I bought the boat as a parts boat. I removed the plugs and put in marvel mystery oil, cranked the engine, then put the plugs back in and put the fuel hose into a can of fresh gas. The rear cap is missing off the heat exchange so the cooling water was flowing out there versus out the exhaust and cooling the exhaust.
This is a complete Mercruiser 470 from a 1984 tinker. No leaks from weep hole on the water pump for antifreeze I have a short video of it running. They put out as much horse power as an v 6 or straight 6 engine but use less gas. Some blow back out of the PVC.
Good throttle response, good oil pressure and good volts off the magneto.
It fired up and ran. These engines are getting harder to find intact. Lots of smoke.
