Repeated use of the OEM relays with low battery voltages will eventually degrade them, to the point the engines will not even start, possibly leaving you stranded, or dead in the water. These relays have a much wider range voltage spec, so work at lower voltages, and seem to last much longer in these boats as a result. (OEM relays are rated down to 10v minimum, these Song Chuan relays are rated to operate down to 6v!) I highly recommend all Rotax boat and Sea-Doo PWC owners keep a few of these on hand as spares, they are cheap insurance! You need two per engine in the Rotax-powered boats, most Sea-Doo PWC use one. As the founder of the global Chaparral Vortex jet-boat owner's group, I've recommended these many times to our group members, with good results, highly recommended.
