Does someone know if it is possible to chiptune a optimax 225?
(changing the software etc. to get more hp)
They do it with cars so why not with outboards?

It has been discussed here with the before with the 150 Optimax (2.5l V6)

Can a 150 Optimax be upgraded to 200?

I would imagine for it to be possible to upgrade the 225 you would have to get the ECU from another similarly built engine ie: (3.0l V6)

Maybe an ECU from a Mercury Promax or a 250XS. You will also have to change the exhaust as well as these engines have racing exhausts, not to mind a host of other racing parts to produce the extra power.

Overall it is a very costly procedure and will void your warranty. A new more powerful engine would work out cheaper.
