Hi folks, I've been trying, unsuccessfully so far, to try and determine if the engines in my 2005 Regal 3560 will support a J1939 connection. My ultimate goal is to convert the J1939 to NMEA 2000 and feed the info to a new plotter. However, I can't seem to find out if the engines will even "talk" J1939. Best I can tell is that Volvo started supporting J1939 around 2005 and then supporting NMEA 2k with the EVC engines about 2008. I would appreciate any help in answering or pointing me in the right direction. FYI, I've already sent a note to Volvo Penta with no response and checked with the local dealer (he had no idea what J1939 was). Engines are Volvo-Penta, Model 8.1 GXII-D, Thanks. John
