Thought I would post this on here also--- motor is a 2013 300XS 1E051919
Bought this unit 6 months ago to replace an aging jump box that I successfully used to start my 3.2 ltr Mercury on a couple of occasions.
Was convinced after posting questions and reading reports that it would have enough juice to start this big outboard in an emergency.. (WRONG)
Fished a tournament this weekend that started out in sub freezing temperature.. motor would turn over but not start. Grabbed my new NOCO with confidence and proceeded to get disappointed... Had to pull the boat out and put a quick charge on it to get it started.
This is the 1st Mercury I have owned that I could not jump from a hot trolling motor battery if needed.
After that 1st failure I purchased the largest output old style jump box I could buy and carried that heavy booger for about 4 years and did successfully use it once.
A few months ago after reading up on these new wonder starters I bought into it..
