Fly by wire

Is it possible to convert my 1999 mpi mercruiser 5.7 to fly by wire?

Short answer is no, not realistic. You would need an intake with the DBW throttle body that fit that gen Merc. Throttle assembly with the TPS, a DBW generation ECM. Thats all the easy stuff. Next, you would need the wire harness to match all of that. 

Curious as to why you want DBW?

Thank you, sounds like a no then..

I just thought it would be easier to hold a speed for other drivers...

Your throttle should have enough tension to hold.

It does for me, but when others are towing me they cant idk why. Might just get perfect pass  , it's just I am going to get a different boat after this summer and wasn't trying to throw more into this one.

PP would a fraction of a DBW conversion and a tenth of the time involved. It will help with resale as well.
