Merc Racing Opti 200 XS?

**hsbob** · 06-12-2006, 08:43 AM

bass and walleye quoted 245, but that just dreaming.

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.

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

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

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.

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

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

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 ?

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** · 06-21-2006, 05:45 PM

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** · 06-21-2006, 05:46 PM

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

**debortolic** · 06-21-2006, 05:47 PM

from (LOL)

**1BadAction** · 06-21-2006, 06:30 PM

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

**espen** · 06-21-2006, 07:26 PM

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.

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.
