[Music]  hi Jeff Cote with Pacific yacht systems  what we're gonna talk about Nexus  alternators and why that's interesting  as a boater is it's really a way for you  to recharge your batteries while  underway or if your engine is running at  idle which is not a good thing but  basically your engine has to be running  for an alternator work we end up  swapping alternators quite a lot or even  what we do is maybe not swap them but  actually modify them for external field  external regulators so we've done a  video on external regulators and you can  end up buying one of these alternators a  high output alternator like this ball  Mar here and actually work in  conjunction with an external regulator  what's really nice about basically a  specific marine alternator is that  they're gonna be wounded this is a way  to say that basically they're gonna give  you high output at low rpms car  alternators are really meant to work at  speed when your engines actually you're  running not at ten kilometres an hour or  fifteen kilometres an hour which is a  function of rpm but really running when  you know you're at high speeds 100  kilometres an hour or maybe 60 miles an  hour so what's really nice about a  specifically built marine alternator is  that you're gonna have high output at  low rpm and so that would be one of the  reasons why we end up changing those  will also end up choosing an alternator  in sizing an alternator for the battery  bank that you have installed on your  boat and a lot of times that's going to  be your house battery bank and as many  boaters don't have a generator how do  you go about recharging your house bank  that now is probably quite large or you  want to have quite large and you want to  do it quickly efficiently so sail  boaters for example on my boat I've got  a hundred and twenty amp alternator and  I'm gonna have a single V belt and I've  D rated the alternator and I bring it  down so that it's outputting about 90  amps but we've done alternators up to  220 amps even I've done on a big engine  a 300 F alternator you can have them 12  volts 24 volts and there's all this  choice out there and ultimately the goal  for you as an owner as  boater with your alternators how do I  get all the energy I can one my engine  and I'm underway so that my batteries  get charged as much as possible so when  you get to your destination you can use  your batteries for another day  two days and then start the process all  over again if you've got questions on  battery alternators engine alternatives  feel free to reach us at pacific gas  systems thanks for watching
