Tohatsu 50 efi tuning and mods????
Hi - I've got a little development project / design underway and going to be powered by a Tohatsu MFS 50 (4 stroke). (15" shaft)
Will run this as stock to start with but them looking to get any more power / torque possible from the engine.
I had heard someone in the States (I'm in the UK) is doing a re-map for these. Wondered if anyone had details - or other mods that can be done.

the 40 50 60 all look the same to me! meaning compare parts. i bet making it into a 60 is simply a matter of an ecu swap. not cheap! id also pay attention to the throttle body/intake. might be larger? dunno.
