Switch Hitter: More than one windshield wiper often leads to more than one switch. Which one do you hit when you're getting attacked by spray? Replace those switches with Imtra's IMW electronic wiper control. The panel operates up to four wiper motors. With its compact 3"-by-3" design, the panel can be retrofitted or newly installed and operates small-boat wipers from Roca, AFI, Speich, AM Equipment, Vetus, and more. The unit also features a wash function that sends a spray of cleaning fluid to the windshield, then times the wipers to swab away grime. Price: $325.
