Do you have your steamwheel for the PCU bolted down or velcro'ed? I was going to bolt mine down but as i understand it these units are not waterproof, so I am using velcro, and it doesnt last long, when out on the water in the hot sun the glue on the velcro, well it turns to an ooze. I fish alot and if it rains I have to put the stemwheel under my dash so it will not get wet. I was just curious how you and other do when your out and it rains
