Hello
I'm looking for any information you can provide on a Graymarine/Detroit Diesel. It is in an oldcoast guard 30 foot boat built in 1958. and now owned and run by the seascouts. It is a 6-71 with the model #671RA48A and a serial #6A34647 are stamped in the block. I'm trying to find out if the if the currentinjectors are the right ones and if the full load rpm's are set right. itcurrently has HV7 injectors and the full load rpm's are set at about 3400. Everything I know about these engine tells me the full load should be about 2300.Any help would be greatly appreciated
