I talked to Mercury tech support and they said it was odd that sea ray rigged the smartcraft can bus this way on the 05’ 320. I guess sea ray rigged the smartcraft integrating it to the boat harness as there are many ways to skin the cat…My engine serials 0M39…show as an 2004 mercruiser engines which is common to have a year behind the boat hull. These are earlier engines with the 10 pin engine harness. They switched to a 14 pin in 2006. They asked to me check if both can line power on engine side are both capped off and to confirm terminator resistors at each engine…… I am digging in to all of this due to at high speeds 3800 rpm the sc5000 drops engine com for a split second and the analog sc100 tachs drop and bounce back with a lost stbd engine comm. med speed data loss error.
