37 Quad Step #6's In Or Out
 

02 Quad Step with 1100's Staggered currently spinning in, 17x33 Merc 5 blades, Boat is a hand full over 110, Tabs help a lot but scrub #'s. Any set up info would be appriciated, I think there was only 4 of these boats built, Tech at OL says the boat should run well into the 120's, I aint buying it.

i am running #5's and i went from spinning in to spinning out and i didnt notice any difference. I was trying to solve the same problem once i hit 90mph the boat starts to gallop and i still have plenty of more power i have hit 103mph once but its dangerous. Once you add tab the boat is find but slows the boat way down. swapping the drives did nothing for me.

Have you tried a smaller diameter wheel??

Have one...boat has enough power to run 120 but can't get it past 110 without a near death experience.... One hell of a boat up to 110 though.

P.S. I've been told that a smaller diameter prop and 1" spacers in the drive should solve the problem, but I don't feel like spending the time and $$ for a "should fix"

Bret at B-Blades feels the smaller wheel and dropping the drives will help also, I'm thinking that would be the first step, OL tells me they can change the angle of the steps and solve the problem as well, And yes it's all fun and games until you get near 110, any info on the 42 hulls? How do they run upstairs? That's what I'm looking at next.

I've heard the some thing on the quad step 37's from a very reliable source. I think the 42's are good up until the upper teens, then after 120 they get loose and slippery. I know for a fact that the 42's are dead stable at 110.

I would be very happy to run 120 in a V with a loaded cabin, looking to sell the boat and don't want to throw another 10K at it to get there, sounds like Diameter and spacer's are the way to go, I'm always willing to give up top end #'s to pull hard.

i also added a one inch spacer and saw no difference, and i also went from a 32x18inch diameter prop to a 32x17.5inch and still no difference just harder to get off plane.

Are you running a Quad or single step hull?

By looking at his profile it's a single step. All the quads were after or in 2002 I believe. There's the one in Jersey (Joe D), yours, Maine (Tazz) and the purple one that was just wrecked.

Purple one wrecked? Hadn't heard, what happened?

im running single step

facts
 

I used to own let's rock and it would run 116-7 with 4 blades without any issues. the most it needed was a little right tab.

you need to test in calm water and get comfortable at speed then start triming to max out

2002 is correct, I would really like to know happened to the purple one and hope no one was hurt.

Any seat time in a Quad Step? Not sure how different they are from a single but I'm sure it is quit a bit. I was running 17.5 33 4 blades and it was about the same, I think the boat got a little better with the 5 blades, both need a ton of tab around 110.

The single step boats will actually handle better above 110 than the quadstep, they just need more power to get there.

Thats what I'm thinking! So what is the answer to the Quad step bottom issues, OL and Activator both claim they can modify the hull, Very happy with the boat other wise.

I don't think there is an answer. 110 is it, when I want to go faster I get in my cat :D

Links are you doing the poker run this coming weekend. I saw your ride at Nauti goose this weekend . Looking good.
If you want to run faster than 110 safety buy a fountain:cool-smiley-011:

Here is the link to the "Purple 37 OL" that crashed...http://www.cooperss.com/1-1-24749-Outerlimits-Stiletto, have not heard about what happend to the driver, or passengers. Does anyone have any more info.??

here is what happened to the other quad step 37

Not trying to cause any trouble here, but one of my best friends was the 3rd owner of Lets Rock and we thought it was very ill handling. Difficult to get on plane, Would sometimes porpus around 90 ish. And very light about 110. These are the reasons he sold the boat. It felt as if it had a very high X-dimension. It was very fast however, especially for a 900SC boat. Again not trying to cause trouble, just trying to give some info that might help others.

Does that make my boat worth more or less? Good to hear no one was hurt! Hope his insurance was paid up.

Lets rock was a single step i thought?

My boat handles better than any boat I have been in up to 110, (Big Cats excluded) I almost wish it didn't have the power to go faster but it does and I want to use it, One guy said you gotta drive through it! Thats BS. Some one out there has the answer.

Yes it was a single step, however I just didn't want you to get the impression yours was the only one that had issues. I did ride once in a quadstep 37, and it rode much better that the single step. There were 6 guys on board with gear and a full tank and it came on plan very easily and rode great, very flat. We ran from Sunshine Key to Key West never below 100 and up to about 110.

joe D's 37' quad step,Manahawkin -NJ

I dont like to crawl into my cabin and have the windshield at my waste, And I'm 5'7"! Other than that nothing bad to say, Just aint a Fountain guy

OK JoeD, Whats the deal with the Quad steps??

From reading the classifieds my 37'QUAD seems to have the smallest engine pkg, most have twin 1000's or better-- where mine are twin 675 Eickert pkg's with Whipple Intercoolers,the story of chine walking is also evident in my situation.

I believe there are about 8- 37' quads out there.

Joe D what speed are you getting out of her. Nice ride

Bravos or 6's? What speed does your hull get out of shape?

Joe has number 6's 17.5 x33 4 blades. Motors actually make 830hp. Intercooled supercharged 540 with 871s.

Motors are staggered set up.

I know the boat pulls hard with those props! Is he spinning in or out? Top speed with what settings?? Are you guys doing Rock The Bay this weekend?

My one motor was just rebuilt at JC Performance along with Richie ZUL doing the dyno work. The motor hit 817 hpwith almost 800 pds of torque(broke earlier this summer)--- we also tuned the EFI box on the 2nd motor(not rebuilt) to match ,----earlier this year I purchased 2 -17.5x33 x4bl props from a guy down the Chesapeake that was running them on his Quad step with 1000/1100 hp motors that I believe was turning them at 6000/6200 rpm or so and was hitting around 115mph------since my new motor has only been in a week now with just a short run on it I havent really brought it up to top speed yet ---the boats best speed prior to this year with 17x33x4bl props with a rev limiter set low at 5400 did 103mph,-----with the slightly larger props and a new rev limit set for 5700 rpm along with a new tune up in the EFI's I will be wishful for 108 mph.

The gentleman that sold me the props did invite me to leave my boat at his dock for "Rock the Bay" but unfortunatly my wife and I are sick this week with the flu so we will probably just stay in Nj. Please thank him for the invite

You got my old props, Theres only one Quad step on the Chesapeake! Let me know how you make out.

Yup I figured they were yours,how are you making out with the 5 blades he told me about.

What was your buddys name?
What size and pitch did he tell me you were testing and what were the before and after numbers ? [email protected]

In response to your question about the 42, I went for a ride in a 42 with 1075's and the boat was solid as a rock at 112 with 6 people. The boat probably had more in it we were running out of room. I have a lot of first hand experience with the boat you have, it was my Dads. I can attest to it being a handfull, but for us it seemed over 105. The boat did a stern to bow lope an then a pretty violent chine walk. He did drive it 112 on gps once, but it was all over the place. One of the fastest v-hulls I have been in to that speed though, which is hard to believe considering how big those 37's are.

He talked to Mike a bunch of times and he was willing to help him with the boat, but he would have to take it to RI. That may be your best solution.
