If it is getting all messed up, and has a lot of scratches, just use a little steel wool, polish it up and then use touch-up paint, metallic, Evinrude Johnson, they also have it in white. And if the burr is not that big, then you can use some steel wool. If it's pretty good size burr, I'll just use a file and file them away - just smooth it down. So what we're trying to do is get rid of those bubbles. When that motor's going through the water at 70 plus mile an hour, if there's any catch on the edge of those props or on the fins, that's going to cause - create turbulence, it's going to cause air bubbles. The two things wrong with that is one is you can cut your fingers on it just by holding on to it, and the other thing is that it creates air bubbles. I got a couple of pretty good size burrs on there right now from where I took off in some extra shallow water. So it's going to get banged up from time to time. It's down two-feet below the boat so anything that's down there, the lower unit's going to hit it. But the lower unit is as deep as it goes. So you've got to pay attention and try not to get into too shallow water, get around those rocks, and do some damage to the propeller. Like if you come into shallow places which where I like to fish a lot, lower unit's the first thing to hit the ground so it's easy for it to get damaged. And the problem with the lower unit is being down so low is it wants to hit the bottom. That's what turns the prop, it's where the exhaust comes up, some of the motor picks up the water. ![]()
