hi Jeff Cote with Pacific yacht systems  what we're going to talk about next is  isolation transformers what is an  isolation transformer and why should you  care or have one on your boat  we you'll find a lot of boats actually  come with an isolation transformer and  it's really a really good way to protect  your underwater metals from Straker and  corrosion it's really there's really no  downside of one of these devices other  than three variables one is the price  the weight this unit weighs about 250  pounds and the volume in an ideal world  if we all have large boats with lots of  space and money wasn't an object every  boat would have an isolation transformer  right it's a way for you to guarantee  that you'll never gonna have reverse  polarity on your boat it's a way to make  sure that you're not gonna have straight  current corrosion on your boat from AC  shore power sources so really there's no  downsize and when you buy them you buy  them based on 30 amps 50 amps some come  with boosts there's all these different  models this is generally a long lead  time because they're actually made to  order but it's a great product and we  install them a lot on boats that are  probably in the 40 50 and I've even done  sailboats well I've done a few syllables  that are in the mid 35 range and the  owner was really concerned he was in a  bad marina lots of street current and he  wanted to make sure that his underwater  metals his prop at his shaft because it  was a folding prop we're gonna be  affected and so we ended up installing  an isolation transformer if you've got  more questions about our isolation  transformers reach out to us thanks for  watching
