I've been known to take a mouthful of water and blow it back though the hole and that usually does the trick. Otherwise, a can of air like is used for cleaning keyboards should do it. Or I have heard of using a piece of line from a weed whacker to clean out the hole, as well.

More then likely you need a new water pump installed. There should be some intakes on the lower unit that have screens on them. Make sure they are not covered up and if they aren't then I would take it in ASAP to get the pump replaced.

      Strange indeed... Try looking for much more slack water compared to the beech you were yesterday and today. The West side of the dam was on fire this afternoon; a friend and I were in the double digits within an hour.

      fished a different spot today and it was strange, I was using crawlers and a lot of eyes bit and only 1 sucker.  guy next to me was using earthworms and he caught a lot of suckers and 1 eye.  twilight zone ! !  LOL  I just use a slpit shot most of the time.

      All we ever use is a few bigger spilt shots and float/bobber with crawlers.
