StartGuard™
The abrupt DC system voltage drop that accompanies engine starting can cause microprocessor-driven communication and navigation electronics to “dump” programmed memory.

StartGuard solves this problem by providing supplemental voltage to sensitive electronics while the engine is cranked. It contains a sealed rechargeable battery which is switched on-line to electronics when the starter switch or solenoid is engaged. When the engine is running StartGuard automatically goes off-line and the internal battery is recharged by the alternator.



Specifications
Input Voltage: 13.8 - 14.8 VDC nominal, 15.5 VDC max.
Relay Activation Input Voltage: 7-15 VDC
Output: 20 amps max.
Battery:
12 VDC, sealed rechargeable,
5 - 7 year life (typical)
5 amp-hour capacity
Certified by DOT and IATA for shipment by air
Replacement battery P/N: 591-0412-0

a better move than using this thing is to have the electrical system set up properly."properly" being,the engine batteries are seperated from the "house",or "12v system" batteries...
if your electronics crash during start up,your boat isn't set up properly...
