I have an 05 Sanger dlx with the 8.1 mercruiser. Rod bearing went out in it so I pull the engine and rebuilt the bottom end. Went to start the boat back up and would not start, just turned over. Took it to the mechanic And found that the computer had been burnt up. Sent it to whipple to have it rebuilt and found that it burnt the sensor grounds inside the computer. Was told to put it back in and try to start it again when I got it back. Burnt it up again so I sent it back to get rebuilt. Boats back at the mechanic now but we are afraid to put the computer back in it. He did some checks and found it's getting 12v to the sensors when he plugs in only the big plug to the computer, the sensors I assume. Then if he wiggles the wiring harness where it attaches to the computer it will drop to 8v, then back to 12v. So we are thinking the wiring harness is bad and causing a voltage spike, and burning up the computer. Anyone felt with this before? Sound like a reasonable assumption? When I pulled the engine I left the wiring harness on it and never took off anything from the top end. Only took off or disconnected what I had to.
