Hello to everyone at offshoreonly.com
I recently purchase a 1994 2.5 offshore engine for my water ski racing boat all was great until it developed a miss above 4000rpm. Had a look under the cover nothing I could see. Next day tried again wouldn't idle properly or even get the boat off the plane, engine running super rich. Took it to a merc dealer ,mechanical electrical all ok, plugged the DDT into it ,motor running an s3000 ecu (A61) Said I would need a new computer.
Can I rechip the motor?
Does anyone have a copy of the 2.5 offshore chip on their computer I could download? I would be more than happy to send you a copy of my S3000 chip ,Mechanic said the rev limiter had been removed.
Boat has been out of action for 4weeks, Help!

Hey Ski Racer ,
I have two 1994 - 2.5 offshore , But they are carb motors not EFI. If you go online and check out Mercury parts Express they might have what your looking for. Hope this helps you. Good luck!

Gassticks,
thanks for your reply. I tried merc express as you suggested but it looks like they could only supply a whole new ecu ,scary price once you double it to get to New Zealand dollars

Cheers

Ski Racer.... might try the" Scream and Fly " message board alot of those guys are running the merc 2.5s good luck

no problem getting your ecu re programmed but your going to have to send it to the states , its around 50 to 75.00 u.s. dollars. caontact me if you want more info. [email protected]
