Long story short, I was towed in due to a dead batery. After getting a brand new marine dual purpose battery I fired up the engine and put a meter on the batery. I was getting 11.9 volts. I tooke my rectifier out to look at it and realized it had lots of corrosion of its internal components, so I got a new one. Now with the new one installed at idle I'm getting 15.5 volts. My concern is that I will cook the batery. I assume that somewhere around 13.5-14.8 is normal range. Any insight on this would be great. The motor is A 1986 merc 75 HP 2 stroke, 4 cylinder. Thanks in advance.
