Merc Racing Opti 200 XS?

[feelgood]

Is it the old 2.5 block? Does it have the heavy duty swivel and trim? How much does it weigh? How does it run - like a 225? I can't find any specs on the Merc web page. I need it to replace a 260 EFI on Allison XB2002.

[Bullet250XB]

Set one up on a 20Xd Bullet,it was A suprize to say the least, Got 78.9 Gps loaded to fish.Thats with two guy's over 200,Tanks gas. They are strong, and get ex fuel mileage.Don't think you'll be sorry.

I have one on a 2003 Allison. You will be suprised!! I can run 83 to 84 With two people and a tank of gas. I have ran 86 to 87 with just me.
Some have broken the 90's on a 2003. You should be able to get to the 90's pretty easy on a 2002.

I used to have a 15" 200xs on a LIGHTNING Mirage copy and it ran awesome to be a 200 top was 91mph gps with a 29srx running on the limiter.

[hsbob]

allong with the above you'll find several test reports at bass n walleye mag on allison boats. i have found it to be the healthest 200 i've had [all on the same HS voyager]. the best benifit is the fuel economy. i have the full smartcraft guage set with a gps and have gotten 7.4+ mpg at over 50mph. my top speed is currently 74 but that against the limiter. im sure it got 80 in the boat[ with the SM LU}. so far it the best 200 i had

[pengilly]

How much do those 200xs go for?

[hsbob]

my 2004 was 14500, saw a 2.5 xs at jasco 11500. ggo dluck.

[pengilly]

thanks hsbob,
I have a 18' Rapidcraft Hurricane with a 88 175 merc. I wonder how much of a performance gain I would realize going to a 200 xs? The sportmaster gear case and better fuel useage would be welcome improvements. The hurricane has a v-bottom without a pad and while its a great all around boat I think that fact is what keeps it from being a stellar top end performer. Im going to radar it this weekend and see where its at now with LW, jackplate, and 25 Spinelli chopper

[hsbob]

you'll be adding 30-40 more hp. dont really know what the 200xs really is. its has more torque than a efi 200 and definetly more top speed. my son and i have identical boat with different motros [200efi and 200xs] so the comparision can be really seen. i do know he used twice the fuel than i do.

[1BadAction]

awesome motors... if I didnt find what I have new, I would be rockin one. sure would have been better on gas :o

[espen]

Hi ! I read here on s@f that 200xs did perform as or better than a 225 promax. If it did sound like a 260 I would buy one ;-)

[WATERWINGS]

Whats the diff. between the 200 and the 250, weight? max RPM's?

.....also, whats the diff. between a bass boat, and a walleye boat?

The look the same to me??

[hsbob]

bass boat are close to what most of us use at S&F rigged for fishing.

walleye boat are closer to normal runabouts but rigged for fishing, front seat, trolling motor....

[pengilly]

i wonder what hp these are putting out at the prop? anybody heard or dyno one?
jeff

[hsbob]

bass and walleye quoted 245, but that just dreaming.

[rock]

I have heard 240 from several different sources. I have one for my XB2002 but have not hung it yet since I need a cowl. Currently running high 80's with a fairly stock 200 on a 15" offshore with a CLE. I'll post the difference if I ever find a cowling to fit. Buddy has XB2003 with a 15" XS and is consistently low 90's. I can't wait for the fuel mileage.
Rock

[hsbob]

dont worry rock the economy is there. got 7.5 with gps and smartcraft guages on a voyager. you could get better.

[David]

I'm not buying more than 220 HP from the 200XS. BIA is +/-10%, not that they mention BIA on their website...

200XS is 2.5L, claimed 434 lb
225XS and 250XS are 3L, claimed 505 lb

[pengilly]

I ran the 18' Rapid craft with 88 175 this weekend and with a 25 spinelli chopper, 5.5" CMC powerlift, LW and no testing, my first pass was 70 mph. Right now all I have is the hand trim and throttle, which make driving "challenging" to say the least. My foot throttle and trim should be here this week and we will go back and test again. Im thinking low to mid 70 should be easy enough. This speed was with a stalker stat and the rpms were at about 6400-6500. I can get another 5.5" of manual setback for $135 , but I want to test this setup more before trying more setback. When I get it optimized, id like to get some feedback on what a 200xs would do for this boat, any guesses? The Rapidcraft is a padless V bottom.

