I installed a Marinco 33505 Windshield Washer kit with the AFI Deluxe Wiper arms and it came out great! I had a spare switch not being used at the helm that I use to energize the motor.
Only issue I had originally was the bracket that the tank hangs on cuts into the container over time and it will leak. They replaced it for me and it seems it would do it again, so I installed it this time on the floor behind the berth panel that I installed hinges on last year to access my mid section batteries and switches.
The first time I installed it, I mounted it to the side door in the berth that opens up to the head valve and wiring chases.
Overall, I really love it as it helps clear the windshield after the salt streaking. The best fluid I found that does not stain everything is the yellow prestone de-icer.
The AFI deluxe wiper arms solved a lot of issues as well since they can now hinge out away from the windshield making it much easier to clean up and replace the wiper blades.
