I was on a trip and doing some ordering of parts for the electrical in the stern of the boat. I needed to estimate the distance from the battery to the engine for battery cable, and was trying to go by memory. I used the mercruiser battery cable length estimator chart and then went one size bigger, just in case. I went on line to order what I needed and couldn't find the size I wanted, but was able to find the next size higher on ebay for a good price. So I ordered it. I also ordered some tinned copper lugs and a hydraulic crimper. Let's just say my memory was a little exaggerated. When I got home and opened the box with the cable, I was a bit stunned to see the size of the cable... it was massive, and there was a lot of it. The good thing is, I won't have much voltage loss. :facepalm:
The lugs were pretty good except that they weren't completely sealed by the tinning and since air could get through, water could get in and cause corrosion. A little solder solved the problem. The crimper worked well and the cable ends turned out pretty good.
