Some of the mobile video sites for car audio have weather proof monitors...Ive used them before doing installs for truck beds when I was in competition..You cant "splash or wash them down" but if installed right say behind a windscreen and are removable you should be fine...They draw minimal power, all of my electronics and livewell pump run off a dedicated battery, i have an 898c and 1198c and have been on the water for 11 hours running all and have had no problems.
