Default 2100 Br New setup

HELP! I need advise. Last season, sadly after running a heavily modded 2000 Mercury 225 EFI on a 2100 BR FOR 9 years I melted a couple of pistons and badly ate my Block. My marine Mechanic is saying go for a used stock 2015 250hp Optimax pro XS with less than 200 hours that he knows. I will ask for a leak down and hour log if I drop the cash on that gamble. My question to everyone is what is the better setup? Results wise I was consistently getting 82 Mph Turning a turbo TXP OT 4 29 p with 15Ē of setback and my Titus coned fleetmaster with fat shaft mod (that was modded a couple of years ago for 2000$ after the shaft let go at 75 mph!). My motor has a 300 X ECU,Billet Simon heads (not sure how many ccís) ,Poppet diverter, Simon lightened and balanced flywheel, and cut down exhaust can. So maybe 260 -270 hp?
When I bought the boat the guy was claiming 89mph on GPS Running a Labbed trophy plus 27p ..... only thing was it was on a river downstream .... still pretty good numbers with a Labbed Trophy plus 27p. Sadly I lost that prop when I sheared my shaft. More realistically on a lake it would run around 85 maybe 86 mph with that prop before I lost it. The current setup is running premix premium gas which Iím finding a bit of a nuisance and the wife and I are getting pretty tired of the noise from the cut can when just cruising. Donít get me wrong I love to go fast but my mechanic is saying to expect 82 mph with the stock engine with better fuel economy and rock solid reliability. I do like that and am not prepared nor do I have the technical expertise to tinker with this. It is good to know your limits. However if Iím not happy I am open to having it professionally tweaked.


I donít like to go backwards as far as performance (who does?) is concerned and LOVE how much this motor accelerates with that lightened flywheel from 30 to say 60 mph it REALLY puts you back in the seat and is a lot of fun hopping out of waves.
Any hands on advise with the 2100 BR or closed bow would be GREATLY appreciated. I want to make the right choice here. If WILDMAN is out there I would love to hear his comments as I know heís the best when it comes to setting these boats up. I AM PARTICULARILY INTERESTED IN WHICH LU everyone feels will be better for my app. I feel that Fleetmaster is a pretty special unit and wonder which is better for bow lift for my bow rider which I feel lacks that as all bow riders do. Also blowout tolerance? I have no experience with the TorqueMaster re top speeds and blowout tolerance but know I have no issues with my 3 hole Titus fleetmaster (1.75) I currently have. One thing my mechanic is saying is this will not have much in the way of resale value if I decide to sell it after rebuilding as is and I agree. Other thing that is hard to argue is the tested reliability of a stock motor. Although 9 years of running is pretty good. Thoughts people? Your help/hands on expertise is ALWAYS appreciated. Also what is a realistic expectation speed wise for the 250 Pro XS and what can I do in the future if I want to tweak it? HELP!

Well, I'm not an expert but I do have a 250xs 2100 br. I would try and find one with a Sportmaster leg but they are rare. 300xs are easier to find with a sporty. Mine has the TorqueMaster, they do have low water pick ups in the nose of the bullet but they also have the 6 per side lower leg water pick up openings and most recommend plugging the top three on each side if you want to run the motor raised so the prop centerline is at or above the pad on the hull. Likely you were there with your set up to hit those speeds, so you will want to duplicate that.

Sounds like you already have the basic speed formula for a 250 or 300xs on a 2100 with 14-16" of set back, running the prop shaft centerline even with or 1" above the pad and a 27-29P Trophy plus.

Everyone likes the fuel economy of the xs motors and they are pretty reliable but do have some known issues. Compressors seem to be a bit of a weak point and coil packs can be an issue too. Like you did with your old motor, I find my 250xs a bit too loud anytime I'm going medium speeds cruising or pulling tubes and skiers, but I think it may be a little quieter then what you had.

Over all I don't think you will give up much or any performance with a 250xs as they make 270 - 285 hp as well. You will certainly gain some if you find a 300xs.

250xs are set up to run 87 octane, but to get ethanol free fuel I have to buy premium anyway, so no savings there for me. But maybe your location is different?

Good luck

With your current setup and a 250XS you will definitely see speeds in the low 80's all day long. Step up to a 300XS with more setback and you will climb into the 90's with the right prop. Just for comparison, my old Pulsare 2100 long deck with 13.5" of setback ran 77+ with a bone stock 225Xri and a Trophy Plus 26. My yellow Starflite ran 81 with a Pro XB 250 and a Trophy Plus 27..

