hi youtubers  jeff cote here from pacific yacht  systems  we've got a question from richard  richard asks i'm rewiring my ranger 23  when i tried to replace an instrument i  found a tangle of wires behind the dash  not uncommon i've watched all of your  videos on marine wiring  and you always suggest crimping  connections  is there a reason you do not solder them  richer  well richard that's a really good  question and to be honest  in the marine world we're really worried  not only about a good connection but a  good connection  under all conditions which includes  vibration  and a soldered connection can get undone  when the conditions are just right and  you've got this perfect little vibration  at a single point on your boat and the  connection should could be broken  so yes you can solder your connection if  you need to  but to be honest all the high-end  builders ourselves  we don't actually solder any of our  connections we just do a really good  mechanical crimp  and we make sure that we use heat shrink  terminals and we've got a good  connection and we definitely do a pull  test  but there's really no reason or no  requirement  to do soldering in a marine environment  so it's certainly going to make your  life easier while you're fixing that  mess under your dash  if you've got further questions or you  want some clarification on a marine  electrical  send them our way thanks for watching
