GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
You did not mention model. Year is irrelevant. If it's an old 2-stroke, such as an M25C3, just remove the intake gasket restrictor and reset timing. If it's a 4-stroke, you need a different ECU. Luis has a complete procedure elswhere on this board.

To start with must swap the M25 carb/intake gasket for the M30 gasket which has a larger internal dimeter to allow more air intake and advance the timing from 20 deg to 25 deg. This mod should have its own stickie as it's asked a lot here. Check Tohatsu 25 to 30 HP conversion under Find Threads or Search Forums....