[1BadAction]

220hp and a ton more TQ than a regular 200... thats why it feels faster.

[debortolic]

we use a 200xs on our offshore, we test it and it's very close to 200hp.
It was a big difference when we came from the XR2, even if we pulled out of it 185 hp.
ciao from italy

[espen]

Hi Debortolic !
Great to see someone from Italy and Venice has to be one of my favorite places , if you love water you have to love Venice :-) I remember we told the goidolier that we where boat racers and he started passing the other gondols , fun.
Are you racing in UIM 2L? Here in Norway I think there are a weight penalty for the 200xs boats , the tuned xr2 I have heard are close to 220hp ,I think the offshore rules are a little more loose than the round circuit sst120 rules . Last race I saw xr2 still more competitive in smooth water.
Since you have the hp figures you probably did run the engines in a dyno ?

[espen]

One thing that makes my gearhead think is the possibility to convert a 135 or 150 optimax to a 200xs . I have heard the porting are different but rods ,pistons ++
all electrical /ecu /injectors are the same as I understand.

[debortolic]

as far as i heard 200xs is very close to optimax 200, but i do not remember what part changes.
Anyway, we compete in offshore class 3/2LT and all of us (and in the world Champ. UK, Finland, Sweden and Norway team too) has been using mercury 200xs since 2005.
Well from the xr2 probably i can pull out a lot af HP and RPMs, but what it is allowed in the Championship is very little.
We use to be always first since 2004 and the judges always wanted to open up our engine checking out everything (100 euro for gaskets every time!!!!)
To be precise, i knew our was about 187hp (check the pics!!!).
Now we are working on the 200xs ecu, but it is very difficult 'cause we have to tune it leaving original datas displaied on the DDT when judge checkes it after race (did i explain my self correctly??)
gotta go to get some sleep
see you
carlo

[debortolic]

ecu is definally different from 135 and 150, as i know also form 200

[debortolic]

from (LOL)

[1BadAction]

you can tune the ECU? any way of making the REV limit higher?

[espen]

What I heard is the ecu is the same on 135/150 opti but needs reprogramming for the porting difference and higher compressor pump pressure.
Last race I saw was last year , winner was xr2 on a Argo cat doing 92 knots.

[willyp]

I would be curious to know if they are any modifications that can be done to the 200XS. I mean dont get me wrong on my Allison I can run around 85 to 86 loaded. Now some have run 90ish. OK Here is the deal. Those with the 260's and 280's run mid 90's to a little over 100. Now for me to get another 5 to 10 mph I would need to get a 280 to replace this 200XS that would be 4 to 5 grand. Thats a bunch to me for a few MPH.

What exactly are you changing in the ECU calibration.???


Thanks:cool:

[debortolic]

That's what i'm working on and this is not difficult at all, mostly if you need just to fly around or go fishing (anyway we have some tricks we have to try sooner or later, send message in pv, will let you know)
the problem (our problem) is the 200xs ecu (and probably the same do the others' type) saves datas and shows it when the DDT is plugged in as following:
1st step: 0 to 1500 RPM
2nd step: 1500 to 2350 RPM
3rd step: 2350 to ...
... and so on till 6785 (limit) or something around it, and counts 1 cicle every 6 minutes you last in the step range (excuse me if my english is not so technic)
based on the torque curve and the time spent in each step the DDT tells the DDT (race judges) which engine corresponds your ECU.
Now, solution would be, when i will be able to tune it right (a guy in Milan who sells the file for 1500 euro, something like 2k $, say it add it 30hp reaching 7250 rpm) not to exceed the 6 mins of over rpms during the race, and delate datas every time just before the race
will love to see 225 xs ecu curve (you guys just might try that ecu on your 200xs).
Any of you as any mercury PC based software??? We are looking for it everywhere, if someone has it please let me know.
have a look at those (we have the old XR2 on) http://forums.screamandfly.com/Gallery/showgallery.php?cat=500&ppuser=22176
Have to go study

(1) Absolutly impossible. But I'd be interested in what he thinks he can do.

