Review on Good Vibrations 140 Doctor Tune Up by Jeremy Black

I have three different outboard motors and I tune them myself. This tool was made especially for the master. It has everything you need to quickly change and clean spark plugs. If I could improve one thing it would be to redesign the storage system inside the product to accommodate additional power outlets. I put mine in my tool box but I'm afraid they might get lost over time. Otherwise a great product at a great price. must be for me
