Formula 3??

[Mondorally]

What's the scoop? I've seen a few mentions of the "new" Formula 3 class. The only thing I found was the rules to the Worlds stating it was for 150hp outboards. Are we talking about the same class here in the States?

5.37 Formula III Rules:​

Engines

: 150 HP Maximum Horsepower – about 111,85Kw. (with 5% tolerance) at the

propeller shaft
The Formula III boats, must comply with all the specifications as per Rule 5, from point
5.01 to 5.35, as shown in the current EAME Racing Rule Book, with only the following​

modifications allowed:

a) Minimum Length of the hull 18ft or 5.48 metres.
b) This class is for ​

​

Single outboards only.

c) Seating Pilot and Observer side-by-side. Backward facing Observer seat can
be positioned aft of drivers seat.
d) Standard Recreational outboard engines of 2 stroke, direct injection, or 4
stroke. Not racing or high performance. (See chart in this bulletin)
e) Maximum power of 150 HP/111,85Kw, measured at the propeller shaft as per
ICOMIA specifications.
f) Standard Manufacturer’s Exhaust, under water level
g) Only allowed to change the propeller pitch
h) Steering. Dual Cable or reliable Hydraulic Steering System
i) Ballast tank allowed
j) Bracket, if fitted, adjustable only by hand, not during navigation
k) Boat construction: Normal materials like on the recreational boats. Not
permitted other materials used for racing like carbon fiber, etc.​

l) All engines must have operational forward, neutral and reverse gears.

Thanks!

Hmm,, ballast tank with 150 hp. Hard to imagine a stock 150 being a "race" engine with no ballast.

Too bad it's not 175 hp,, got a spare powerhead here that I plan to rebuild this winter for mine.

 

[RiverDave]

I noticed they didn't specify whether or not the boat could be a tunnel or a V as well.

I'm wondering though with that ltd horsepower if it would even be an advantage to run a tunnel?

RD

 

[Flying_Lavey]

I noticed it said the power was measured at the prop shaft. Do they dyno the engine for each boat?

Just wondering cause at one point in the 80's Merc changed their rating from rating it at the flywheel to at the prop shaft and the 200's that were rated at the flywheel at 200 where actually a bit less at the prop shaft.

 

[River Lynchmob]

It can be any kind of hull you want but i think you would want something like a Lab...the engine has to be sealed by an approved mechanic and they wont pull it appart. If it's sealed they can pull it down on the spot on your dime...That's how i've seen it in Oz

 

[Mondorally]

So does anyone plan on running or know of anyone that plans on running Formula III? Any idea when the official NWSRA rules will be updated?

I was soooo close to fitting in those rules too!! But my boat is 18'6" and I have a 200 on it.

 

[RiverDave]

It's 18' minimum, so the boat is fine.. The 200 is your problem.

Ahh.... I mis-read that. well, I would LOVE to find out what exactly are the differences between a 200 and a 150 besides the power output and the number on the side cause I dont have any serial numbers on my motor and would love, if for not other reason, to verify that it is a 200.

 

[RiverDave]

Are you thinking about buildign a boat Justin?

RD

 

[Crazyhippy]

I'm not sure F3 is going to help much... F2 was supposed to be a cheap way into the sport, but to be in the hunt requires a specialized boat which isn't cheap.:grumble:

Hopefully F3 stays low buck. If it does, an old low profile ski boat, and a old carbed 150 could be running under maybe 5K (7K is easy). Put a bolt in backseat together, and i've got my training boat:skull

Seems like an interesting class but I'm wondering if there is going to be enough interest in it. Formula 2 seems real popular and I wonder if enough people will sign up for Formula III to make it fun.

When I was rally racing I had a Group 2 car. As far as classes went, it was the 2nd slowest out of the 5 or so classes. But it was always the biggest in terms of entries and competition, not to mention most of the folks were grass roots out there for the fun of it.

I'm wondering what is (or will be) the equivelant in ski racing....

I am saying 150 HP with a ballast tank would be an awful slow ride

The displacement is different between the 150 (122 cu in) and the larger 175 and 200 hp models which are the same 153 cu in. Bore of the 150 is 3.125",, and the 175 and 200 are both 3.500". Crankshaft stroke is listed as the same for all 3.

So, I guess for the price of a head gasket, you can check yours out?

 

[Firecracker]

Well if they have any Worlds events in Belgium again this won't be a problem... LOL I may be wrong here, but I believe there is a 60 mph speed limit on the class as well.

Keeping it affordable is the main idae about it, especially here in the states. With the HP limit there really isn't too much you can do to go wild.

It is a great way for new skiers to ski in a competitive class, and come up the ranks to F2, then Open. And with consideration of being in the 2011 worlds, this is huge.

This year was the largest turnout in the history of worlds with a total of 78 teams entered through the juniors and up through the ranks in men's and women's divisions. Not too shabby if you ask me. You add F3 and you have serious growth, that almost the average Joe can afford. The it truly does become a skiers race, because all of the boats are so evenly matched.

I am very excited about this class, and sure wish it was around when I was at that level!

 

[Crazyhippy]

If it gets to the point that you need a purpose built boat to be competitive, it will be too expensive.

It will also die then, because the difference between a 40K F3 boat and a 50K F2 boat isn't very big...

This one is on the high end. I know of one Hallett F2 boat that sold last year for 20K with a 2.5. A couple other competitive boats have sold in the $30K-$40K range the last couple years. Obviously they are all used. F2 is still a great class that is cheaper to run.

Hmmnn. Interesting to know. Are most of the boats sold word of mouth? Any places besides nwsra.net to look for boats for sale?

