Review on 🛥️ Seachoice 41801 Self-Parking Boat Windshield Wiper Kit: Easy-to-install 12-Volt Wiper with Adjustable Arm, Wide 110-Degree Sweep, and High-Performing 11-Inch Blade by Andrew Davenport

It took me a while to get started. That works fine. Suggestion: You must have some electrical know-how to install. When the old boat without self-parking detects this unit walk the way for self-parking. So if you remove power, you will need to rewire the system and add a second ground. The instructions could have been a bit better as the wiper blade was a puzzle piece that didn't click into place in my hand until I realized it had to be pulled out to lengthen it. Worth the price. Make sure you measure your shaft needs. This model is quite short and had to cut some of the rubber bushing to fit the jam nut on the shaft.
