    Sucked a mermaid into my water intake

    Just kidding. But I have a problem that’s equally weird. Anybody have a standard accessory power wiring diagram for a Merc 5.0 Alpha 1 Gen 2? The boat is a ‘99 Sea Ray 210 Sundeck. The problem I’m having is that when I hit the trim toggle, it shuts off my stereo. Up or down, both do it...

    Would this work for saltwater flushout?

    I have an ‘01 Sea Ray, 5.0L Merc w/Alpha sterndrive that lives on a mooring buoy in saltwater. For various reasons it’s not practical to flush it with freshwater more than a couple times per season so I’ve been searching for another way to abate corrosion. Wish the Volvo Neutra system worked on...
