this morning - running a bit fat - engine builder is going to come & dial it in :rolleyes: hopefully.

My 96 35' with HP 500's runs 79-80 on gps at 5000 rpm with stock Hydro 27's spinning in.

Just ordered 32 pitch labbed Maximus Props. Merc Racing says I will see 3-4 MPH gain on top end 7-10 MPH on cruise. Alot of dough ($1500 each) but if it works it will be worth every penny.

I find these #'s hard to swollow - I have two new 625hp motors(on the dyno) in the same hull, same drive ratio (tried the same props) & I'm almost 10 mph slower with 100hp more per side :( WHATS GIVES??

The 35 Single step with 525sc's we HAD DID 84mph.
That was with 1 person and full load of fuel.
Great boat with alot of mid range punch !

Are you still running the labbed 28" Bravo 1's? 18% slip is a bunch.

I'm a fan of Hydro props, especially on a Fountain. Bravo props tend to be a bow-lifting prop, and Fountains carry their bow well on their own. The Hydro (specifically the Quad IV) is a stern-lifting prop, so the combo of the Fountain carrying it's own bow, plus the Hydro lifting the stern makes the whole boat run "looser' in the water, less wetted surface, more speed.

I'd try a set of stock 28" Quad IV's. If you like how they feel, spend the extra $$ to fine tune them with labbing or extra pitch. I think the rule of thumb is to shoot for 10-12% slip. Matt and Julie at Throttle-Up are whizzes with props, and I highly recommend their work for your fine tuning.

I'm still not convinced spinning "in" is worth what you give up overall. I've not heard of much more gain than 1mph or so, plus handling goes to chit, more so around the docks. I spin mine "out", race it, poker run it, play on it with my lady, and have no complaints how it handles.

10-meter with no steps, 83+change, with 525hp, 28" Hydros.

Cheers,
Brian

I'd like to try a set of Hydros - (before I waste more money) - my best run was with 32 pitch bravos so far.

Re: 35 (Single step) owners -speed#'s
 
32" Bravos... you might try a set of 30" Hydros, and tweek from there.

I'm itching to see my numbers this year, too. I've bumped up my motors to 600+, so prop adjustments are in order. I'm going to run my 28's and get a baseline, and go from there.

Cheers,
Brian

I have been viewing all the specs in this thread and found that my 35 with a single step with 525SC's runs the same as everyone else. But it also has ext boxes and I thought they should give you 3 to 5 mph . The motors are brand new and the drives are mounted high, I can not trim the drives all the way up with out them trying to come thruogh the swim platform. This summer I have to put some limiters in the trim indicators. Every one tells me it should be running faster and something is wrong. I know the boat is tuned to a T. jetting is right on , timing is at factory spec 35 at 4000. botttom is clean. I guess it is as fast as it can be but fine with me. It is one nice boat.

I was hoping for more top end as well - I'm run'in stock drives & no boxes - when I spoke with Throttle up last week, after reviewing my #'s they suggested 1 spacers to lower my drives thus reducing my slip #. I'm kind of getting frustrated - so far my best run was 83 - even after having my engine builder come & tune, jet & time them in the boat. oh well

I have ext boxes on my 35 also, they do not help as much on a notched transom like a Fountain, where they show there colors is on a flat transom boat

P4-those are great numbers for a non step! did your x dimension change when you swiched to the Konrads???........signed- still dont have steps :D

Thanks, it's taken some tweeking to get it here.

Konrads work out almost 2" shorter (1.68") than a TRS. I started out with a 1" spacer, then a 1/2" spacer, then took them out altogether. Just kept getting faster. Throttle-Up tuned up a nice set of wheels for me, too.

I considered putting a set of Konrad boxes on, but I haven't heard anything definitive about how much it would help. Plus, I wasn't jazzed about jacking up the motors to make them work. They're doing the engineering work on a "shortie" lower, so I might give them a try once they're out.

She's also pretty light in the cabin. Just some padding here and there. Everything else is up in the attic in the garage.