 

[Crazyhippy]

That Bernico is BADASS!!! Was in the lobby of the LA boat show last year. Wheeler snapped some pics of it @ the pudingstone dealio.:thumbsup

Nordic has the 21SR on it's site, but it's a dead link:bash:

Not sure if Hallett is making their F2 anymore:grumble:

Can always look overseas too.

Some times they are just sold word of mouth. But usually they end up on the nwsra.net website. The Hallett F2 last year was on nwsra.net, skirace.net, boatrader, and even ebay for about a week. You may have seen boat 81 (yellow 20 foot Cyclone) at the US Open? My understanding is it is for sale, but haven't heard how much yet. That boat won the F2 World Championship in 2005.

You would have to find a used F-2 boat to spend ony 50k and it may not be as competitive as you need to be...right now there is a Bernico F-2 boat for sale for 68k. A new F2 will be in the 80k range.

The boat hot boat tested was 6 or 7 years years ago if i remember right, maybe longer. It only has a 200 on it, I remember because my family looked into the boat they tested as a play boat for the ocean. (We were still racing our 210 on occasion). I could only image what it would cost now. Plus factor in the cost of a new 300.

The 300XS alone is in the mid 20's and a bare hull from hallet or nordic will run at least 35k (Fiber Glass Not Carbon). That's 55k deep with out even rigging, trailer, all the goodies... Racing ain't cheap.

Your almost better off buying used over seas and paying the transport fees.

Ahh... no need then. Ive already replaced my head gaskets twice and they were 200 head gaskets. Fit perfectly too. Now, whats the difference between the 175 and 200 I wonder..... lol!

(and Barry, if you really do know these answers, I dont know the year of my motor but I do know its a carbed 2.4L and has 1 piece heads right now [not sure if they were changed or not before I bought the boat] with no oil injection )

 

[RiverDave]

I gotta be missing some of the logic here.. With a 150 on the back of it, why in the world would you want a boat like that? A real deep v style ski race boat like that, I think would have trouble getting out of it's own way with a 150 pullin a skier.. Even the plane times would take forever.

I'm not the sharpest marble in the book, but I think you would almost want something exactly like this?

And you can pick up something similar on the ridiculously cheap side? I'm not talking 50,000... I'm thinking 5K, strip all the weight out of it, and I'd bet it'd hand that Bernico it's ass on a platter with that little motor.

[gar163y]

Formula 3 originally came from Belgium's (perhaps that should be Nico's) X Class. They were all 19' Bernicos with 'out of the box' 150 Merc Optis. All stripped out hulls, no kevlar/carbon build and engines bolted directly to the transom. The rest of Europe then adopted it but opened up the rules to include any 18' to 21' boat and any 150 as long as it was a standard (not race) motor. All European boats will include at least a bow ballast tank because of the offshore conditions we generally race in. The current favorite is the Etec 150 HO and boats speed ranges from the low to high 60's. We have no specific 60mph class in the UK and F3 initially attracted a lot of interest and entries.

Lots of older hulls (Phantoms, Rings, Marshans etc) were re-engined with new 150's and the class became the single largest. 19' Bernicos and Cyclones are most common. The class has always been dogged by rumours of 'bent' engines and engines are only really checked at major events such as the European Championships. Very important in Europe is the fact that 150's sip fuel (currently £1.13/litre for Shell 98) and the boats can be towed behind a economical family saloon. The boats are so close in performance the new novice drivers had to be watched and guided very carefully in their first seasons. The class has somewhat suprisingly declined recently as people have moved up to F2 in the hope of getting selected for the Worlds Team and with no new blood snapping up cheap used F3 boats. I have not heard any rumours about F3 being included in the Worlds since Hunstanton 2005 and with the next one being in Australia, where they don't have this class, I wonder if the Aussies could provide enough boats.

Your logic is correct. The Bernico pic/ad was just showing the only F2 boat for sale right now, not a potential F3 boat.

I do have a factory Mercury manual here, and did rebuild my own personal 200 Merc when I bought the boat. If you knew it was a 2.4L,, then you already had the facts that it was larger than a 150. 175 and 200 are both the same basic 2.4 liter engine, from what I understand. Someone told me induction is the difference in horsepower, but I have not followed up on research yet.

Not sure why Merc puts the number on the tower,, I do recall not being able to pin down what year my engine was when searching for parts.

There comes a balance point though, it's not an outright boat race, you need to be able to ski behind it in slop. A tunnel is going to be a combination kite and beach ball in rough water:bash:

Ok,, now we are back to getting you on a ski to see what it's like to ski behind various boats.

We haven't hooked up a long line behind Jason's Stoker,, but if you look at any of the photos, you will never see me skiing inside the wake behind his boat. In ski racing, the skier must remain inside the boat's wake. I don't think a tunnel type boat is going to do the skier any favors at all?

My comment about the 150 and ballast tank was just a little sarcasim, since a true 150 in a V bottom boat was going to be a slow ride anyway.

Even the F2 boats with good skiers get to be more of a boat race in good water conditions, in my opinion, so the F3 class would be even more so?

My buddy Shannon had a Lab (Alibi) with a 150 on it...it would pull two skiers right at 70mph. Granted it was waaaaaaayy light and was a modified tunnel and would run basically on the prop.

Sure it can be done, but then doesn't it shoot holes in the whole idea of a "budget" class?

Now what if they made F3 skiers go on wakeboards with a single handle???

HARLAN ORRIN

Whats with all the questions about hands out front? your welcome to ski any class you want hands out front, wapped, or with a harness. We still have a hands out front class. And it can be fun. But the reality is there is a reason we wrap up. It would be impossible to ski the distances or the speeds people hit now hands out front. The guys who did it in the old days are legends but there's no way it could compare to the level guys like Todd have taken it.

Not trying to be rude, but it seems as though this topic continuously is brought up and answered
