What's with the Front cover from an Inline 6?
That V6 has been apart, the bolts holding the Crankcase together look like an Impact was used on them

You said it ran before you bought it. What else changed? You had to have unhooked the Wiring Harness, when removing the Motor from where it was to transfer it to your Boat. All wires hooked up correctly?
