[Public-List] Andrew's message

[Hugh McCormack]

Good day Andrew,
 
Thank you for this.  I had cranked the engine over without starting it to make sure the pump was empty (I will be replacing the impeller in the spring any way) after removing the drain plug on the pump.  A fair bit of water drained out of the manifold and pump but I wasn't sure how much came out of the base of the engine.  The raw water intake drained as the boat was lifted.  From what you describe I had the same experience with the timeframe for noticeable drainage flow.
 
Cheers,
 
Hugh
