Re: radio and amps
What year, make and model of engine are we talking about. They are not all the same you know. The alternator may be as low as 6 amp or as high as 16 amp depending on engine. A boat with a 50 HP engine would fall in the 16 - 17 foot range and hardly in need of an amp but to each his own. The alternator output has nothing to do with how big and amp you install. It has a bearing on how long it would take the alternator to charge the battery however. The larger the amp, the less time it will take to discharge the battery.
