Well I fired up the F100 today. Even with the new oil, I got that ticking in the top end once it warmed up. It ran fine on some CAM2 I had lying around (no ethanol).
Oil pressure is fine, as far as I can tell. Not sure what I can do. I think the motor has 800 hours on it. But it came off a rental boat, so it could have 2800 hours. No ECU, so I can't tell.
The outboard cost me about $1000, so I am not sure I want to tear into it unless it sounds worse. It *IS* a solid lifter motor.
