The factory generator kit included a new solenoid box cover that was deeper and included a 10 amp 12 volt regulater. We who installed these kits found the left over solenoid covers to be very handy to store the nuts bolts and screws of the motors we serviced. Since the outboard has an excellent magneto, the battery is only used for starting. A properly tuned motor will (should) start in three or four revolutions. Prolonged cranking indicates something is wrong and should be corrected. (Prolonged cranking WILL overheat the starter motor and can melt the solder that holds the armature together.) The heavy duty marine battery recommended by the factory will last over a month with normal use. (I used two heavy duty six volt batteries in series.) They went all summer with nary a whimper. A trickle charger may be used at a permanent mooring site, but the motor must be clear of the water to avoid electrolyses problems.
