Mercury Optimax Ecu

Hi There,

I'm owning a 200bhp optimax 3.0L from 2000 .... ( 300 hours on it)

I would like to get some more power ...
I can buy a 250 racing ECU ...
link from ebay:
http://www.ebay.com/itm/300815249579...WAX:IT&vxp=mtr

My question is does it fit ? Do I have to change something in my engine loom ?
Is it just PLUG & PLAY ?

Thanks
Ben

Probably not, here's why....

200 3.0L Opti Throttle body 83949T03
250 3.0L Opti Throttle body 841194T04 (£348.13+VAT)

200 3.0L Opti Air compressor 8M0048555
250 3.0L Opti Air compressor 8M0048556 (£912.23+VAT)

200 3.0L Opti Crankshaft 482-9784A11
250 3.0L Opti Crankshaft 482-842753A02 (£919.03+VAT)

200 3.0L Opti Reed block assembly 828623T6
250 3.0L Opti reed block assembly 840418T04 (£232.11+VAT)

That's only the start, many more £1000's required.

My advice, sell the 200 then buy a 250

thanks for your comments...
I'll try to buy a 300Xs ... Nico Bertels ( Bernico ) had one at 10.000€
The 200 bhp is like new 300 hours on it ... run like a beast but I'm building a 6,95 rib ... need extra power
