You nailed it! Bypassed the oil pressure switch and the boat runs perfectly! Thanks for the help.

Good call! I'll give this a try once the boat is back together.

Oil is out. Re-gasketing and new flappers as soon as I can get them. Hopefully back on the water by the weekend to figure out the ignition issue.
