works gret

makes flushing my twin Yamaha engines how much easier task easy to install easy to use

Eric Fajardo
Great product

Makes flushing a lot easier especially since I keep my boat in the water and kept losing O rings.

Mike T
Not complete for Twin Engines

The description sounded like this for complete for twin outboards but it is not. You have to buy 2 packages.

Hey Mike, that is correct. The product is packaged for 1 outboard. So you would buy 1 for each outboard.

Glenn Wilson
Fl Boat flush

Works as described but is pricey

Quick connect

Great product, works well. Pricey for a couple pieces of plastic though.
