Check the original dealer and/or his jobber. otherwise a call to staten island boat sales (sibs) should get you the answer. you should be able to trace the wires though, either from the thruster, the charger or the battery switch. that boat is often equipped with a stern thruster. so the battery may be in an aft location.. During the boating season, the batteries are able to supply both small constant loads as well as heavy but short loads for the use of a bow thruster. vetus offers 2 different types of marine battery series with its own characteristics.. My new (to me) boat has a max power ct 100 bow thruster. there are 2 batteries powering it, both agm type. presumably due to bad connections, the battery posts are damaged (melted) so going to replace them..