(2) Won't run good at all..

(3) You can buy a licence and software thru Mototron. If your a legitimate business.

[espen]

Only Idee I can come up with are to mount a nos system with extra fuel .
Computer controlled or not , its impossible to go around mecanical limitations and air/exhaust flow with ecu changes.

1) check out www.turmax.com NAUTICA and SEZIONE ELETTRONICA
2) was just wondering about the torque curve, do not know differences between 200xs racing and 225xs racing
3) i checked it, can't find the right one, i just find smartcraft everywhere

thanks carlo

1) what does that have to do with an Optimax

2) theres a lot more to deal with than just the torque curve

3) http://www.mototron.com/home.asp

That would be a good idea, Keep the efficency and shoot it with NOS when you want to play. What does the computer actually control. Is it just fuel and timing. If thats all Could you get a after market computer that does this and adapt it to fit to control fuel and timing. I mean the tuning would be a pain but could it be possible.

[espen]

Hi ! I think a better Motec ecu could do the job , its about controlling 12 injectors sequential, I have heard pretty special start up strategies on the optimax engines before the compressor pressure is up , fiering just 2 cyl or something like that . Maybe get a friend at Orbital engines and ask what ecus and cal they have used on their experimental engines , would not be suprised if they have used Motec , both beeing down under.
An other option would be to build a 280 with 200xs heads and optimax electronics and also keep the 280 efi system (or pcu), running 280 system at high rpms. Trow in some exhaust valves and maybe you could use the oem 200xs cal ,then out with the exhaust port restrictors and in comes the PCU..... It would cost more than 5000usd....

Best would be to log timing and milisec openingtimes on both fuel and air injectors on the oem engine vs /rpm , map pressure and then convert this to the Motec ecu as a starting point.

I think maybe its easier to fit 1 or 2 injectors in each cyl like they use on the Yamaha HPDI engine on a 280 and use a aftermarket ecu to controll them .

Wait until Mercury makes that engine : a 2,5l 290 hp with variable exhaust valves and direct injection , I dont think the Orbital system are needed at high rpm.

Hi ! Did a net translation on the www.turmax.com (http://www.turmax.com) info in Italian:

On request of some team race, we developed the file for the Mercury 200 XS with best resulted. Lifting alone the limitatore you turn, we make one's will the engine 200 XS on the bench experiences considerable engine 198CV to 6800 original turns and 179CV to 7200 turns.
Riprogrammando the original switchboard, without to intervene on the engine, we succeeded to obtain 210CV from 6700 turns until 7200 turns! The greatest summit of development (+30CV) we obtained it to 7200 turns.
The SmartCraft and the connection with the diagnosis of the tester Mercury remain unchanged and does not come signalled the outside turns (contattateci for greater information).


The cost is of 1000,00 €

[willyp]

Has anyone tried that program. Would be interesting to see if that holds true for the RPMs and I assume it does not add any horsepower.

[debortolic]

3 French teams got it to race on the 4LT, and that guy from milan said other 2 guy from Rome bought it... guess i know who they are, in the first race they were super fast... and they are both from rome...

Anyway the Frences said it works great, that's all i know
but i'm investigating to see if it true, that is mostly why i joined the forum.
I will let u know as soon as i have any news about it

[willyp]

Keep us posted for sure. I know they are doing things within a limit(rules) is there anything that can be done where no rules apply?

[pengilly]

Thank god for the Itallians:)

Go Valentino Rossi!!!

Please keep us informed and very nice boat you race. I wonder if 198 hp (200xs) is enough of a gain over my 175 to hit 80+mph when im at low 70 mph now?I also found out that i have a friend that works for Merc. I explained my situation and he is willing to make the call to find out prop shaft horsepower. If its not enough to justify the 200 xs he said hes sure he can find me a 225 promax. Im sure looking forward to hearing what merc claims, ill pass it on to you guys.
jeff

[pengilly]

210 hp is what he told me. give or take different motors.

[mercman13]

What can I do to my 200XS 2003 to get it going faster? 18 foot boat 400 pound boat???? Any ideas????
