computer reprogram
 

anyone know a reliable place to send a merc 555 to go from a stock 5.0 to a 5.7. on east coast preferably Thanks.

Don't know of anyone who can reprogram a 555, wish I did, it comes up often

Thanks have used whipple in past. on west coast. Got good results but took 3 weeks. and lots of phone calls. anyone used Hardin Marine in Fla.
