Any help would be greatly appreciated with the following mystery:
My boat partner and I own a 2003 2858. Just after he left the Whittier harbor last weekend the alarm sounded, the engine started to sputter and he shut it down. The engine was overheating and we figured it was a bad impeller. We replaced the raw water impeller (half the splines missing), back flushed the heat exchanger and the oil cooler to get all the impeller parts out, and put it all back together.
When we tried to start it up to check our work, the engine turned over strong but would not fire. This is very puzzling to me, as we only fooled with the cooling system, not the fuel or electrical systems.
Thanks in advance for any hints!
