I'm hoping someone here can help me figure out how much damage I did today.<br /><br />I was running my boat today through a channel at high tide when I hit something below the surface. It must have been hard as hell, because about 1/2 inch of one of the prop blades is bent over, and the bottom 1 inch of the lower unit is sheared off. The engine vibrates a little, but I was able to get back to dock at 1500 RPM without incident.<br /><br />I can replace the propeller, but I'm wondering if there is anything else I should check on. What will be the effect of missing the bottom of the lower unit? Any advice will be greatly appreciated.<br /><br />FYI, the engine is a 1994 OMC 150 HP.
