- MerCruiser 8.2 Mag V8 Big Block w/ Bravo 3
Have a MerCruiser 8.2L V8 Big Block engine with a Bravo III outdrive. We removed the blue plugs (3) to drain the water from the block, after the water drained out I put the plugs back in and put the muffs on the outdrive to run antifreeze through it.
Dumping antifreeze into the bucket we noticed the engine will not suck any of it up into the engine. I checked to make sure that the air was released from the valve and all plugs were reinstalled.
Then I tried to hook a hose up to the muffs to provide pressure to induce suction from the motor and nothing. The motor will not suck up water or antifreeze. We just took the boat out and had no issues during the season… very confused at to why it won’t create suction. Any input would be greatly appreciated.
