A couple weeks ago, I bottomed out on some river rock for about 20 yards and I noticed my pump took a bit of a beating. The intake grates were all mangled and pretty certain I have to get an impeller job done here before I take her back out. Just thinking about it makes me cringe for my transom as well. I looked all around the outside for any cracks and I couldn't find any Still looked pretty solid and intact. Just watching it bounce back there while we were skipping across the rocks didnt look to good. My boat is an 2001 1866 smoker with a 100 Yamaha pump. Which is a lot of weight. Actually thinking about a newer 80 pump. Anybody ever rip a motor of while river running?
