Similar problem - no Water at all - is there really a way to prime?

Hi all,

I just got my boat back in the water after a broken prop and bent shaft (long story but it has to do with a submerged deadhead and on the way OUT on a 4 day weekend. grrr...)

When I started the motor up I had no water move through the system at all. Last year I replaced my mixing elbow which was the culprit but I can't imagine it built up soot and blocked again so quickly.

The boat has been in the yard for work (and waiting for parts) for about 45 days and I could not find any blockage when I checked the sea ****, strainer and impeller this afternoon and all seemed to have water. Any ideas what may be the problem? When the yard replaced the prop shaft, does that have any effect on the cooling system? Is there an easy way to check the heat exchanger? Could it be something simple I just didn't see? Yes, I opened the throughull

I noticed a couple posts about the pump "priming" how would I bleed air out of the system to prime it?

thanks in advance!
Matt

I found the problem, On a strong starboard tack (my thru hull is on the starboard side) the thru hull comes out of the water allowing the hole system to drain and loose prime. I am going to install a check valve between the thru hull seacock and my raw water strainer. I've had the boat since 2001 and never had the problem until now. I just replaced my sails, and therefore heel more. Thanks for all the input.
