Honda outboard 115-130hp upgrade??

 Hi All,

I currently have a 2006 honda 115hp on the back of my 5.8 chivers meridian. I have been doing a bit of research and have come across that the 115 & 130 is exactly the same motor and that the 115hp is just a detuned version..

Does anyone know what is involved to have the motor tuned to the 130hp? Would you need to replace the ECM or do you think it could be unlocked and mapped to the 130 and info would be appreciated and if anyone has done it give me a shout as to who and where did the work and is it worth it?

 

Cheers!!!
