Well guys, I'm loaded up and headed to the river. The boat fired up and ran flawlessly on the hose yesterday. I verified timing and set the idle to ~1000RPM.

I've still got a problem with shutting the boat off. While putting the new power pack on I had to disconnect and reconnect the black/yellow wire and ever since then it will not shut down with the key.

When I turn the key off and go to the engine and unplug the black/yellow wire it goes dead. If I leave that wire unplugged, crank the engine, then plug the wire back up it will go dead. This does not seem to be a connection issue, yet any change in the connection shuts the boat down.
