Really easy Mark. You see the motor housing in the back? Its really easy for water to get in it where the motor housing meets the main bandsaw unit. Just silicone around that area so that water can't get in and leak into the motor housing. I'm not sure how necessary this is however when I took off the motor housing it did not look like the motor would like any kind of salt water near it. I did it more as a precaution than anything else.