Cheers,
Brian

From what I understand - the newer 35X's 01-05 have a higher X dim. as compared to '97-'99 models - this would explain the Top Speed differences. Is anyone running -2" shorties on a '97-99 model??

not to heavy - twin style - it's back on now - I ran it like that to make it easier to check for leaks & potential problems after my rebuilds.

97 35' 600hp, -2" imco shortie's, 28 lab hydro's, 89.6 mph at 5600 rpm's, on a cool september day with 2' chop, by myself. On a normal day I run 86 to 87 depending on fuel and passengers. I never ran good with Bravo's.

Welcome to the board D.F those are solid #'s - kind of what I was hope'in for :mad: I sure would like to try a set of shorties.

I have owned a 1990 35 lightning since new original factory bravo's 502's carbs 450hp? currently run 72 mph to 75 low on fuel one person. I'm adding whipples and efi. What can I hope for for speed and hp on low boost ie. 4 lbs on this old hull bottom?

Marginmn 05-26-2005 12:14 PM

Re: 35 (Single step) owners -speed#'s
 
Without a step I would guess mid to upper 80's.

What's your target HP and rpm with upgrades? What props are you running?

I've got an older 10-Meter (basically same hull as yours) and ran lower 80's last year with 509's/525hp @5200 rpm, 28p Hydro Quad IV's. Take a look above in this post for details.

Welcome to the Fountain board!

Re: 35 (Single step) owners -speed#'s
 
target horsepower is 625hp with mild boost. Props will have to be suggested as I only have original 3 blade mirage.

Marginmn 05-27-2005 10:06 AM

Re: 35 (Single step) owners -speed#'s
 
If you are only going to push 625hp then I would say lower 80's.

Ran-Dom 32 05-27-2005 10:22 AM

Re: 35 (Single step) owners -speed#'s
 
due the lower X-Dim. on the older hull - you should look into -2 shorties to really benefit from the HP gain.

Re: 35 (Single step) owners -speed#'s
 
does anyone know how the new 35 ex with 525efi's comes out of the water? after owning a blower motor boat I would think any thing else would be a pig. We had a 27 fountain with a hp500 and thought that was a hot boat . but after running blowers and going back to the 27 it took for ever to get on plain. I am so pleased with my 35 it gets on plane right now. No matter how many people are in the boat. But I would consider a new 35 with 525s if it will run 90 and not be a pig getting on plain.

Marginmn 05-31-2005 09:22 AM

Re: 35 (Single step) owners -speed#'s
 
My 35 ex with hp 500's took about 2 seconds to get on plane. The X was stock from the factory.

Very interesting thread!

Rebel_Heart 06-12-2007 10:53 PM

Any updates on the 35' single step in the last couple of years? I am in the process of trying different props since I increased hp and added -2" Imcos. I will trying 32 Bravos the next time out to get rpms.
Any other props to try? Sounds like some don't like the Bravos because the Fountains already have good bow lift.

Reb,

What power are you running? Sounds like 28" labbed hydros might be worth a shot. I run 30" labbed Bravos...same boat, same set-up as yours.

Rebel_Heart 06-13-2007 08:04 PM

I did have the 502s, but since they have become 540s. We dynoed last summer at 710hp @5800. I was just wondering if there are 5 blades that would have the top end as a labbed Bravo would have? I hate to go down the road of having everything labbed to make the call. Right now, I have been renting props from Bblades.

What is their program on trying props? What about Throttle up's? I know the guy I bought my boat from had BBlades do his...

Rebel_Heart 06-14-2007 02:40 PM

Bblades is $20 for 15 days. You pay the shipping both ways. Not a bad deal when you are unsure of what prop is best. I haven't worked with Throtte Up.

Slumpbuster 07-16-2007 10:52 PM

Twin Step but here's my input. A couple weeks ago, I was in the red 02' 35 lightning just listed for sale.

http://www.offshoreonlyclassifieds.c...o17425-en.html

It was reading just over 85+mph with 2 people, 2 full tanks, smooth water with more trim and tabs to go. small lake. this was on the speedo. sorry no GPS. it has 500's and bravos. not sure about props or ratio's.

will update my profile when i get time.
