200 mariner modifactions...

[Contractor]

i have 2.5 200 mariner super mag efi..other than head's.. how can it be modified & live..????

Get an ACU from Brucato. The 200's are very strong motors with a good ecu

 

[Contractor]

anything else..??

 

[patches]

Maybe an SVS. I personally would be hesitant to do any block mods cause I know how strong these motors can be if you get the fuel right and 145 lbs of compression. The Prostock class in DSRA runs stock 200's with a good fuel curve, 16 amp electrics, and 150 lbs of comp and they are very impressive. 100 mph in the 1/4 on 1400 lb boats

 

[Contractor]

getting the fuel right..i think is the KEY.. you are so right.. this motor is very strong...

 

[Contractor]

if i mod in side of this 2.5 200 super mag.. how do you set the fuel curve.????

Send the ECU to sean a Rapair and tell him you want the ProMax Recurve :twisted evil

I know a recurve is cheaper, is the promax curve that much better, or does it just give you more RPMS, I am looking at that as being my next mod.
Either a recurve or ACU from Bructato.

Where is better to get it done, RAPAIR recurve havent' checked, Simon Recurve $350, or Brucato ACU $900?

BTW, not sure if mine is possible it is a 1995XRI which is most likely analog, need to check.

A unit that can be configured by you is by far cheeper in the long run.

I have the same motor. Shaved the heads, put on a front half from a 225 Pro Max, and re-programmed the ECU.

Hmmmmmm pm Jeff Calbaugh (Hotprop here on the board, he's Glenn Reynolds' lead wrench and engine builder). He can wake that lil 200 up and have you showing your transom too ANY 225PM you come upon!! :twisted evil

thanks 4 all the info... with 150 lbs of compression will the stock fuel curve in this 2.5 200 mariner super mag, send the engine enough FUEL 93 oct..or better..with timming on 25..???

 

[xb03fs]

Just noticed you say super mag, that is the same as the promax, so you already have the raised limiter. I want a raised limiter like yesterday

 

[Contractor]

yea...200 SUPER MAG..!!! raised limiter meaning FUEL..????

Do NOT use a Rapair unit. They are nothing but trouble and very slooow customer service just to get it back and still not work. Took 4 years of getting jerked around to finally get smart and make the change!
I switched to a Brucatto PCU and everything is rosey now.
