Hunted on a large river with lots of “surprise” sand bars. At O’dark thirty it is very difficult to see them and I had to trim up and motor across a couple of them this week. Yesterday my motor was acting up and had to basically idle back to the ramp to keep from over heating. I took the lower unit off and checked the impeller, housing and such (new kit on the way) There was a bunch of fine sand in the housing and the outlet tube was basically plugged. Any tips to avoid this happening, aside from the obvious of avoiding the sand, is there a way to clear the outlet short of tearing the lower apart?
