We were out on a friends Searay 370 yesterday and noticed that the port engine was putting out a good amount of black smoke. When we stopped to check it out the motor was also putting out some blue smoke. It doesn't idle or seem to run any different than the starboard one (or at least not enough to notice it). I do understand the black smoke is probably from running rich but the blue smoke is more of a concern. Both motors are 1996 EFI MPI hooked up to what seems to be a v drive system. I am more familiar with outboards than these big boat motors and all the complicated systems that are inherent with these powerplants. Any help or opinions with this will be greatly appreciated! My idea on the blue smoke is it could be valve guides or rings, other than that i am at a loss. With them being injected my thinking is they could be scanned to see if there are any codes. Thanks in advance!!!!
