Hello, I have a 18ft pontoon with 2004 25hp merc. Used mostly for
fishing. I would like to intall a second battery to help with my depth finder
and downriggers. I am concidering a Perko. The instruction say run a ground
wire to the engine block. Isn't the black starting cable grounded? Can I use...
Hello. I am putting a 2004 merc 25 4stroke on my 18 ft pontoon replacing a 1991 two stroke johnson
motor so all the cables are old. Is this a job for a do it yourself or should I
enlist professional help. I am located in the boonies so it is hard to get to
a dealer. Thanks for any help. vol
