Sucking up sand
What's the worst that can happen from sucking up enough sand to plug the sea strainer to the top?
that's the last time i head to the sand bar.

If sea strainer is full of sand then so is motor. I would clean out strainer. Put Motor on hose & run for little bit until water comes out exhaust. Open water drains in side of block for a little bit then close. Do this until you have no sand coming out of block. You may have done some damage to the impellor in the water pump. I would replace it now. Easier to do now then wait for it to fail when you are planing on a day on the water.

i was definitely the dredgeking this weekend. mercruiser makes a hell of a dredge pump. a lot cheaper than the custom pumps we build. i wonder if merc makes pumps 20" and larger.

the worst part is i had my surveyor with me to keep me out of the shallow spots. hmmmmm. may have to re-evaluate his pay this week 
the fresh water flush helped back flush the outdrive. took apart the hoses going into and out of the pump and flushed those. had it running and flowing water last night. need to check/ replace impeller and maybe check a few more hoses to back flush.