We have a 1995 2100BR with an 07 250 ProXs, and it is a great combo, 80 MPH and unbelievable fuel economy. My motor is completely stock, and run a worked 27 pitch Tempest plus.

Thanks for your detailed reply. I appreciate it. I will probably keep my Titus conned fleetmaster and put it on the 250 Pro XS as it has the LWP IF it fits. He did mention what you said that some of the holes need to be plugged. The speed range Merc recommends for the TorqueMaster of UP TO 85 mph concerns me as I have had the boat up to that speed and donít want the blowout.

I did have a Labbed 27p Trophy Plus and it was the best prop for speed but that let go at 75 mph and took out my prop shaft so will be looking for another when I get set up! The other prop is a Turbo TXP OT4 29 p and that pushed me to 81 on a regular basis.

My motor was pretty loud primarily because the can had been cut so it is nice to hear that it will be quieter. I am SO looking forward to a more stock motor but the specs for a 250 XS show 91 DB at 6000 RPM so not sure how much quieter it will be. Weíll see.

I am looking forward to ditching the premix and getting the better fuel economy and reliability of that proven motor and saving on the oil with the oil injection, running premix is smelly and expensive.

I do and will run shell premium so as not to worry about ethanol it would be nice to save the 15 or 20 cents per litre running regular but I am not up for all of the issues of ethanol in my gas .... there are a few more BTUís in straight gas as opposed to gasohol not a lot (maybe 1%) but it is peace of mind and no headaches especially when you are talking a lean burn down. Believe me you donít want that! My motor melted two pistons and trashed a couple of reed cages and ate the bottom end so my block is kaput. OH WELL IF YOU WANNA PLAY YOU GOTTA PAY!

What is your setup and what kinds of speeds are you running with your BR KAZARUS?

The Tepest is one of the props Iíd like to try ..... how is it to handle and what is your setup (setback and LU) A lot of people comment that it can be a handful but is good for speed. If you have the TORQUEMASTER any issues with water pressure and what pad height are you running? Thanks for the info BTW I appreciate it.

Pulsare 2400 Bowrider with a Verado 300 Pro running a Bravo One 24 at a measley 71mph on GPS..It's not as fast as the 2100 but handles much bigger water.

The other "stepped into" boat is my 1984 2800SX Outboard that now wears a pair of 2002 Mercury 250 efi's...speed remains to be seen once I mount some Bravo One FS 28's on her!

Hey FlyBoy, I had a 2011 pulsare 2100 closed deck with a 2010 250 ProXS. 12 inch set back bracket and 5 inch setback with jackplate. total 17 inches. Ran the prop at 1.5 inches below the bottom. The torque master lower handled the height just fine. It has water pick ups on side and in the front of the bullet that always gave me plenty of water pressure. I ran a 27 inch Fury stock which very few people do but I got 82mph any day of the week and saw a best of 84mph twice. All GPS recorded of course. The Pro XS is an awesome motor runs on 87 octane I believe but I always used 91 or greater. The closed deck I liked cause of the look and it will run a bit faster than the open bow for the most part, but for conveniences the open bow is great when you have more people and you are all laying out anchored somewhere. You can always snap a cover on the open bow that may help a bit with top speed. Good luck Steve.

Thanks for the scoop.I decided to ditch the torquemaster and go with my Titus coned fleetmaster with LWP Just coz I DONT WANT A BLOWOUT. My motor is going to be the bastard child when I'm done but I won't have any issues with water pressure or blowout.
Soon after I get the unit back and I get used to this new motor I going spend the day at my prop shop for a day of testing (tempest,Fury, Trophy and scorpian and my hydromotive 28 txp ot4)at the end of the day he'll get my best prop for labbing and thinning). Hopefully I still see 82 with this 250 otherwise I have been wondering about some form of aftermarket chip my mechanic
Mentioned. I hope my motor can turn my turbo 28 otherwise it might be up for sale.

Thanks for your help you have confirmed 27 pitch is a good starting point especially for my open bow. They tipically need more bow lift so it might be the trophy. I lost a blade on my labbed trophy 28, it was my best prop but that motor I suspect was doing 280hp so no problem Turning it. Re the bow rider well this is our family boat so we have room which is nice but I am a go fast guy but made the sacrifice for the family.
