Re: Fletcher Arrow
+1 what Fisherball stated...
Also, I would recommend that you have a second battery...preferably a deep cycle battery that you would use to run all of the accessories while you are just floating...like the radio, any lights you might need on, etc...this is called a house battery...the reason for the deep cycle type, is that you could use it to the point of almost running it "dry" and it will be just fine after a good charge when you get home...this also prevents you from draining your Engine Start battery when you are out there...if the deep cycle battery is not dead, it could also be used to start your engine in the event that the primary start battery is weak...and, with a proper battery switch, they can also be joined together to crank the engine...similar to one of these...
It is a rather large expense at the outset, but if you take good care of them, they will last you a long time and add a margin of safety to your boating pleasure...make sure you get an appropriate charger for them...that will contribute to their longevity...
Happy Boating!
